The tv wont come on it just has a red light blinking 3 times where it turns on

thats the error code for the convergence ICs. Replace both STK392-110 Convergence Ics and the 2.2 ohm resistors. You can get the Panasonic rear projection Convergence repair kit #1 at the following link which contains the two ICs and all six resistors plus step by step instructions with pictures so you can do the repair yourself.

5 blinks indicates that the micro-processor IC on the DG board has failed. A component level repair is usually not possible in cases like this and the board has to be replaced to resolve the problem. Board costs about 200-300$. Let me know if you wish to replace it yourself .

Hello,
The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.
I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
Good luck.
one or more lights on the front should blink an error code
Set likely has either a problem with its power supply board or something is pulling voltages there down--
Power supply board is the place to begin
