This is a fairly new 4K TV. When the power button is pressed, the front LED turns on but there is no backlight. I had a cracked screen of this model but sold all the boards. Doh!
Probing the main power supply connector, all voltages look good though 12V is really 19V. PS-On comes on at 3.6V but BL-ON doesn't. Main board is getting power.
Searching the main board on Shopjimmy indicates an EEPROM is available for this model with the symptom no backlights. There is an associated video with a different model but similar main board showing location of U202 (back side of the board). Tried freezing and it didn't turn on. Ordered eeprom from their ebay store since it is free shipping versus their website direct.
