MITSUBISHI WS55907 Diamond 1080 TV bought in 2000 was powered off, unplugged, for a year. Turned the set on with remote last night and worked fine, had very crisp picture.


Your TV was waiting between 2000 and now to suffer power supply failure. It is very frustrating to go from everything working perfectly to nothing.

We just got a panasonic pt52lcx15 tv from a neighbor the tv works fine turns on has sound etc for about five minuets then powers down and the red lamp indicator flashes for about 1 time every 5 seconds


Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

Have a proscan ps50700 that wont show the picture, will turn on but turns itself right back off. what could it be


TV Doesn't Turn On
  • Your RCA rear projection TV may not turn on from time to time for several reasons. First, check that the power cord is plugged into a working power outlet. Check that the outlet is receiving electricity by plugging a different device into the outlet. If the other device doesn't work, you may need to replace a fuse or reset a circuit breaker in your home.

    If you tried using the remote control to turn on the TV, press the "Power" button on the front of the TV. You may have a problem with the remote control if the TV turns on.

    If you tried using the front control panels and haven't tried the remote, press the "Power" button on the remote control. The television controls are blocked if the TV turns on with the remote. To unlock the controls, open the "Parental Control" menu and remove the check mark next to "Front Panel Block."

    Finally, your TV may be performing a diagnostic check. These checks are used to find any errors in your TV. Wait a few minutes before trying to turn on the TV again.

TV Turns Off By Itself
  • You may find that your RCA TV turns off by itself on occasion. This is often because the "Sleep Timer" feature was enabled. This feature allows you to place a timer on the television that will turn it off after a specific amount of time has passed. The feature allows you to save on your energy bill and extend the life of your television.

    If the "Sleep Timer" wasn't set, the television may have detected a power surge in your home and shut off automatically to protect the components of the television. Wait at least 30 seconds before turning the TV on again.

    Finally, if you suspect the television is turning off for a reason other than a power surge, unplug the television and let it sit for at least 10 minutes. This will clear any errors in the television. After 10 minutes, plug the television back into the outlet and resume normal use.

  • Blank Screen
  • A blank screen on an RCA rear projection television is usually caused by a loose connection or an incorrect setting. Check that the coaxial connection on the back of the television is secure or, if you're using an external device such as a DVD player, the video cables are secure. Press the "Ant/Cable" button to switch between tuners if you are watching television, or the "Input" button to switch between input channels if you're watching something from an external device.

TV Wont turn on after lighting storm. I have tried to; unplug and plug back in. Unplug it for 24 hrs. Try different outlets. Look at the build, looks fine.


The TV circuitry is designed to protect from power surges. The fuse on the power supply may be blown, or the power supply itself could have taken a hit. I would try to check the fuse first and then if it turns back on... it did it's job!

Good luck! and let me know what happens!

Turn on tv and standby light flashes 6 times


The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue.

Follow the steps below to perform a power reset:
  1. Turn off the television.
  2. Unplug the TV power cord from the electrical outlet.
  3. Let the TV remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the TV 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 TV.
  5. Turn on the television. NOTE: If the TV does not turn on immediately, the fan may need to finish its cycle. This is part of the cooling process for some projection TVs and is normal operation. After the fan turns off, attempt to turn the TV on again.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required . Please note the number of times the STANDBY light flashes and relay that information to the service center.

No picture or sound?? status light flashes in four blinking intervals. I was told it could possibly be the lamp it has never been replaced.


The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
  1. Turn off the television.IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet.NOTE: 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.
  5. Turn on the television.

Sony Grand WEGA KF42WE610 42" turns on and off


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.

Please make sure that the videos sources are connected properly to the TV.

Try Power Resetting the TV.

Please disconnect the power cord from the wall outlet (for approximately 1 minute), then reconnect the power cord and check whether the issue is resolved.

Also try connecting the TV to a different wall outlet and check if that helps.

No power


Check to make sure that the lamp access cover is installed properly. There is a safety switch that prevents the tv from powering on while this cover is off. This may be true especially if the lamp was serviced recently or the tv was moved, power cord pulled etc.

I have a Panasonic CT-26WX15N TV that was working fine when turned off and now it won't turn back on. I have it plugged into a surge protector and all the other electronic devices work fine. I also...


first things first- check the main power fuse; remove the 9 silver screws from the back of the unit, slide off the rear cover, and look at the main board right next to the power cord connection. There's a small, 6.3 amp fuse. Take a look at it; if it's blown... replace it.
