Re: panasonic tx42-p42x20b
must be labelled different to the UK flat TV picture but the ME-TP3 could be the clue as the rev I was expecting was ME.
They can have white stickers with the number or a 2 letter suffix stamped on the PCB or a table printed into the board listing all the suffixes and some jumpers which indicate what suffix it is.
We have 3 sources listing an A for this model as the same including 1 UK source so it should be correct or upload some hi res shots of it top and bottom using advanced, manage attachments , max res is 2000 x 2000.
Anyway do yo have a meter to check anything?
i have the Aussie model TH-P42X20A, pretty much the same, the A board can cause SOS10, I caused mine to do it and it was the cabling was corroded and shorted out the A - SN board ribbom SN20. I fixed it by replacing the 2 buffer Ics on the A talk to the SN and the ribbon also sends 5v to the SN board, so P5v shorted tripped the SOS10 at the A.
I'd be tempted to check for shorted Vsus at either SN2 or SS11 first.Last edited by tw2005; 01-05-2014, 06:32 PM.Comment

So several things to try.
Disconnect 3 white ribbons at A, Disconnect SN2 (SN board LHS), SS11(SS rhs) and p35(PSU , feeds the C boards bottom of panel)
Power on.
Reconnect
disconnect SS11, see if SOS10 clears.
reconnect
disconnect SN2, SN3 and Sn20
Let me know the results
edit; don't reconnect straight away due to residual voltages on P2,P11 & P35, let it stand for 5 minutes, should really check with a meter. I've spiked those bottom buffers (c boards but a Samsung) and destroyed the Ics on them which means dead panel, no repair.Last edited by tw2005; 01-05-2014, 06:10 PM.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI 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.

by m1ch43lzmHi, 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... -
by sam_sam_samI 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

by canadaboy25I 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... -

Having said that I come to the gist of my post on the forum as the title suggests.
