Re: Sanyo Plasma Display Problem Dp50747
tw2005, The cap showed no signs of being bad, no leaks or bulging. Will recap the low voltage ones on Y main also, doing the PSU right now, (hope I have all the right ones).
Tom I reseated all the LVDS and power cables to get the curtain of black when I first started, although I may not have reseated it properly the first time.
I will say after taking out the PSU someone had changed 6 2200uf 16v caps on the cold side already, even used Sanyo caps. So I guess the "Tech" did try something.
Thanks again for the help will post an after pic when done recapping everything.Last edited by MagicSmoke; 12-06-2014, 05:17 PM.Comment

Re: Sanyo Plasma Display Problem Dp50747*** UPDATE***
Finished PSU recap. Will do Y main tomorrow. But as promised....Before https://www.youtube.com/watch?v=xSewl8OINrA

tw2005 I don't have an ESR meter to properly check the 680 cap. I did put my meter set on 2k across the leads once removed and got no reading. Tried all settings and still got no reading. I know that doesn't tell much.Comment

Re: Sanyo Plasma Display Problem Dp50747
Strange thing, but first time for everything. I got a Sony DP50747 and I had it for a while. Working on it today and reading these post I found this one decided to swap out the 680 cap. I think it worked but I will never know for sure because when I powered up the TV there was a big electric snap/pop and I saw sparks come out from the edge of the panel. Blew the fuse on the X-SUS board and I replaced it but now all I get is an LED on the PS blinking 3 times. I am assuming this TV is dead.Comment

Re: Sanyo Plasma Display Problem Dp50747
Yea, the cap was put in right. There is no charring where the sparks came from so a pic wouldn't show anything. But this is the first time I seen sparks fly from the screen, and man where they strong, could have melted a screw driver.Comment

Re: Sanyo Plasma Display Problem Dp50747
I think I found my mistake, the ribbon cable at the very bottom of the screen, on the X-SUS side. The small board that comes off from the X-SUS board. The ribbon cable was loose. I think that is where the spark came from. So I removed the X-SUS board and it seems I burnt up more than 4 transistors. Being that the board is cheaper than replacing the parts I am going to order one and try it again. This is a word to everyone else, don't make this mistake.

Re: Sanyo Plasma Display Problem Dp50747
well, glad you figured out your mistake. i was thinking reversed cap or maybe shorted a buffer ribbon. never seen or heard of sparks flying off the screen.I think I found my mistake, the ribbon cable at the very bottom of the screen, on the X-SUS side.

Re: Sanyo Plasma Display Problem Dp50747
Well lets hope the TV is still good. I got the X-SUS board off of eBay for $24.00 so as soon as I receive it I will give it a try and post what happens. I have about 50 TVs I have to fix but I ran out of room so I am looking for a bigger shop or warehouse. And my frind has about 100 TVs so we might get a shop together. Of course if we get a shop we might have 2,000.Comment

Re: Sanyo Plasma Display Problem Dp50747
Well I got the replacement X-SUS board today. It was not working so I replaced that 680 cap and it made a difference. Now the TV turns on and shuts off in about 3 seconds but the screen does not light up. Going to read another post and see if I can figure out why. I guess I may have damaged my power board.Last edited by Shane711; 07-25-2015, 07:04 PM.Comment

I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down

hello,
I hope someone on this forum can assist me.
I have a panasonic TH-42PC77U plasma television.
the lower 1/2 of the screen has become flaky....in and out, then finally goes black and you can only see the top portion.
i have performed the reset to default settings quite a few times. Panasonic recommended..did not believe this would help...it didn't.
I have removed the back panel and looked around for something obvious...burn marks in a board, etc....nothing obvious...
I have read some posts that suggest the problem is related to the boards on the left... -
i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double... -

Hi. I have a problem that has been going on for some time (2-3 years). It's hard to explain what it really is. Sometimes, my computer stops playing music, stops videos (starts buffering on youtube), there is no sound in games and when I minimize the game window and return to the game there is a black screen with window borders... -
Good morning,
I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....
