My panasonic PT-56WX51CE rear projection will not turn on. Fuses where ok.

When I hit the power "on" using the remote control, there's a "click" sound that comes from the TV, but no sound or picture. It doesn't work when I tried the power button on the TV.

The click sound tells us that the microprocessor circuit is working and can be eliminated. The horizontal is the number one suspect. It could be shorted. If it is, then, the high voltage transformer or the focus block become a suspect as well. The voltages on the secondary of the power supply is the next place to check. If they are all there, then, you can rule out the power supply. If the voltages are missing, then, the regulator circuit is where the problem is. If only one voltage is missing, then, the the secondary has an issue and the circuit it supplies probably has a short. Good Luck

Is Worth Fixing Panasonic PT-50LC13-K Rear Projector TV

most likely a bad mainboard or bad caps in the power supply. Borderline on the repair-ability. I would check Shopjimmy.com to see if used parts are available. If they are it may be worth it.

Panasonic PT-47wx53 just shut off

Your convergence ICs have failed. Thats what causes the led to blink three times. The PT53WX53 convergence repair kit from www.tvrepairworld.com will usually repair that issue. The kit also contains the CD with detailed repair instructions.

Panasonic PT-50DL54; turns on and then in 5-10 seconds turns off. Replaced bulb, no help. Cleaned it out, no help. Any ideas?

It does sound like a heat related issue. What did you clean? I removed the back panel. Use compressed air to blow out all the dust from the components inside. Do not blow into the fan on the right.
I also replaced the batteries on the remote with new Alkaline batteries. Do not use rechargeable. Weak batteries can cause the remote to send POWER OFF command to the set.

Reseting The Projection Lamp Hours Meter

If you need the original remote, you can order the original Panasonic replacement remote control for this model (PT-50LC14) from a major Panasonic parts distributor at the link below:

Panasonic PT-50LC14 Replacement Part Remote Control

Sometimes there's a way to reset the counter by mashing certain keys on the TV itself in a sequence, but if your owner's manual doesn't specify this option, then you may have to get the original replacement remote to be able to reset it.

How to reset the meter of lamp

You need to have your Panasonic remote.
1. Make sure the power cord is plugged into a properly grounded outlet and turn on the set with the power button on the projection unit or the remote control.

2. While holding down the (VOL -) key on the projection unit press the PIP or SPLIT key at the same time. Hold it for longer than 5 Seconds. The PIP or SPLIT key is model specific:

PIP for Models:
PT-50LC13/PT-60LC13/PT-50LCX63/
PT-60LCX63/PT-43LCX64/
PT-50LCX64/PT-60LCX64

SPLIT for Models:
PT-43LC14/PT-50LC14/PT-60LC14

3. When the unit resets the lamp timer it will display a screen on the TV indicating it was reset to zero. You press recall on the remote to exit.
