Question about RCA R61WH76 61" HDTV

1 Answer

I Have a R61WH76 61 in. Projection tv manufactured in 2006. I need convergence chips but I contacted the manufacturer and they do not make them any more. The company only deals with plasm and LED tv problems when you call tech support. Any idea where I can get parts.

Tv convergencen is off convergance is off the red green blue colors ineed to ente on service ineed a code and more information


Your TV most likely has one or more 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.

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.

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.

Stk394-160 Convergence IC, number on top right of chip


I have read both of the above posts.
On the first post, the 'codes' are the date codes. Both parts were manufactured in 2007, and will have no bearing on performance, should both lots not be the same as they were manufactured on different weeks.

On the second post:
There is allot of misinformation on the web pertaining to the applications of STK394-160(E)'s.
This special device was manufactured by Sanyo exclusively for Hitachi PTV's. They will not work in any other projection TV's except for Hitachi. Let me say this again, "They will not work in any other projection TV's except for Hitachi." The 'E' suffix is the nomenclature for PB Free or lead free. All STK394-160's were manufactured as 'lead free'. The 'E' will not appear on the part. Here's more information:

For Hitachi PTV's ( Projection TV's ), STK392-150 replaces STK392-110. STK392-120 should be replaced with STK392-120 or STK394-160's in matched pairs. The -120's are 4 amp devices while both the -110's and -150's are 3 amp. We market replacement kits for -110's that contain two original Sanyo STK392-150's and the associated resistors along with solder and resistor designations for all models. We also have an STK394-160 Kit, along with solder and resistor designations for all models.

Prelco electronics is a direct purchaser of STK's IC's directly from Sanyo Semiconductor Distribution. If you would like the real parts, your search has ended. Parts can be ordered on line, or toll free: 888-773-5268, ( 908-429-9999 local ) Sales X 2, http://www.prelcoparts.com

You have a convergence problem. Go to the convergence menu or consult the owners manual on the convergence procedure and try to correct i if you can.. However if the red image is bowed and or not linear you will probably need to call a technician to repair your set. Most likely the red convergence output chip has failed. This is a common problem with all CRT ( picture tube) rear projectors. Good Luck. Happy Easter

Green Convergence


Hello, I have the same problem and was told that I needed a new convergance chip. They told me who deals in the problems where I live, (TV Repairman) It will cost me 300 for a six year chip and 350 for a life time chip! I was told by the repairman that these chip only last up to 6 years if they are not lifetime. I see alot of this same problem going on right now. These tv were manufactured in 2001, but no one was ever told that these chip would need to be replaced in so few years after spending all that money on the TV. Pasonic would not tell me the price of the chip nor how to get one,were very unwilling to help with the problem other than telling me who do go to locally, so you would have to go thru a tv service where you are.
