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.

Hi,
The lamp has already a resistance which is sense by the processor and made the unit a subsequent shutdown. It will produce an overload to the ballast board which is detected by the processor. Replace it with new one and your unit will back to normal again.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Panasonic PT-53TWD63, TV will not turn on, Red power light blinks


It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.

Hi, The problem comes from what we would call a "contaminated circuit board". The board has to be replaced or repaired. Since the Television is less then a year old, I am sure the manufacturer has a 90-day parts and 1-year labor warranty policy. Contact the manufacturer would be the cheapest method of replacing the unit. Thanks, Mike H.

Samsung HCM4215W,shuts off.


Sounds like a short in the power wire, it takes about 10 to 15 minutes to warm up then shorts out and when it cools down you can watch for 10 to 15 more minutes before it shuts off again, you need to take it in and have the powercord replaced because this is very hard to do from home and one mistake can make the whole tv not work.
