Pt-47WX42 Need To Adjust Color

I had this problem a couple years ago and it was still under service-warranty from where we bought it. The service tech removed the front cover (The part with the cloth, similar to a speaker cover) I don't see any screws so I'm wondering if I should just rip keep pulling till it comes off. Anyone know the proper way of doing this?

Panasonic pt-47wx42 5 blinking power lights

5 blinks is short protection, it means a short on the 140 volt line coming from the set's power supply.

Most likely is the horizontal output transistor is bad.

Let me know if you want to know how to get at it and test it.

The set has a light box that contains everything that can be removed for this kind of service.

I am very familiar with this set and have fixed hundreds of them.

I have a panasonic pt-47wx42 a red shadow of the pick just showed up looks like a double???

If you have gone into the customer menu and CONVERGENCE is skewed and will not adjust:

One or both of the two STK-392-110 convergence chips that this set uses are bad.

The chips are about 2 1 /2 inches wide by 1 1/2 inches tall and are black in color. They are mounted on metal heat sinks2.gif with fins and are side by side--they will have the Stk-392-110 number printed on them in white letters.

If you locate them take a good look at all the light blue resistors in front of them--most are marked 2.2 ohms---look for any that are white or discolored in the middle---if you find one or more YOU HAVE FOUND YOUR PROBLEM.

BOTH chips and any bad resistors need to be replaced and the set adjusted. If you can do this repair you can save a lot of money as you can buy both chips (a pair) on Ebay for about 12 dollars plus shipping2.gif.

I have start to finish instructions for this repair on this type of set.

If you cannot do this repair yourself, shop around your area--most shops charge 300-400 for this kind of repair--I do them here for 200-250 and have done hundreds of them.

If they say it has to go to the shop--keep looking as any good tech can do this repair in your home in about 1 hour.

Pt-52lcx65 52 in.

call panasonic customer a claim....problem is most likely that the eprom needs to be reflashed.....i contacted them several weeks ago, told them my problem which was 5 baseball sized colored spots, 1 red, 2 blue and 2 green. they had me perform a couple of tests using a dvd. when i reported the results they set up a service call with a local authorized repair shop. results were amazing. reflashing the eprom took about 4-6 minutes. in addition my brilliant color returned to the set as well as another problem of neon images going away. this was paid for by panasonic. my set was 2 years over warranty. panasonic has issued a service bulletin on this and are backing up these units.
hope this helps, i am quite satisfied with what was done.

Television has picture but with a ghost images and with a rainbow of color above the screen. I had bought this television a year ago. At a NATIONAL RENT-TO-OWN. IT SHOULD STILL BE UNDER WARRANTY!

This set has a convergence problem. This could be as simple as bad connections at the convergence ICs or defective ICs. In either case, the set should be under warranty and be repaired relatively simply. DO NOT open up the set as that would void hte warranty. Request warranty service and let us know if you need further assistance.
