Re: Kd-55x80j
Were you able to remove the cover?
I tried to follow the manual but still can not remove the back cover.
Another question. If the TV shows 6 red blinks, does this mean it's bad LEDs and they need replacement?

Re: Philips 47PFL7403D/10
Yes, just read above.
Make sure you get FSQ510 from a reputable seller like digikey or mouser
Someone who worked on the board before me replaced it with a fake chip, and I purchased fakes from ebay too.Last edited by zape; 12-16-2020, 12:07 AM.

Re: VIZIO M50-C1, powers on, no backlight, no picture
I used a heat gun and a thermal sensor placed close to the heating area with some thermal paste
Heated it up to 240C, kept it at that temperature for 10 seconds and it fixed the TV
Here is the heating area...Last edited by zape; 12-05-2020, 01:00 AM.

Re: LG 50PJ350 plasma blowing Y-Sustain board
Tried to fix my TV today again.
Replaced fets, turning on, a few seconds, magic smoke, and all 6 fets on y-sus are blown again, along with R503
Sadly, but this is my first TV (out of ~20) which I could not fix.

Re: Samsung UN60J620 Backlight or PS?
in my case it was both the D9001 diod and the LEDs, almost half of the leds were dead

Re: Samsung UN60J620 Backlight or PS?
Just checking it to say thanks to budm
D9001C was faulty in my case too.
replaced it with some random high voltage diode and the TV is workin!...

Re: Insignia 24” ns-24e340a13 LED HDTV
I guess you take it out of another ns-24e340a13.
This TV is BER. It's easier to buy another used 24-32" TV for $20-50
I even see sometimes they give these away.

Yeah I wish @tom66 was more active these days I saw his old posts around plasmas were very helpful.

Re: LG 50PJ350 plasma blowing Y-Sustain board
Yes I bought it from eBay as "not tested" but it does not matter now as it's blown now.
I did check the buffer boards for continuity and it tested good, but as you can see the image on my tv is in the very bottom that makes me think it could be still something wrong with the lower buffer board. I had similar symptoms with another TV what had bad buffer IC.
Is there a way to check if the panel is bad?Last edited by zape; 09-09-2020, 01:24 PM.

Re: LG 50PJ350 plasma blowing Y-Sustain board
Did you fix both of your boards? Tested? so I assume asymmetric reading on R437 is expected and something is wrong on my other board where it reads 150k both ways

Re: LG 50PJ350 plasma blowing Y-Sustain board
Yes I did check the IC 704 when you mentioned you replaced yours and mine reads good on both boards.
The original board had shorted Q22, Q24, Q03, I bought the replacement board and it died in a few seconds after I turned the TV on. I'm not sure if the replacement board was good though. But the Q22, Q24, Q02, Q03 fets were good, these were the only fets I checked on the replacement board before I plugged it in.
I also decided to use 30F125 instead of 30F124 on the original board just because I thought it's a better FETLast edited by zape; 09-09-2020, 12:44 PM.

Re: LG 50PJ350 plasma blowing Y-Sustain board
Yes I will try to check all FETs and resistors
What resistance do you measure across big R437?
on one of my boards it's 150k both ways, and another board shows 150k one way and 200k if I swap the polarity...Last edited by zape; 09-09-2020, 12:17 PM.

Re: LG 50PJ350 plasma blowing Y-Sustain board
I'm also working on the same TV. Here are the symptoms [url]https://photos.app.goo.gl/cgFEzQ5YE5vqzmdv9[/url]
I also happen to have two Y-SUS boards which I'm trying to repair
Both boards had Q22, Q24 and Q03 shorted. I now read through this thread and also discovered an open R503 on one of the boards.
Also, if I keep the TV on for more than a few seconds, it blows the FETs again.
Don't give up, I hope we can somehow work together through this and fix this plasma TV!
P.S. Here...

Re: Samsung Plasma PN51F5300 not turning on
Probably Y-sustain board / buffer board is dead
Inspect Y-buffer board ICs for signs of burn
check Y-Sustain board for shorted IGBTs

Re: LG 50PJ350 dead, relay clicking
Yes that's exactly what I experienced with the replacement board,
The same FETs are blown. The buffer board is not shorted, so I'm a bit confused. Could this be something else, like panel?
I did find a schematic of a similar Y-SUS board if that helps
see attached...Last edited by zape; 08-21-2020, 05:04 PM.

MAGNAVOX 32MF301B/F7 versions interchangeable?
I see that there are 4 different versions of these, each has its own SN prefix (DS1, DS6, DS7 and ME3)
What's the difrerence?
Are the boards interchangeable between these versions?
