Question about Panasonic PT-43LC14 43" Rear Projection HDTV

1 Answer

Tv won't turn on

The power light is solid red. When I push the button it will not come on. My tv is connected to a JVC receiver. It is on, the cable is on, I have sound but the power light on the TV will not turn green. The lamp indicator light is not on, the temp light is not on. I can't turn in on manually or with the remote.

repair technician and he confirmed that the Ballast is defective and causes the bulbs to blow out prematurely in many of the sets manufactured in '03/'04. BTW. Panny will pay to replace the ballast, if defective, even out of warranty.

Why would JVC 8010 optic digital randomly malfunction?


I don't know if this helps but, if you have your bluray hooked directly to your tv some times TVs can have issues sending the proper channel to audio out to the receiver. You should always connect your bluray and other devices directly to your receiver.

if that's not the case,
Try turning the tv speakers back on, test the bluray hooked directly to the tv and see if things work flawlessly just with the tv and bluray.

If they don't there may be something just wrong with the cables.

If they do work flawlessly then there may be something wrong with the receiver.

If you already had your bluray connected to the receiver, I would still try direct to tv test and swapping cables.

The randomness leads me to think cables. But you can rule them out by testing directly to TV.

I hope that helps

TV does not turn on? (Relay problem?)


The power supply could be failing intermittently. That's why it sometimes works and sometimes doesn't. Also, the relay could be erratic.

I bought a universal jumbo remote and i followed instructions i to program it to my Jvc tv but it does not work can u help?


Make sure you try every code in the list for your JVC TV.
The codes for your Jumbo Universal Remote to control a JVC television are 013, 054, 055, 060, 065, 067, and 089.

To program your remote by entering a code, follow these steps:

  1. Turn on your TV.
  2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
  3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
  4. Enter the first set of 3-digit codes from the list. The LED will blink once every keypress. After the 3rd digit, the red LED will turn off indicating that the code was recognized for the device. If the code was not compatible, the LED will flash several times and you need to return to step 2 to try that code again or to try the next code in the list.
  5. After the LED has turned off, aim the remote at the TV and press ON/OFF. If the device turns off, you have used the correct code and the remote was successfully programed. If the device does not power off, return to step 2 and try again with the next code in the list.
To have the remote try each TV code it knows one at a time, follow these steps:
  1. Turn on your TV.
  2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
  3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
  4. Press the ON/OFF button slowly and repeatedly until the TV turns off. The LED will blink once each time you press the ON/OFF button.
  5. Once the TV turns off, press the ENTER button to store the code and the LED will turn off.

I hope that helps.

TV turned off itself and timer light (red) keeps blinking


The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

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 , startingthe flashing light.


If you are in situation one, then theTV 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.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.
