Question about Sony KP-53HS30 53" Rear Projection HDTV-Ready Television

Open Question

Possible convergence issues...please advise

Turned my kp-HS5310 tv on last week and the color were off as well as the words on top and bottom - like a wavey line motion. It appears to be a convergence problem but I'm not sure.

I've tried several time to push the "flash focus" button in front of the tv as stated in the manual but it doesn't fix the problem.

I heard that you can manually adjust the convergence with the remote. Does anyone know how to do this or offer any other possible solutions to fix on my own before I have to call a technician?

Thanks in advance!

    My TV set just started the same problem. I've tried the Flash-Focus without any success. I'm wondering if I should call a repair guy or just replace the set. Please advise if anyone else knows how to fix.

Your TV has gone crazy on you because your convergence IC's have gone bad.   These IC's operate at a very high temp, and usually only last 4-5 years.  
If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see 2 lage IC's , probably STK392-110, or STK392-120's or something close...regardless - you can go on ebay to order the new ones, but MAKE SURE they are Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may only last 2 months.. 
You will also need some "Heat transfer paste" - you can pick this up at radio shack.   Once you remove the old IC's, test all the large resistors near them.. pull one side of the resistor out of the board so you can check it out of circuit. they will usually have the value in Ohms, printed directly on the resistor, but you may have to use the resistor color code to find out what value they are....However, usually if there is any damage, the resistor will look like it has been HOT or fried. replace the IC's and any bad resistors, and you should be good to go. If you need to order a resistor or two, 
http://servicemanuals.vstore.ca/index.php/cName/convergence-resistors   If after replacing the IC's and any defective resistors, the convergence is still bad, make sure to use a multimeter to check ALL fuses on the boards, --- sometimes when the IC's go, they will take out a fuse to the convergence power supply. If you find any bad fuses, replace them accordingly!   If this STILL doesnt make it look right, you will need to find out how to get into service mode and do a coarse convergence adjustment. This information can be found in the Service manual for your set. If you dont have one you can download it at manualuniverse.com
Hope that helps!

Top and bottom of TV screen collapsing.


You may have a convergence problem (I will attach some typical photos).

When it does it go into menu and call up convergence grid--if lines skewed and colors mixed it is convergence. This model I think uses two of the STK-392-560 chips and both would have to be replaced if it is your problem.

I can provide more info if you find this is what you have.

Sony TV rear proj works but color is blue


Problem : 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 :


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.

I hope this will solve your issue.

Good Luck.

If my solution proves useful please accept it.
