Re: Panasonic th-p42x10z
Nick has very kindly let me try his power supply pcba and I'm pleased to confirm that the picture is now completely normal. Vsus and Vda are stable under load unlike my pcba where they seemed to sag. So am now confident that this was causing the picture issues.
Unfortunately this doesn't help Nick with his set though.
Kind regards

Re: Panasonic th-p42x10z
tw2005, we appreciate the help and the time that you give. Who would think that it wouldn't show an error with that drop in voltage. My thoughts without investigating are that either the Power board is saying all is fine or that this error isn't being checked for after the display is turned on. Probably the first is most likely and is part of the board fault that it thinks it's in regulation with load when it's not.
Nick hasn't given up on his yet, he is just busy with other things at the moment. Kind regards

Re: Panasonic th-p42x10z
yes really appreciated all the advice and feedback you gave us tw2005,at least we fixed one problem.
Now this maybe a silly question but was just reading on another forum about a panasonic plasma with 6 blinks when plugged into an extension cord but turning on when plugged straight into the wall socket... now do you really think this would make a difference because i just realised everytime i plugged my tv in it was plugged into an extension cord and i never tried it into just the plug. hmmm not really hopeful but i guess it could be possible..Comment

Re: Panasonic th-p42x10z
Well I gave up on my original tv for a while but i have just managed to get hold of a second tv of same model..This one had the 12 flashes of led when powered on so changed my A board over and to my surprise it goes lol just not 100% the screen has 2 little vertical lines one each side of panel so now i hope its one of the spare boards i have and not the panel itself...Comment

Re: Panasonic th-p42x10z
well this tv went for about 5 mins with the 2 lines on the screen and not sure what i did if i just unplugged the wrong cable or something but when i turned it back on i was back to the same 6 blinks that i had with the other tv so after 9 months of this tv sitting in the spare room in bits i think i ready to give up. I think i will take the boards out and try to sell them since i believe its the panels that are the problem...lesson learnt dont play with plasmas lol
Anyone interested in the boards?Comment

Re: Panasonic th-p42x10z
Been heree before. Clip sos6 from SS output to bottom panel driver boards. It's an erroneous error. Panasonic's are very temperamental with vertical VA buffer shorts.Did I leave the soldering iron on?Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.
The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.
I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was... -
Hello, I've had this TV for 3 years, 2 years ago it stopped working signaling 12 Blinks, SOUND_SOS according to the service manual.
It has no VSUS or VDAT, and P15V has 1.0V instead, the same 15V goes to A board. F15V is ok and other main voltage rails.
It seems the power supply is defective, since unplugging D20 ribbon cable that goes from D-board to SC-board makes the behavior change, the TV stays on, there's no image nor VSUS, but 15V reads 2.4V, high enough to not trip the SOS 12 blinks, so it stays on, fans do not spin but I left it 2 hours, green led lit up...
