Trying To Fix A TOSHIBA TV With NO POWER

This Toshiba 42YL863 LCD TV has no power. The internal fuse has blown and been replaced, but it still won't turn on. Will I be able to fix it?
Hope you enjoy!

Steve, the coil is open circuit. Those coils pass the 240vac on both sides. One side is open. On resistance, you should see roughly a short through each side. The thermistors are probably ok. The coils provide some filtering of noise from or to the mains supply. Also, have you ever heard of a dim bulb tester? It's a device that allows you to let a controlled amount of current into a device. It would let you connect up the TV or other equipment without blowing the fuse. Basically, it puts a bulb in series with the AC supply rail, and in doing so limiting the current / wattage allowed into the device to the wattage of a bulb. If the bulb shines bright, you are drawing the full wattage of the bulb, if it's dim you are only drawing a small current or wattage through the bulb. Its a way of protecting the device by limiting current flow into a piece of equipment. If you switch out the dim bulb, it allows the full current to flow unrestricted, and a fuse will blow if the equipment has a short on the supply rail. Another device you should be using is an isolation transformer to give you some level of protection from electrocution. Good luck.

[@germancarfan]

I have repaired a few tv's normally I just opt to replace the complete board if I can't see the fault quickly. Hats off to you for trying. I just see you have another video on this will watch that now

[@Madmanguruman]

My far-too-late commentary. (I have more than 20 years experience with switching power supplies.) The coil is most certainly a common-mode choke for EMI suppression. There must be DC continuity through each coil for the mains to reach the bridge. The small components shunting the coils are likely transient suppressors (varistors). At 240V they will be open-circuit. They are meant to suppress high voltages that can be induced by input surges (lightning strikes on the mains,.etc) as the CM chokes can 'ring' and boost sudden input voltages to insane levels. (Normally there is a single large thermistor in series with the input for inrush suppression.)

[@JVerschueren]

To add to the far-too-late commentary: true, but, the coil being open circuit is just stopping the fuse from blowing again(*). If he fixes it, the fault is still going to be there. Anyway, let's watch the follow up. (*): which is odd as it shouldn't have gone open circuit along with the fuse. I would have expected to see *WAY* more carnage in the rest of the circuit if the faults were related.

[@KorAllRBare]

Plenty Of Comments already about a possible short which stressed "Burnt Out or open Circuited" that Choke, if there are no shorts across the voltage rails "Voltage Test Points to Ground" The choke can be rewound and soldered to it's original points, make sure the windings are returned to the correct turns if there are 12 turns then make sure you end up with 12 turns.. Check every other board and their Voltage Test points to ground as well before connecting them to the power Board, As the Power board will fail as soon as you connect any board with a short in it's supply rails. The Thermistors on the Power Board I believe should have a specific resistance to them when at room temperature BTW, So I'm guessing they too were stressed out to end up open circuited like they are, They need to be replaced with the correct values before testing or applying power to the Board as they are there for the protection of sensitive components on the Board and all those other Boards

You can desolder the coil from the board and test it scrape some of the insulation off the coil and/or unwind the coil and see if there’s a break in the coil since you can’t get another part...

[@StezStixFix]

Thanks Darren! I'll definitely do that! 👍

[@mojoblues66]

the coil is just a symptom, it makes no sense to replace it without knowing the cause of the blown fuse.

[@toolsarecool]

Those axial components you desoldered are indeed very likely NTCs, probably used for inrush current limiting. I agree with those who recommended hunting for the root cause of that common mode choke/coil to fail open, vs. having it's lacquer melt and short windings. That must have been quite a bit of instantaneous current flowing through that thing. The bridge rectifier is a prime suspect, assuming you can't find any shorts on the DC side once you took it out. Fun stuff!! :-)

As Fuzzy electronics says the coil has gone open circuit. But to have gone open circuit a lot of power must have gone through it. That would suggest something major has gone short. If you do get another coil check for shorts before putting any power into the board. It is possible that the short has gone open. But this would produce a lot of heat. My suggestion is take the heat sinks of the components as you may find that there is a crack in the faulty one or it may just crumble away.

[@StezStixFix]

Thanks PDS! Yes, excellent suggestion. I'll get all the heatsinks off and check all the components under them! Much appreciated! 👍

[@teropirttimaki]

Like stated, the first winding is the issue, of course i cannot really shove my face to the board to confirm is it. If the fuse blew up with in 10 minutes, then there has been short near the ac. I think you did check the caps so then next in line to check Degauss Posistor - very likely. Horizontal output transistor. Power supply regulator if there is one. Power supply chopper (switchmode) transistor if there is one. Diode(s) in main bridge Main filter capacitor(s).

[@ESS1024]

These small 2-pin devices are spark gap protectors and they serve to suppress voltage spikes across the coils of the common mode choke. Spark gaps are OK, the common mode choke is not. Likely the coil is damaged somewhere near the points where the enameled wire is soldered to the pins, and often this can be fixed quite easily and you don't need to replace this component. But I doubt that's the only problem.

[@mojoblues66]

For testing he could have just bridged the spark gap.

[@fuzzybobbles]

The coil is there as a choke filter on the mains input side. Looks like one side of it is open circuit. Probably burnt the coil when something shorted and also blew the fuse. I think something else has shorted further down. Probably a diode has failed short circuit. I'd be removing the bridge rectifier and testing that as a starting point. It's always best to test them out of circuit.

