Re: LG 60PA5500 No VSC or VY Voltage
Thanks, I'll do a little more checking.

Re: LG 60PA5500 No VSC or VY Voltage
Try installing just the lower buffer board leaving the upper buffer board disconnected and see if you have VSC. This model TV is plagued with the plastic bezel surround eating through the top scan ribbon cable on the panel. Intern this loads down in shorts out the very top IC on the upper buffer boardDid I leave the soldering iron on?Comment

Re: LG 60PA5500 No VSC or VY Voltage
I believe this model shuts off from lack of current draw through power supply if neither buffer board is connectedDid 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 all,
this unit comes from a samsumg LCD TV LE32C530F1W which stopped working after making a strong noise like something was exploded inside of it.
I opened it and found that fuse FP801S was blown, capacitor CP814 was completely disintegrated and MOSFET QP801S was shorted.
I replaced all of them and instead of the fuse I connected a 100 Watt bulb. Then, without connecting it to other TV boards, I switched it on, but the bulb begun to blink.
I thought that maybe the bulb was somehow interfering with the normal operation of the power supply, so I replaced it with a fuse,... -

I have an LG plasma that after reading through a bunch of posts and doing some testing I believe has a bad YSUS board. The problem is that that doesn't make sense to me for some of the symptoms. The problem started yesterday. While watching a movie the TV just shut down like I pressed power. I have it hooked to a PC and use RS232 to turn it off and on so I thought maybe something had glitched there. I turned it back on and finished the movie with no problems. The same thing happened today so I checked logs to see if something in the control glitched and sent an off command but it didn't, After... -
i have Gigabyte Z490 Gaming X Motherboard .it has a power on no display fault .. no vcore voltage and debug led stuck CPU LED .

VPP 2.5 OK
But No Core Voltage
and i want to this vrm ic datasheet or pinout (ISL69269)
anyone have this ic pinout voltages?...
