Bypassing the PFC circuit.

[@samuelmatos9124]

Tevz, you are very practical and an excellent technician. Please keep teaching us how to fix components like a professional !! Best.

[@CircuitGroupInternational]

Nice job disabling the APFC circuit, in some smps the protection circuit has to be disabled also. Great 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

[@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

[@ONAHANDSON]

Good work❤

[@pedrojuarez2688]

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

[@tevzTVTevatronics]

220 ohms

[@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.

[@BenjaminLolik-ft1bd]

Thanks you it is very interested sir.

[@bobanmanic1235]

Thanks a lot for the video.👍

[@DomingoBautista-i9d]

Thank you sir

[@suatbulat9599]

👏👏

[@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

[@HabipAydinbeyli-ts2ei]

Thank you

[@hasantamer9199]

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

[@nankinanko5790]

If properly removed, it'll work, unless other components are faulty. The main disadvantage of removing the PFC circuit is the poor power management caused by the inconsistent current drawn.

[@bineshchauhan8713]

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

[@Electricworld-1]

Hello, Tevz. I hope you're well 🎉

[@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

[@ZafarIqbal-qy9qe]

❤❤❤❤❤❤❤

[@AssaneTraoré-v7u]

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

[@mujjuk1157]

Hi sir iam in tamilnadu

[@shenbagasankar5479]

Did you repair that tv?

[@protection4541]

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

[@tevzTVTevatronics]

if necesary

[@johntripod8583]

How much did it cost the client...

[@jeanfrancoislee7350]

Hi tevz ,i have a saba led tv ,always in standby don't switch on .all diodes in secondary are ok .can you help thanks

[@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

[@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.

[@محمدلافيللالكترونيات]

أنا فني الكترونيات من مصر ممكن نتواصل معك

[@rduwe9466]

i have a question i have a sharp tv that makes a hard pop when turned off , could it be a capacitor in the audio circuit?

[@orange11squares]

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

[@Ravi......]

Thank you sir ji🙏🏻

[@tevzTVTevatronics]

Most welcome

[@thunderbolt4002]

Resistance value type please sir

[@tevzTVTevatronics]

220 ohms

[@thunderbolt4002]

Thanks sir

لقد اوقفت عمل pfc

[@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

[@potassium69]

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

[@Невидимка-ц4щ]

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.

[@arkanghelkerubin1980]

Why don't you remove rhe varistors sir

[@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..

[@xrahmane]

The process will not always work🙂

[@praveeenkumar2692]

What is a PFC circute??

[@Невидимка-ц4щ]

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.

[@mahmoudnaser453]

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

[@thirunahariprabhakar6560]

😂

[@DrHarryT]

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

[@pDmytro]

На люмінесцентних лампах не запрацює

[@mahmoudnaser453]

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

[@tevzTVTevatronics]

power factor correction

[@upsolm]

[@mahmoudnaser453]

ther,s adestortion near you

[@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!
