Hello, I need bit more info about TV to troubleshoot the problem.- Can you please get me the model number written on back of TV?- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?Thanks.
Customer: replied 1 year ago.
The model no. is TX-P42GT30B.
There are several video sources plus a sky box connected to the TV. The screen won't turn on for any function.
Expert:  Shahid replied 1 year ago.
OK, does power light on TV lit or blink when push power button to turn On the TV?
Customer: replied 1 year ago.
Yes. It will flash green several times and then goes back to red
Expert:  Shahid replied 1 year ago.
OK and red light stays steady and doesn't blink, is this correct?If so, have you tried to unplug TV power cord from wall outlet for 10 minutes to reset, replug back in and check?If not yet, can you try it now and reply back with the result?Thanks.
Customer: replied 1 year ago.
No the red light is blinking
Expert:  Shahid replied 1 year ago.
So red light is blinking?If so then count how many times it blinks then pause and repeats the same blink pattern?
Customer: replied 1 year ago.
I'm just trying the ten minute power off
Expert:  Shahid replied 1 year ago.
OK, please take your time.
Customer: replied 1 year ago.
blinks seven times then pauses.
Expert:  Shahid replied 1 year ago.
ah OK, 7 times blinks indicates SC Board failure in TV and some times power supply board also went out due to short in SC board, it needs further troubleshooting inside TV with multimeter to determine what board is bad to replace it, this kind of work should be done by TV tech to avoid any electric shock as both boards work on high volts. I'm sorry it is not any wrong settings issue but hardware failure and TV needs service by TV tech.I trust my input will help you out. Please feel free to respond if you have any additional questions.A positive rating to answer would be greatly appreciated, please click on smiley face/star on this page then click submit/finish button so I can get credit on website for my work.
