Should I test the diodes?

What about +15V (TP82) ?Comment

Measure voltage on either side of diode D480 on start up. Looking for where the SOS7 signal is coming from.Comment

Re: Panasonic TC-P50G10. 6 blinks to 7 blinks.
Getting 15v there.
That thing is super small. Hard to get a reading but it gave me 3 for a split second and then went straight to 0.
Weird new symptom. Before when I started it up it would click, SOS7 twice then turnoff. Now it just stays on and does the SOS7 over and over. Not sure if that has any meaning.Comment

Need separate readings for anode and cathode of D480 (black probe on chassis ground).
No idea about that. Usually it just repeats as it sounds like it's doing now.Weird new symptom. Before when I started it up it would click, SOS7 twice then turnoff. Now it just stays on and does the SOS7 over and over. Not sure if that has any meaning.Comment

Anode .3
Cathode .2Comment

Re: Panasonic TC-P50G10. 6 blinks to 7 blinks.
You might need to set your multimeter on peak/max hold mode to catch the SOS event. You should get 4 to 5V briefly on the cathode if you're getting SOS7. This would also show up at test point TPSOS7 obviously. If you're not getting voltage there just before the error trips then possibly the A board is misdiagnosing.Comment

Retested the Cathode and TPSOS7. Got 5v on both.Comment

So the anode?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
After all of... -
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...
