Another convergence problem, note colors skewed etc.

A lot of these sets had problems where the pins break loose INSIDE THE CHIP--causes the kind of problem you are having.

Model number indicated is prone to convergence problems; red or blue shadows around writing or letters---

The model indicated uses two of the STK-392-570 convergence chips; they are located on a large metal heat sink with fins at the front of the middle board inside the set.

The board has to be removed to replace them.

A pair of the chips can be purchased on EBAY (where I buy mine) for about 15 dollars-----total parts cost to fix set should be under 25 dollars.

NO TWO SETS WILL LOOK EXACTLY THE SAME BUT YOU SHOULD KNOW IF WHAT THESE PICTURES SHOW IS YOUR PROBLEM.

I am a expert on these sets and have fixed hundreds of them.

2,2 is short protection and 97% chance one or both of the pico fuses that protect the convergence circuit are blown (bad).

Model indicated uses a single STK-393-110 convergence IC. The fuses and chip are on the middle circuit board which needs to be removed to repair the set. Total parts cost will be under 25 dollars---I use a seller on EBAY who has the chip and the fuses.

I have start to finish step by step instructions for this repair in this model as I have done it hundreds of times.

Soldering and some skill are involved in getting the board out and replacing the parts.

WS-55511 uses a single convergence IC chip---a STK-393-110.

IF convergence is off and will not adjust it needs along with any of the 3.9 ohm resistors that protect it to be replaced.

What happens in these and most projection sets is the chip is mounted on a large metal heat sink with fins to keep it cool----a white grease is applied to the back of the chip to quickly transfer heat--after some years the grease dries out from the heat and the chip fails.

Considering you can buy the IC on Ebay for about 14 dollars plus shipping (I can tell you the best seller there to look for) if you or someone you know can do the repair you can save the set and a LOT of money.

Most shops are going to get 300 or more for this repair.

WS-55511 USES a single STK-393-110 convergence IC.

If convergence if off and either blue or red will not adjust in some direction--The chip and any of the 3.9 ohm resistors around it that protect it--will need to be replaced if they are bad.

Most of the time--just the chip needs to be replaced and the set adjusted.

I have step by step, start to finish instructions for this repair in this type of set.

If you can do the repair, total parts cost will be under 25 dollars--you can buy the chip on Ebay and the resistors are easy to check.

I have photos of the resistors and the instructions tell you everything you will need to do the repair.

If you cannot do the repair--most shops are going to get 300 or more for it---if you go that way make sure you get someone to do it--it should be able to be done right in your home--takes about 1 hour--I know as I have done HUNDREDS of these sets with this problem.
