PN64E533D2:Powers down

08-12-2019, 09:54 AM

Hey guys need some help with this one. I've changed the three caps on the
y sustain board. If cable between the y sustain and the control board is removed the svc_vs,vscan as well as the voltages on the x board stay up.
If cable is reconnected voltages come up briefly and go down. Never see the
screen prime. What am i missing thanks

Thanks for the reply i saw the video before and was looking for a shorted cap and did not
see any. I will like the video suggest change all the capacitors in question. Just curious as to what is missing voltage wise which would cause shutdown.

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.

My first attempt at board repair - Asus Prime X670-P

LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update

More Details

TV Model - LG OLED77G1PUA
