Panasonic rear projection television systems function by taking a small image produced at the rear of the television and enlarging the information onto the TV screen. If your Panasonic television is not working properly, troubleshoot the equipment and repair any problem you are running into. Although the exact issue may vary, you can typically fix the issue on your own without the help of a television repair technician.
Things You'll Need:
- User manual
- Replacement fuse
- Phillips screwdriver
-
Open your user manual and check for the fuse type required if your fuse is blown out. Replacing the fuse is required if the TV does not appear to turn on at all. Once you know the fuse type and have it on hand (purchasable from most television repair facilities), disconnect the TV from the electrical outlet, open the rear compartment panel on the set (this may require you to remove a few Phillips screws holding the cover down), and pull out the damaged fuse. Insert the new fuse and power on the TV.
-
Turn off the TV if there is a single white or black dot on the screen. Wait a few minutes and turn the television set back on. If the dot disappears, you have a frozen pixel, which is corrected with the shut-down method. If the odd pixel remains, the screen is dead and you cannot correct the problem.
-
Check the cable connection running form any connected device to the Panasonic projection TV. If the cable is not completely inserted into the television's connection port, the TV does not receive a clear audio/video signal.
- Disconnect the TV from the local electrical outlet and let it sit turned off for a few minutes. This resets the internal hardware on the TV, correcting display and menu problems on the set. Power on the television again; it now should function correctly.
