We had our tv going on a year and were watching it when we heard a small pop noise and the picture went out. the tv was still turned on but about 5 minutes later there was a second louder pop and the power went out of the tv. we tried turning it back on but nothing happened. is this a repairable problem?

First of all go into the audio menu settings and turn off the "surround" feature off and that should fix the voices/music differences. Does the craking sound appear while watching any sorce such as cable box,sat rcvr or DVD player? If not isolate it to that input and maybe that device is giving the problem.

Just hold down the input button on the right side of the tv. This is the bottom one. So,
With the tv off,
press and hold the bottom button (input)
when the tv turns on, and you see the input menu
release and press the button to put the tv into a mode that works!

Had someone come to me with the same thing asking about the
the cost to replace the LCD screen. This was for a 46 inch JVC (3 months old).
The cost of the screen...$2600 plus a $500 core charge, plus a minimum of $45
to ship it. Keep in mind the guy paid $900 for the whole set new.
If you decide to get another set you might consider getting one that is the same model
as the one you already have and save the other set for parts.

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem
