Facing TV Problems? Ask a TV Technician.
I'm reviewing your details and will reply shortly.
This is Just Answer, which is a pay for information service. We do not physically service any devices but have experience in the field and can tell you what is wrong.
That said, I need to know the following:
1) Were there any storms or power outages just prior to this occurring?
2) What pattern is that blinking light giving you (for example: 7 blinks, 7 blinks, etc.)?
Thanks for the reply. So this issue occurred without any catalyst- in other words, no storms, no power outages- out of the blue?
Are you there and able to proceed with this? I'm trying to provide you with accurate info which requires some back and forth communication.
I'm unsure why you're not able to reply, but the 5 blink code points to one of several faults in the TV (per the service manual: "A 5 blinks condition is caused by the A, C, SC, or SS board. (A>C>SC>SS)"). This generally requires repairs made to the set which are NOT cost effective on a 42" TV that can be replaced for the same price as repairs (between $300-$350 parts and labor).
However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.
