Facing TV Problems? Ask a TV Technician.
Does power light flash in specific pattern like 2 fast flash then 2 slow flash, pauses for few seconds and repeats the blink pattern?
Please count/check the blink pattern and reply with the info as it is an error code that will tell the problem section in TV.
OK, this error code (1 fast - 1 slow) indicates lamp failure that means backlight system problem in TV, we can try few things to determine what is causing the problem to get it resolved unless we have bad screen in TV.
As first thing, unplug TV power cord from wall for 10 minutes to reset, replug back in, turn TV On and check.
If problem persist then while holding down the “VOL Down” and “INPUT” buttons on TV at a time, plug in the AC cord of the TV to turn on the power. Does screen show letter 'K'?
OK, did the screen glow/ showed backlight or any graphics appear while TV stay On for a while?
OK, please unplug TV power cord from wall outlet for a minute, while holding down the “VOL Down” and “INPUT” buttons on TV at same time, plug in the power cord of the TV.
Does screen show letter 'K'?
OK, since Sharp logo screen appears for a while that means backlight system is working and main board turns it Off for some internal reason, swapping the main board in TV will help to resolve the issue.
