nice job master as always

[@BichiTech]

Hello sir fewest day a go I do not seen your post I hope there is no problem thank for your good job

[@tevzTVTevatronics]

All good

[@rajeshjadav1240]

Thanks. Good. Information 💯

This is phenomena 😮

[@jennysheart4546]

Thank you for sharing host

[@tevzTVTevatronics]

It's my pleasure

I've known the pfc to fail on atx psus. Good video and always appreciated your work x

[@tevzTVTevatronics]

Thanks 👍

Helo I am fan of tevz your channel always watching

[@AshokKumar-vh1pw]

Good job 👍

[@franciscofurlan4001]

One time I'll try do that , the tv work fine, but after short time can back, may be the power MOSFET of forward work so hard with 300 volts. Hope you are lukie this time. Excusme my bad English, Im Spanish from Argentina.

[@ONAHANDSON]

Good work❤

[@badonrani4059]

Sir can you make 1 videos explaining the schematic diagram of TV power supply with pfc section that will be helpful for us

[@olusegunlateef7571]

thanks for helping us cos we are learning from each of ur videos

[@noureddinecherradi5037]

Thanks, sir, for sharing this video

Hi sir iam in tamilnadu

[@shenbagasankar5479]

Did you repair that tv?

[@gerardoacosta5396]

any body can givme a hint by the way goood work sr yor videos are very good

[@GoogleEarthfact.]

Good job sir ❤

[@suatbulat9599]

👏👏

[@danielpeter6407]

Hello Tevz I have been very trill with your levelled deep and vast knowledge in electronics I really appreciate your relentless instructive posts of which am one of most benefited .may GOD reward you, I had a pfc issue with 26 inch Samsung lcd when I did the bypass it couldn't work .Please help how do I boost 300vdc to 390vdc to make it work thnx a lot

[@tevzTVTevatronics]

The only way to boost it to 390 volts is to repair the PFC. There are resistors connected to the main capacitor that you can modify to somehow start the main power supply. Example a resistor connected to b+ of the main capacitor value of 3.3 mega ohms. try to parallel a 2 mega ohm of that resistor which is connected to the B+ main capacitor.

[@franciscofurlan4001]

Pienso que para aumentar la tensión de 300 voltios se podría intentar hacer un doblador de tensión como traían los viejos tv de TRC que servía para trabajar con 110 y 220v.

[@Junior-ff7ee]

Great work as always thank you.may you consider show how to modifiy dual mosfet power supply like what you do with str w6053 .thank you

[@BenjaminLolik-ft1bd]

Thanks you it is very interested sir.

How much did it cost the client...

[@user-hn6rf6qt2g]

Thank you sir

[@bobanmanic1235]

Thanks a lot for the video.👍

[@msnerizaful]

You just short the connection of the diode which is directly goes to the output and cut the mosfet connection, is that it?

[@tevzTVTevatronics]

yes

[@chinnarao326]

Resp Sir! Very Nice Sir. Sir My HP Monitor Balack Sreen CPU Connected after Vertical Lines Sir Where the Problem Sir Please Advise Sir. -- ChinnaRao Paderu Andhrapradesh

[@tevzTVTevatronics]

[@Ravi......]

Thank you sir ji🙏🏻

[@tevzTVTevatronics]

Most welcome

[@protection4541]

Hello. If there is a short circuit in the circuit again after the repair, how will you notice the short circuit despite putting resistance in the circuit input

[@hasantamer9199]

good Hello, I am confused. Will it work or not when PFC is removed in all TVs?

[@pedrojuarez2688]

Greetings from Venezuela, excellent video, one question: what resistance did you place for protection?

[@tevzTVTevatronics]

220 ohms

[@bineshchauhan8713]

Thanks sir Where can I find a video describing such a pcb with its diagram please

[@amankumarmuraini369]

Thanks

[@estebansuarez2957]

Hola tevz y como hace la fuente el suicheo quede perdido si quito el mosfet y el pfc quede gringo como decimos en nuestro pais🤔

[@tevzTVTevatronics]

I just removed the PFC become like a normal power supply circuit.

[@thunderbolt4002]

Resistance value type please sir

[@tevzTVTevatronics]

220 ohms

[@thunderbolt4002]

Thanks sir

[@jennysheart4546]

Harang

[@gerardoacosta5396]

hellow you took two pices of the board it realy don need them for the right wayb t work of the tv , I don understend how it work whitout the mosfet

[@user-mu2fh8bx6l]

hello your video concerning food interests me. I have to admit that I didn't understand anything. can we remove the mosfet and cut a line and it works? help me I don't understand. I want to understand .

[@tevzTVTevatronics]

keep watching

[@mahmoudnaser453]

MOSFET& rectifier also shorted?????? what's going on?& mian capacitor?????

[@orange11squares]

why did you cut the trace that power the PFC circuit IC? removing the PFC transistor and diode was not enough?

[@techniqueskhalid9873]

sir i have a question about mosfet removing and replace to wire from schematic if you 300v and gnd are connected i think a short have can you explain pleaase and big thank

[@tevzTVTevatronics]

No short, look at the diagram.

[@techniqueskhalid9873]

But you have replace thé MOSFET of wire in vidéo Big thanks❤​@@tevzTVTevatronics

[@tevzTVTevatronics]

@@techniqueskhalid9873 that was a diode, not the mosfet.

[@techniqueskhalid9873]

❤❤❤ thank you Sir​@@tevzTVTevatronics

[@user-vv4tv5ln6l]

when turned on, there is no image, the indicator is still on, the screen lights up, there are black stripes on the candinsator for the backlight, 40 volts.

[@protection4541]

Hello, do you always bypass PFC if it is defective?

[@tevzTVTevatronics]

if necesary

[@pDmytro]

На люмінесцентних лампах не запрацює

[@user-vv4tv5ln6l]

where can you download the circuit diagram for the Skyworth TV Model No.: 32E3000 board number TP.V53WT.PB733 32STD2000

[@tevzTVTevatronics]

I have no idea.

[@xrahmane]

The process will not always work🙂

[@potassium69]

hello po san po location nyo and san po kayo ma cocontact?

[@richeobrador1976]

Sir idol dina po ba aalisin ang WD40 sa board, ang ibig kopo sabihin dina po ba lilinisin like thinner po?

[@tevzTVTevatronics]

hindi na

[@manuelvillanueva3753]

WD40 is non conductive, its safe to use on circuit boards..

[@AboElmoaty_Electronic]

لقد اوقفت عمل pfc

[@DrHarryT]

I don't know??? I would think that you wouldn't have to remove components and just jumper wire to bypass the PFC.

[@upsolm]

21:42. ?! Video editing

[@mahmoudnaser453]

ther,s adestortion near you

[@thirunahariprabhakar6560]

😂

[@mahmoudnaser453]

what's the meaning of the pfc?????

[@tevzTVTevatronics]

power factor correction

[@robinsutcliffe-video_art]

If I was the customer and saw how you undertake this repair (if indeed you are actually repairing it) I would ask for a refund and take the TV elsewhere. Absolutely brutal removal of components with the least possible amount of tools - try solder wick

[@Dark_Knight_USA]

Greetings: WD40 Mixed With Electronics? Hmmmm. O goody. U DIY / Ujunk idiots do that ...but Not in my shop!
