LG 50PK590 - three clicks and steady red light, won't turn on.
Hi all,
I've got a LG 50PK590 plasma TV which upon plugging in will click three times and the red LED in the corner will come on and stay on, the TV however doesn't come on (no humming, sound, video, etc.) and using the touch controls or the remote does nothing. On exceptionally odd occasions, the TV will come on and work normally when plugged in and will last about 5 minutes before going back to off and unresponsive.
I've got the back off of it and none of the caps stand out as visibly buggered, I've also tested the three resistors in the corner of the power board which all show around 10 ohms. When powered, disconnecting and reconnecting the main board from the power board will recreate the three clicks which seem to be coming from the power board. I've read this can be down to a bad voltage regulator?
Any insight is much appreciated.
Thanks
