No sound means it could be a ballast issue. If there is sound, it could just be the lamp.

Replaced lamp on mitsubishi wd62527 worked for 10 minutes then shut down. Now red lamp light is on


If the red indicator light on the front of your HDTV is glowing a solid red, you should first unplug the AC cord from the wall power outlet and wait for 60 seconds before reapplying power to the HDTV.

After you turn the TV on, if it doesn't power up, try holding the power button down for at least 8 seconds. That's supposed to force a system reset. If your model has a system reset button, use that instead. Press the reset button for about 20 seconds...release it and press it again for 20 seconds, release it again and the led will blink just for a minute or two. You should now be able to turn the TV on.
If after several attempts, the HDTV has not fully powered on and the LED on the front of the HDTV is still glowing solid red, you may want to reseat the lamp.

If reseating the lamp has not resolved the issue then your next step is to order a replacement lamp.

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

Power coming in to television, but when I push the power button to turn the tv on; it does not come on.


You may have what I call the hard to turn on issue, look again in the power supply inside the set--follow power cord that goes to it and look for puffy filter caps:

Power issue, clicking noise, turns off


The clicking is the power on relay closing and opening. This happens because the TV has several built in safety systems that will detect and over voltage and over current load situation.The power supply starts up for an instant, senses and overload of either or both kinds and then the safety switches trigger a cutoff. When this happens the power supply will not start up again because another circuit called a latch keeps it disabled. By unplugging the AC cord and trying to start it again releases the latch until the failure triggers it again.
On these TVs the power supply is rarely the cause of the shutdown. Something further down inside the TV has failed. Replacing just the power supply will not fix the problem. The most common reason there would be an overload would be in the high voltage circuit that lights up the 3 CRTs, next would be the coils around the CRTs that bend the beams to make the picture. This is normal circuit aging and wearing out. Unless you are very skilled with trouble shooting TVs I would recommend having a service center look at it. An authorized JVC shop would be your best choice because they will have access to the manuals and bulletins and have probably had other similar JVC units thru their shops.

Hitachi 61UWX10B 61 in | TV will not turn on


If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on the under the screen next to the on/off switch keeps flashing, then there may be an internal fault on the set that needs to be reset.
To force the reset, try this:
  • Unplug the set and wait a few seconds
  • Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it essentially shuts down the set. The flashing LED provides the indication that a fault has been detected. Removing power to the set resets the monitoring circuitry. When plugged back in, the circuitry again does a check of the system1.gif. If it finds that there truly is a problem, then the set is shut down and the LED will again flash.

Mitsubishi VS-50705, 50 inch Rear projection TV won't turn on!


most of the time the convergance ic go bad:
but try this:
The 3 flashes of the led when you plug the unit in is the
microprocessor initializing.

This unit has an error code diagnostics.

On the front panel of the unit press and hold the INPUT and MENU
buttons at the same time and hold them down for about 5 or 6 seconds.
The unit should activate it's error code mode.

The led will flash count the number of flashes. It will then pause for
1/2 or 1 second. The led will flash again count the number of flashes.
The unit will repeate this for about 5 or 6 times.

You now have the two digit error code. The first time the led flashed
is the first number of the error code, the next time the led flashed is
the last number of the error code.

12 ----------- indicates no error
21 ------------- X-Ray Protect circuit
22 ------------ Short Protect circuit
23 ------------- Horizontal Deflection failure
24 ------------- Vertical Deflection failure


Most units give a error code "22" short protect circuit. If so check:

Q5A00
C557

If Q5A00 check bad there are other parts that have to be checked or
replaced.

If you are able to do above call a tech to service the unit
