no clicking sound by when I hold down the remote power button the light in middle bottom of tv flashes 5 times. Also by holdiing finger on TV power button at bottom right hand corner of TV the same light flashes continuously as long as I hold my finger on the power button.

the V shaped light in middle bottom of TV flashes when I hold finger on power button at bottom right hand corner of TV next to small red light.
Customer reply replied 8 months ago
working the turn on remote or power button next to red light will power up the TV sometimes. After Tv gets powered up then all is fine and all tv functions work. This TV has an power up problem.

It seems few capacitors on power supply board are failing/ defective and causing the problem. Replacement of bad capacitors or entire power supply board will fix the issue. Please click following link to view power supply board image and part number info if you have plan to do it yourself..

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.
