TV turns on but only the backlight lights up. No sound no picture.
Hi,
My Panasonic Viera model th-l42et5a (smart TV) switches on without issue but I get nothing but a black screen, I cannot get any menus to come up, the backlight is on. I have not heard any sounds come from the TV at all.
What I have tried so far:
Reset TV (Vol down + Menu button)= no reaction.
Unplug TV for 1 min then hold P (Menu)+ Vol down and power on= no change.
Unplugged TV for 10 min and hold power button for 1 min, then plug in= no change.
Attempt to put tv into Panel test mode by Holding Vol down+ pressing Option button three times in 2 seconds= This causes LED light to blink red/green but there is no change on display.
If I disconnect the Left ribbon cable from the ) Tcon board(leaving RHS connected) I get a half white screen on the LHS and a black screen on the RHS.
If I disconnect the Right ribbon cable and leave Left connected there is no change on screen (stays black)
Any ideas?
Es esta una buena pregunta?
