Question about Televison & Video

1 Answer

Whenever there are flashes on the screen, the TV will switch off and there is no power light on. So far the only fix has been to unplug it for 5-10 minutes. I would like to know what the problem is so the TV will stop shutting off.

PANASONIC VIERA TX55as802b will not switch on red power/standby light blinking once every 3-4 seconds have been told its the screen and it cant be repaired can anyone confirm this or help.thanx


The manual says nothing about the power light flashing at that rate. Unless an expert tells you that's the specific indication for a failed screen, I wouldn't believe it. Most TV's will give you sound even if the display has failed.

Try resetting it by unplugging and waiting 60 seconds before plugging it back in.
If that doesn't work, most likely the power supply board needs to be replaced. Or possibly the T-con board.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

KDF 50E2000 WONT POWER UP POWER LITE BLINKS RED 3 TIMES THANKS


Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.

If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.


Thanks for using Fixya.

Tv wont turn on


Green light of death, capacitors have to be replaced but it probably wont fix it anyways. Once this happens the TV is completely useless.

No POWER


How many times does the POWER led flash per second? (Dont worry about the OPC).

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)

Flashing LED
<< Back to Quick Fixes Page
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 system. If it finds that there truly is a problem, then the set is shut down and the LED will again flash.

Screen does not switch on, mode light flashes orange


Need to remove the Input module circuit box from the bottom of the center and wait for few minutes before putting it back.

This will reset the system from this persistant power off problem.

Best way to prevent it from happening again is to manually switch of the power switch before doing any powering off and on. Most commonly happens during a power failure and power coming back on with the switch in the on position.
