Hi folks.. Would appreciate your help.
Hisense TV that doesn't turn on (no pic, no backlight)
Flashlight tests shows activity on the screen (Hisense ROKU) then off then again.
On the connector from PS to main, I see Vstandby (2.5 V), VAMP (16.9V) and 12V (11.86 V)
As the TV cycles, VAMP goes from 16.9 to 17.6V then back to 16.9V
Any thoughts? never seen a standby voltage as low as 2.5V. Not sure if backlight is bad, but that doesn't explain the reboot cycle - right?
