W9803D4 - Arcade claw machine board

11-10-2022, 10:48 PM

Looking for the schematics for this board - its an offshoot of some Chinese board but branded for Coast to Coast entertainment

I think I narrowed down the issue I am having with the claw to a op comparator that drives a photo transistor, this seems to provide the ground used with a DPDT relay

I am in the process of trying to diagram some of the board, if no one has the schematic i'll probably post what I have traced so far

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

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.

Assuming...

More Details

TV Model - LG OLED77G1PUA
