Question about Televison & Video
Haven't been used in a couple years but worked perfectly fine yesterday and today it wont turn on at all. There was a lot of dust in the back so i used a blow off duster to remove all the dust and still didn't work, unplugged the power cord and plugged it back in and still nothing. Opened the back to check if any parts were out of place and everything was fine.
The power indicator should blink 1-5 blinks when it wont power up. If you let me know how many blinks your getting I can assist with the problem.

5 blinks is telling you that IC4511 on the DG board is faulty. This is not serviceable you will need a new DG board the part number of that board is TNP2AA126

Three blinks is short protection. 98% of the time in this model it means one of the two convergence IC chips has shorted and is bad.
There is a easy way for you to confirm this: inside the set with it unplugged look for the two STK-392-110 chips this set uses--they are black in color--2 1/2 wide and 1 1/2 tall and on metal heat sinks with fins side by side.
They will have the STK-392-110 NUMBER printed on the front of them in white letters. In front of them are about a dozen light blue colored resistors--most will be marked 2.2 ohms---look to see if ANY of them are discolored or slightly white in the middle--if you find even ONE discolored you have found your problem.
Both chips and any bad resistors need to be replaced and the set adjusted with the Panasonic remote.
I have START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET.
The instructions tell you all that you will need to do the repair and I can tell you the best seller on Ebay to buy the chips from. This repair takes about a hour or so to do----I have done hundreds of them.
You can buy all the parts for this repair for less than 30 dollars--shops are going to get 300 or more for this repair.
