Hi All, hope someone can assist. I have an arcade machine with a 55 inch LCD screen that's in need of repair. When I acquired it the screen did power on briefly and during this time the source and volume controls were all screwy and did not respond to the buttons as expected. It then switched off and did not power back on. Now only the red standby light is on when I power it.

All the parts are modular therefore could potentially be replaced with universal parts as I'm not restricted by a TV housing. I prefer to repair as the screen mounts are custom and the arcade trimming has been built to suit.

The component information I have gathered so far:

Screen is AUO (AU Optics) Model T546HW01
Power Board AYP449901 Rev 1.0
Mainboard Top-Tech 6M16 V2.0-C
TCon Board PL.MS6M20S.2B 9515

I suspect it's the Mainboard but not experienced with TV repairs at all.

Left lower corner on power board appears toasted. Right edge has connectors with voltages and switching labeled.

Tcon is NOT shown in your pix. Quick research leads HERE

Sorry - forgot to mention I did check the voltage output with a multimeter from the power board and did match what was printed.
