    This is not a DLP screen. It's a plasma screen, if that makes a difference.

If this is a DLP set the lamp is bad. You can find replacements on the web. Be very careful not to touch the lamp before you install it.

    Yes it makes a difference! You obviously don't appreciate my help so call a repairman. It shouldn't cost you more than 4-5 hundred dollars.

Jake I have a 52 inch Panasonic plasma tv that will only run the fans for a few seconds and shutdown red light blinks 10 times and repeats.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen A2 slightly.

Set will not power on.. Blinks red LED 8 times


It's a power supply related problem.
The flashing 8 times is a trouble code. A Service Manual for your TV model will have the info on the codes. It could be a bad capacitor or a transformer on the power supply board.If you have some electronic experience, you can find a Service Manual for your TV over the internet. Cost about under $20.

Power LED blinks red


it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea
