#imbrysokad hello sir I'm from Pakistan i m regoler watching your channel of all videos you master of all LEDs and electronics equipment I like you your great sir 👍🎉🎉
Hi tevz from Sydney Australia. Thank you for your time and teaching. * After continuity of fuse looking for the cause. * I'm thinking instead of attaching a resistor use a Variac 60-120V if the fuse doesn't blow increase to 220V 🌏💫
HI MR TEVZ how are you and the family doing hope everything is ok after the flat.you have miss on this channel by everyone and me ,,,,sins we all learn so much from you including me thank you god bless
thanks tevz it is informative. We naturally changed the fuse that is OK and also if we would have used a proper varistor (for instant 400V) is that possible and better?
Sir you are great 👍 I have a question 1)Is there any disadvantage of operating without the mosfet. 2)Can all power supply circuits work without the pfc or there are specific ones
I join my colleagues to welcome you back on stage. Hope your family is fine ? So so sorry for the ugly incident Master. Pls, accept my pity & it wouldn't happen again 🙏🙏
Sir until now i cant find what parts in this unit was giving the trouble pls help.hisence 58A7100F..........May i ask what is this cm121k.1n ic.. is this a protection ckt in the backlight drver.what. pin in this IC was the protect ..thank you.
Where is your location sir ...if you dont mind Sir if you have messeger iwill send you the picture of this board..to indicate the voltage and testpont .to made trouble shooting easy to me.
Hello . My name is Robert. And I have a problem with a pfc tcl led tv power supply . Board # 40-E04022-PWF1XG . On the output pin this is no power on BL_ON , P_DIM ,P_ON . No 5v power output . 12volts out is 11.5 volts to power the motherboard . How can I fix this problem ?
Well, obviously removing the PFC works ... but why not just replacing the MOSFET? I mean ... if customer pays for it of course, missing PFC is on his electricity bill 😄
Most replacing the mospet is not guaranteed to work; if the mosfet gets short, the driver also gets damaged. The PFC only gives about 5 % less of the electricity bill.

I wish I had a quarter of your knowledge - you are the greatest!
Happy to see you back in business after the flood...
From iraq I sent ❤ and respect for you sir.

Glad to see you again ! Thanks ! 😍
Saudações aqui do Brasil, que bom que o senhor retornou , um forte abraço
MAESTRO thank you very much for the video👍👍👍
Glad your back repairing stuff again. ❤ fron the uk
Thanks 👍
sorry for those who lost there lives in the flood in your country may there souls rest in peace ✌ happy to see you back
Im happy you are back
Well done sir. Sorry for the damages due to the flood. ❤❤
Thank you, I appreciate your concern.

hello sir I'm from Pakistan i m regoler watching your channel of all videos you master of all LEDs and electronics equipment I like you your great sir 👍🎉🎉
thanks a lot clear so far
Watching from India.Thanks a lot to you sir...
Witching from Kenya big up bro
Thank you sir
galing master...god bless.
So beautiful sir I am watching from Pakistan ❤❤
Thanks for the info
Another great lesson - thank you!!👍
I believe you are a great fan of Mr Sorin the owner of " Electronic repair school" RUclips channel ❤❤
@@ONAHANDSON YES, I am, although I don't get many laptops. He is the reason why I started a repair business 4 years ago.
Nice master galing mo tlga
Exellent .....
Ab BRILLIANT BRAIN YOUR SKILL THANKS👍😁

Would a dimmer work? Of course, as long as it respects the power it offers.
Watching po
Well. Boss
good
👍👍👍👍👍
Good job sir
Watching fr Pampanga
HI MR TEVZ how are you and the family doing hope everything is ok after the flat.you have miss on this channel by everyone and me ,,,,sins we all learn so much from you including me thank you god bless
All good
Good sir❤
good 👍👍👍 yes❤️
Thanks sir
You're welcome 👍
❤❤❤👍
thanks tevz it is informative. We naturally changed the fuse that is OK and also if we would have used a proper varistor (for instant 400V) is that possible and better?
👌👌👍👍
I guess I'm a visual person. I prefer an incandescent lamp to a resistor. You can quickly tell by the glow of the filament or its pulsation.
Sir you are great 👍 I have a question
1)Is there any disadvantage of operating without the mosfet.
2)Can all power supply circuits work without the pfc or there are specific ones
It depends on the power supply circuit.
please tell more about removing mosfet . why????
Sttange method how to use solder vaccum pump..

i have a samsung ua55eh6000m tv with ghosting image verticle on far right side, please herlp me understand problem,,, t con board or??
Sir until now i cant find what parts in this unit was giving the trouble pls help.hisence 58A7100F..........May i ask what is this cm121k.1n ic.. is this a protection ckt in the backlight drver.what. pin in this IC was the protect ..thank you.
no data sheet. no idea
Thank you sir .i hope you will help me later on
The issue of the unit is no red indicator light but there is 3.3v stby .we have also 12v .5v and 1.8 v when power is on
check other voltage
@@tevzTVTevatronicswe also measure 1.2v....in the main board....also i measured vgh 28v and -8vgl etc......in tcon board
Where is your location sir
...if you dont mind Sir if you have messeger iwill send you the picture of this board..to indicate the voltage and testpont .to made trouble shooting easy to me.
What about the PFC diode, you must short it...
No need
@tevzTVTevatronics but in other video you shorted it
What is this resistor for testing? 😊👍👍
Der Widerstand den er hier benutzt beträgt 220 Ohm 20 Watt! Man kann aber auch eine Glühlampe mit 230V/ 25 - 100 Watt in Reihe schalten.
@@HeidiHoh thank you very much and best regards

with large size screen what wil be the results. why you did not ues power module if the component not available at your region
pfc
Why not swap the mosfet than disabling the entire circuit
Replacing the mosfet is not guaranteed to work. Mostly when the power mosfet is damaged the PWM driver is also damaged.
Well, obviously removing the PFC works ... but why not just replacing the MOSFET? I mean ... if customer pays for it of course, missing PFC is on his electricity bill 😄
Most replacing the mospet is not guaranteed to work; if the mosfet gets short, the driver also gets damaged. The PFC only gives about 5 % less of the electricity bill.
Now, I think you can repair all TV
So it works without varistore and without pfc mosfet?
