These sets are notorious for bad inverter boards and bad video processor boards.Sharp is well aware of the problem,and will fix the units if you push the issue.

My panasonic tv model TC32LX85 N has self check and wont go away?

To Exit Self-check Screen
  • Press and Hold Power button on the TV for 5 seconds [or] disconnect the AC cord from wall socket.
TV volume down and OK on the remote only does a basic IC self check. It do not rest the TV. It do not clear channel programmed settings, picture settings, channel labels, lock settings or password. Using this method, it shows the units' firmware version [Peaks 1.050 and GenX 1.00] and it checks the IC communications only. This is more useful to identify the firmware version, without having to decode the info in the setup menu about version/screen.

  • To make a reset to TV, turn it ON while pressing the [Volume-ve] button on the main unit, and press the 'Menu' button on the remote control for more than 3 seconds. The self check menu appear on the screen. Then disconnect the AC cord from the wall outlet. [ALL PROGRAMMED PARAMETERS WILL BE ERASED]

Tv wont turn on

Hello Charliebigwh, hi technically your monitor's power supply has a problem, this is either your switching regulator does not work or there is a short in that section, If you want to do it your self, need to replace all large value, and or high voltage capacitors(especially the capacitors with its top is bubbly), need also to replace the switching IC, and power transistor.

Have it checked by a technician if you cannot do the work.

My 42 inch LG plasma turns on and off repeatedly when I try to turn it on. happened a few times before when tv was working fine, now it wont turn on at all. I have to unplug tv to get it to stop turning on...

Theres a short between the start-up processor signal on the interface board and power supply. It keeps sending the same start-byte over and over again to the power board. This could also be a DC high voltage shutdown on the power board its self. Now the tv is in protection mode to prevent further damage. Get it serviced at your local repair center. If its under warranty take it back.

Hitachi 50v500 tv lamp light blinking no picture

I have one of these units, if the light is blinking and no picture as you have stated then you will need to replace the bulb in the unit. it is contained in the front of the unit behind the front panel on the right, you would remove the front panel after unplugging the unit, remove the single screw and pull out the box. replace it and then reverse the proces. the bulbs can be obtained for about $130.00 to $200.00 depending on where you get it from. Shop around.

Lcd tv shuts down by its self

All you need to do is remove the back cover, then remove the metal cover that covered the power supply. Watch tv w/o cover, it won't shut down again. Try it and post here if it works.