[@StezStixFix]

Thanks Fuzzy! I'll definitely do that, really appreciate the info! 👍

[@jimmyramkisoen191278]

Yes i put my money on this reaction :)

[@lnFernemLand]

I was gonna comment something similar to this. That coil might be burnt, thus causing the short. If something so dramatic happened that even physically blew the fuse up then I'd suggest checking all the caps off circuit as well. They might be damaged because of the over-current that flowed through the circuit.

[@StezStixFix]

@@lnFernemLand Appreciate that, yeah, I'll check them over too!

[@markbriscoe8526]

Did you check the 5 V rail? Standby the TV uses 5 V standby you need to check where the standby voltage comes in. If it’s below 5 V then you know you’ve got a problem with the TV and the power supply.

[@skypirate4806]

Hi, those Coils, is one side Positive and the other Negative?, seems like the 3v AC may be where the other side isn’t passing through the first Coil, may be the Negative side, so you could be right, the first coil has a break in the Negative side. Just a thought.

[@leewright6101]

replace thermistors , u can use the black disc ones same thing, from any tv, but thats gone more than likely a mosfet under one of heatsinks has gone short, common is that a vestel psu..

[@ralphj4012]

Whilst you could remove and ‘bypass’ the choke for test purposes the fault that caused that choke to fail and then blow the fuse ‘when the TV was on for a while’ needs investigating first, otherwise if the fault is still there then any replacement choke will also fail. Ideally remove the bridge and then check it out of circuit followed by high DC voltage, current- protected injection into the bridge output. High voltage power supplies are not in everyone’s toolkit however. If you have a variac with a light-bulb limiter than that could be connected to the input of the bridge (first remove the coil nearest the bridge). A failure after a time period may show itself by the lamp becoming bright. Circuits that fail after a time period are always the most difficult. A circuit diagram would help (the second ‘non blown’ fuse may be in the low voltage side perhaps pointing to an issue in the high side, one or more FETs or something has failed in the switching circuit).

[@StezStixFix]

Thanks Ralph, really appreciate the info. I'll definitely be having another look at this, as I want to see what's going on under those heatsinks. I should really have removed them first time around, as you're dead right, that choke didn't fail by itself! Thanks again for the info 👍

[@ralphj4012]

You are welcome I did forget to mention also having another look at those varistors which are usually there to reduce inrush current, though being connected across the coils is a little odd. Good luck with the repair.

When my friend gave me a TV last weekend saying if I can fix it, it's mine to keep, I admit to thinking "I hope it's something simple, 'cos I'm going to be in over my head. 😬". I can confirm however: T# fuses are time delay, so they resist for a while before blowing (as opposed to F#, which are the more common fast blow). ✔️ Thermistors are thermal affected resistors. ✔️ No idea how to test them, like you say, because they change with relative heat. I agree that Flib and Fuzzy are plausible with the coils. Not knowing much about the internals of a TV, I wonder if there are two near identical circuits to run alternate TV lines in the screen for each refresh (if this theory isn't clear, check out episode 3 of my "Electronics For The Lesser Knowledgeable" series which covers TV and region compatibility). Just a theory. Worst case scenario, you could claim to be a rockstar and launch the telly out of the window. 🤘😂 (Don't do this, kids - it's dangerous and irresponsible. Plus it doesn't spectacularly smash like the old glass fronted CRTs, like the Who would've had... I mean, don't do that either.

[@anjumimran7042]

5 voltage standby you check

[@ianhaylock7409]

there's no 5v because the choke is open circuit.

[@jonskitch8082]

Use dim bulb tester, this will protect the circuit and fuse! The bulb will light up when there is a short!

12:17 Why don't we go get a schematic then? Unless Toshiba are one of these companies who copyright all their manuals and won't let anyone see them...APPLE !

[@murraymadness4674]

I'm trying to fix a 42HL96 and was shocked, totally shocked, that I found a service manual online that shows the circuits. Mine is stuck with 3 flashing yellow, indicating power fail...or it needs a remote, can't be sure which. I plan to make it run on 12v dc, so will probably just scrap the ac power board and replacing the high voltage backlight with high power leds..if I can get it to work.

[@Wasper216]

Afraid of 240V but keeps fiddling around with his hands close to the board while talking 😂

[@OOOHBILLY]

FAILURE!!!!! Lolol jk. At least you’re trying it.

Haha, thanks Wolli! It's on my "to do" list! 😁

@@StezStixFix my mate vince has some good tips but only for rollers.

[@TheTenchiOni]

There are capacitors with their internals melted out of them. The power supply is done. Period.

Anyone who works on a TV without an “Isolation transformer” is a bit silly.

[@b2d327]

Your friend shouldn't be embarrassed for his soldering skills, he should be embarrassed that he bought a POS from toshiba

[@deanavitch]

Just bypass it!!

[@deanavitch]

Make sure you remove the coil tho when bypassing it

[@StezStixFix]

@@deanavitch I was tempted to do that, but wasn't sure how safe that would be? 🤔

[@deanavitch]

It looks as though a balanced coil setup so cancels out any noise on the mains supply that is all

[@StezStixFix]

thanks deanavitch! I did think it may be some kind of filter. Appreciate the heads up! 👍

[@housinit]

Is it just me, or am I seeing a whole bunch of water damage on that board?

[@michalbalicki7267]

Don't buy Toshiba they break down & Toshiba don't want to know after the year is up & you have a fight with the retailer to get a repair

[@gaazag6643]

what a waste of time
