    your tv is the dptv 300 series chassis

    your model uses (2) STK392-110 or (2) STK392-120 I recomend you replace with the STK392-120 as they are better ics.

IT MAY BE A CONVERGENCE PROBLEM, see some photos and let me know if anything like your problem.

If convergence you will see it better by going into the menu and selecting first convergence, then advanced---this will bring up a grid of lines--should be yellow with no red or blue out of place.

Good news: if this problem it can be a do it yourself repair--I have start to finish, step by step instructions for this repair in this set.

The picture is out of focus and showing double images in different colors.


If picture looks 3d and will not adjust in the customer menu (convergence) the STK-393-110 this set uses is bad.

This is quite common and the part on EBAY sells for about 15 dollars.

The good news is this can be a do it yourself repair. I have available start to finish, step by step instructions for this repair in this set---takes about 1 hour.

After the set is on for awhile, the picture screen bows really bad and makes you unable to see it. It is a WS-55819 manufactured in November 2001


If picture gets 3d etc, it is convergence problem.

See attached typical photos.

The model indicated uses two of the STK-392-570 chips for this and total parts cost will be under 25 dollars to fix set.

I also have start to finish, step by step instructions for this repair in this model.

The colors are all there but there is a double image. Like a blue or yellow outline around everything and words are doubled. I think it is a convergence problem but I don't know how to fix. Please help.


It is convergence problem---set uses either 2 or 3 chips for this (most use two of the STK-392-110 OR 150 CHIPS.

Total parts cost on EBAY would be under 25 dollars.

This can be a do it yourself job if you can solder and have some skill.

Picture doubling like convergence problem?


If you go into the customer menu with the Mitsubishi remote and red or blue are skewed and will not move in some direction---it is a convergence problem.

The model indicated uses 2 of the STK-392-570 convergence chips.

A pair of the chips are available on EBAY FOR ABOUT 14 dollars.

The middle circuit board in the set has to be removed for replacement but I have start to finish, step by step instructions for this repair in this model.

They are based on my own experience at doing this repair in these sets hundreds of times.

They tell you everything you will need and exactly how to do the repair from start to finish.

Hi


Thanks for using FixYa.This is often caused by failed convergence ICs. I don’t think the issue is with the power supply of the unit as the sound is coming fine from the unit. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs (STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. There are
repair kitsavailable which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please do rate the solution if the issue is resolved or post a comment for further assistance.

PT-53wx53g Convergence issue?


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
701cb04.jpg
77ea520.jpg
f0900cb.jpg
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

2c07611.pngSolution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
