Attn sd tech-convergence problem with my 53" Hitachi rear projection 10 years old-wwould like to repair it myself

The convergence repair if done is possible do it your self; If you have also a bad blue picture tube or some issue related to the tubes then the set is beyond any reasonable repair.,

not always easy to replace a set that cost in its day a lot of money but it is now about 9 years old and that is about average to this type of set.

It means one of the two pico fuses for CONVERGENCE is blown.

I will attach photo of the fuses; they and the two convergence chips this set uses are on the middle circuit board--also a photo of a typical IC.

Parts cost on EBAY will be under 20 dollars.

Instructions tell you everything you will need and exactly how to do the repair.

Give me a email and I will send them free.

If this was helpful rate this solution as very helpful as I do this here for free.

Chips will look like this but have the STK-392-570 ON THEM.

Sounds like a convergence failure, here is a tutorial I made:

Let me know if I can be of further assistance.

GO to customer menu and with the remote select convergence--if skewed and will not move in some direction, convergence problem.

Total parts cost on EBAY FOR PARTS would be under 25 dollars.

This can be a do it yourself repair.

I am the right person to talk to.

If convergence problem total parts cost on EBAY would be under 25 dollars AND I HAVE START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THE DO IT YOURSELF PERSON TO DO THIS REPAIR.

THE instructions tell everything you will need and the best way to get at the two STK-392-110 CHIPS THAT NEED TO BE REPLACED.

Repair involves getting at and replacing both chips, it does involve being able to solder--not hard on this set.

If you want the instructions here or provide a email I will if you rate this solution very helpful give them to you for free, they are based on my actual experience doing hundreds of these sets with this problem.

See attached photos of what the chips look like and what a typical convergence problem looks like.

SD TECH





The black parts are the chips, this is Hitachi but EXACT SAME TWO CHIPS ARE USED.





Typical convergence problem; no two will look exactly the same.

If it looks like the attached photos it is a convergence problem and typical.

I can tell you what is needed to repair this if you are a do it yourself person.

Let me know if the photos look ANYTHING like your problem.

STEVE--SD TECH

You can fix it yourself but it involves two things--being able to get at the convergence chips and being able to solder etc....

Not a difficult repair and total parts cost should be under 30 dollars.

Let me know if you need help as I am here to help.

I will give help and options if you ask.

Yes,U know how to solders?Must replaced the 2 convergence ICS and all it resistors. Buy a convergence kit at Tv Repair World.com,Tvrepairkits.com.To repair it ur self. The shop will cost U $300 for parts and labors.

hi, which amplifiers??? audio or convergence ? repairing yourself means you are proficient at solder re-work and posess that equipment, I own a 9 year old Hitachi projo and wouldn`t trade it for any of the new formats, I can advise you where to get the ic`s once you tell me which circuit has actually failed, video-tek

the problem is convergance the amplifiers (two of them) have failed. posibly some resistors or pico fuses are bad along with them. they need to be replaced then realiegn the convegance. the cost of repair may be $200.00 to $350.00 depending on the tech you get.
