Red Convergence will not line up

On my Hitachi there's a convergence button on the front panel. Press that button which will give you red & blue lines. You have to use your remote to converge (align) those lines to correct the picture. If the lines won't converge I've been told it could be a bad convergence IC & tech is needed to fix...could be approx $300 to fix.

possible fuse on convergence board. possible defective red convergence ic. "red lens" is fine. it is a electronic problem

go into menu and adjust convergence. if red moves, it just needs adjusting from your remote. if it doesnt move or is bent then you have a bad convergence ic. possible fuse. suggest local service center. sorry

if i understand you right your blue convergence is off? and you have tried to go into the adjustment for the convergence? now do you crosshairs move up and down and left and right? on bpth red and blue. I see two possiblitys for this your convegence output ics commonly called stks or and you convergence ouput resistors. not a difficult repair for most shops and aroud 250 for parts and labor the ic run about 45 apeice

stk392-110 i think mine was made in 2002 and i also had to replace mine

Did you remove 1 leg of each resistor out of circuit when you checked the resistors? sounds like thier is still one resistor open or maybe one of the new IC pins need abit more solder.

convergence ic bad

seems like your tv got convergence problem . try setting up the convergence , use remote . if it does not help you may need to change convergence ic * 2

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.

SOLUTION

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.

If the blue colors will not line up, and the blue appears to sag inward from one or more sides, then you can bet that one of your convergence IC's has either cracked loose or burned out. The IC should be resoldered or replaced and the convergence realigned by someone experienced with projection TV convergence circuits.
