Question about Zenith R57W46 57" Rear Projection Television

Convergence IC replacement

Hi there - a local repair company has told us the IC's required replacement in our TV. They then told us that the parts were back ordered with no ETA; I have since found numerous companies online with replacement parts with the same part # but they are all a different manufacturer. My question is this; are parts with the same # truly the same? does the manufacturing brand matter if the part numbers are identical? thank you!

No as long as the STK number is the same they will work. Just be careful where you get the parts as alot of places online sell cheap chinnesse made ICs and they wont last. I usually get mine at the following link, and I havent had any trouble with their ICs.

Panasonic projection Model #PT-53TW53 displays double images and projects shadows on all text. Scrolling banner on bottom of TV scrolls slightly upwards and back down with shadows over text.


This is failure of convergence out ICs in TV that will be replaced, requires soldering work to replace two big ICs STK392-110 (convergence out) on main board. If you are not comfortable with replacing ICs, ask help from local TV repair shop.
Required ICs are available in Part Store.
Thanks.

Toshiba big screen The tv is like double exposed . I have a toshiba big screen tv and I have double images in red and green. How do I fix this problem?


This is likely your convergence ICs(chips). If you can bump it then the ICs (chips) are still ok, it just needs resoldering.
my company charges $300-400 for the full repair (replacing ICs, full realignment plus cleaning)
if you can find a company that will resolder for you, it could cost $100-200 maybe. if you are a handy person with soldering skills, you could repair yourself. i can instruct if needed, but convergence IC soldering requires decent soldering skills. you will find the ICs on the largest heatsink in the tv. the part number starts with STK. if you replace them, check the resistors in front of them and replace accordingly. most toshiba will blow up to 3 fuses (f850, f851, f852)

Your TV most likely a convergence 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.
Here are some photos of convergence problems.

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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.
