Question about Panasonic PT-53WX53 53" Rear Projection HDTV-Ready Television

Open Question

Panasonic projection TV front LED blinks 5 times

My panasonic RP TV developed a problem where it was powering on but just had a small rainbow of colors in the middle of the screen and rest of the screen was dark. I replaced the vertical IC (IC451) and also the two convergence ICs. The convergence resistors are also fine. Now when I turn on my TV, it produces a ticking sound and then whines as if the HV is trying to come up. But then it cuts off, the front LED starts blinking 5 times and repeatedly indicating faulty IC4511. I have also replaced the flyback and the HOT but the symptoms remain the same. I also do not see any apparent problem with the caps etc on D-board. What could be wrong with the set? Can anybody help? The chassis is AP-825. Thanks

    IC-4511 is the main processor located on DG board which is mounted on the A board. It is not user replaceable because of very fine machine soldering. The number on DG board is A13315. I did not replace it as yet because I think there may be some other problem that is coming up as a main processor fault. Anyways, the DG board also costs more than the TV is worth. Any other hints?

SOURCE: Convergence Resistors

Can you check that location number again The parts list doesnt list a capacitor with that location number. Is the item a resistor or a capacitor ? Let me know the other site I work at has full service manuals with part numbers and specs in them. I will be able to tell you the specs on your part

3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures.

SOURCE: I need to identify the

The resistor you see is a 2.2 ohm 2 watt resistor and is part of the convergence circuitry. I would replace R7011. 7012, 7013, 7014, 7015 & 7016 (all the same value) and the 2 STK392-110 Convergence ICs. This should fix your problem. You can find kits on-line for around $45 with the IC's and resistors together.

Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.
