Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

I have determined that it is my green bulb that is bad, because it also controls a lot of the black/white picures, thus that I believe it is out this is causing the darkness. I went through all of the convergences through set up and altered/adjusted all the options in picture, not much changed other than the brightness of the pictures which at least makes it somewhat watchable. Have called a tech to replace bulb. Will let you know if it is anything else, but I must say for a "girl" I am getting very good at assessing a lot of mechanical issues :)

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.

In this day and age of low cost LCD and Plasma TVs I would say about $300.00
You can buy a newer better TV (same size for a little more and get a warranty with it!) These are now considered stone age because of the space they take up!

If the CRT Projection television has several colors or one that arent lining up, if due to an impact - you may have a broken mirror, if just happened all by itsself it may be a convergence issue, either issue is repairable, probably for around $400-$500. I dont recommend taking a set like that into the shop as sometimes transport can break/crack a mirror or throw convergence off.

Can you explain the problem in more detail..

Panasonic... | Answered on Sep 01, 2008


English please..

Panasonic... | Answered on Aug 29, 2008


I found the chips easy to replace, but time-comsuming due to the number of pins involved. I woudn't want to try it if I'd not had prior experience with soldering.

Still no response to the original question though. With 2 replaced STK392s, red is still not moving in horizontal alignment. What gives?

Panasonic... | Answered on Aug 27, 2008


The problem you are seeing is a convergence problem. This is a common problem and is fixed either by resoldering bad connections on the convergence ICs or replacing the ICs. These are large black ICs attached to a heatsink and are marked STKxxx. Try resoldering the pins on these ICs first.

Does the led blink when you press power? If so please let me know the number of blinks as that is an error code.
