Facing TV Problems? Ask a TV Technician.
Hello, Sorry you're having problems. Generally that crackling indicates a hard ware failure (or short circuit) has occurred in the set (Sustain boards, power supply board, or even the screen itself). However that blinking red light is significant - it blinks a code. In order for me to tell you what is causing this, can you please get me the specific blink code the set is giving you (for example: 7 blinks, 7 blinks, etc.)?
I'm unsure why you're unable to reply, but are you at the set and can you check that blinking pattern, or are you not able?
Generally the common issues with this set (and other Panasonic Plasma sets) are failing Sustain boards, a faulty Power Supply, or in some rare cases the Plasma display panel itself. The average cost for repairs on this model is in the $350-$450 range, and a brand new 50" LED Smart TV starts at around $500 - so repairs are generally not cost effective.
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.
