Red convergence way off

Tries tv unplug,replug it back like about an hour later,by for the tv resetting itself back for factory setting.Now tv should be working,if still have the same problems.The tv have power supply board problems and causes.That the board,where the power a/c cord plug into it.Tries website like Ebay.com to buy a refurbish power supply board for the replacement.

normally when something like this happens, we could right away propose what can be done, in your case, since youve already changed a lot of parts on that tv, you can at anytime fix it. the tv alone is not fixed yet as of the moment but to some it up, experts have already given you some ideas on how to fix the tv. cheers. hope youll fix that tv in no time.

the convergence circuit governing the red picture has gone defective and needs attention possibly a convergence amplifier IC or and convergence coil at the red CRT went defective

hi, if you know little fixing tip's? here's my tip's sound's like converging ic's,gone bad. on the left board there's two a touched to a big heat sink.but before you start'.there's three wire connected to the board written. red .blue.and green.check for burn film resistor's on line red. replaced it with the same.good luck.

rear projection tv can be crt or dlp, if crt, try to adjust red color using the customer convergence feature, you will find it in the customer menu usually under advance feature or video settings, some tvs will just give the convergence caption right on the menu listing. If this does not help then the tv might be in need of some convergence circuit repair, probably one of the power outs is damages and needs to be replaced. If it is a dlp if the red shade extends all over the screen or located in a certain area of the screen then i would have the tech check for light engine trouble, this is a common problem on some dlp systems.if i answered your question satisfactorily please leave your positive feed back. thanks

Your convergence is bad. You need to have convergence amplifiers changed.

Your TV most likely has one of two 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.

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 #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.

Solution #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.

If its only one color its the Convergence amp board that needs replacement. If its more than one color you cant control you need the Convergence power supply board. If you need parts for your model let me know and I will post a link.
