Re: panasonic tx42-p42x20b
6V is OK but please verify your multimeter accuracy -- check a fresh 1.5V AA it should read 1.5~1.6V.
Low battery in multimeter can cause incorrect readings with cheap meters.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonic tx42-p42x20b
That's correct. I'll try make the diagrams clearer.
Looks like your SUB3.3V is down. Let me find where that is generated and knock up a diagram.Last edited by tom66; 01-15-2014, 11:32 AM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Can you get a picture on the opposite side of IC5600?

Re: panasonic tx42-p42x20b
Whoops, sorry, my error. Do you see an IC5601? Could you get pictures top and bottom?
Meanwhile, might as well do these tests on IC5600 (they could be useful.)Attached FilesPlease do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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... -
All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
