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

by Tynan Dill

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.

Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock

by sam_sam_sam

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

Help Needed with LG TV Power Board Repair (Model No: OLED 55EG9A7V, Board No: LGP55B7-170P)

by justice171
Hi everyone,

I'm currently troubleshooting an issue with my LG TV (Model No: OLED 55EG9A7V, Power Board No: LGP55B7-170P) and would appreciate your guidance.

When I press the power button, the standby LED flickers three times, and the relay clicks multiple times before stopping. During this time, I measured the voltages:
- Over P201: I receive all the correct voltages.
- Over P202: I only receive 12V, but the 24V is missing.
The 24V is used to power the display board (Tcon) via the flex cable, but even when I disconnect the flex cable, the 24V is still not present....
