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.

You will need the service manual to locate the blown resistors and or the circuit protectors in this TV set. If you know how to read the service manual, the schematic, and trace the circuit, know how to use and ohm meter and a volt meter, I am sure we can fix this set together. Let me know with an e-mail address so I can save you 30 bucks for the service manual. Good Luck

Hello, the good thing is that the led flashing is a blinking fault signal, the blinking means there's a faulty circuit. here's what you may want to do if your semi electronically inclined find a online service manual site, and at times it is possible to try a free manual search for your specific model,. the amount of times the light blinks will determine the faulty board. exchanging that board or repairing the faulty components it the tricky part. working at high heat levels and for extended periods of time may overheat and damage internal circuits and this is typical with these flat screens. but different manufacturers have different blink codes so it's a model specific manual you will need for this repair, and as in the other previous answers you may want to consider shipping/part cost/ before you go about servicing it. If you can handle this type of repair check auction sites for the boards it is way cheaper than service center pricess for boards, hope this helps.. have a great day.

What do i do if my tv says code 21


somethings wrong with the high voltage circuits and its not allowing the tv to work -to protect you from xrays!

I would send it to a professional repair man or splash out and buy an LED or plasma screen. Don't fiddle with it yourself as the voltages concerned are very dangerous

Red distorted color near top of screen not having much luck with trying to converge the lines on the tv set form. already tried factory reset


Reset will not cure a convergence problem.

this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).

If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.

Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.

No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.

If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

I have a HCL473W with a 'concave' screen effect on 2 colors??


You don't need to replace the whole board, regardless of which board it may be mounted on. The STK IC convergence chips alone are all that need to be replaced. You can order them from a number of different online sites. You can try Alibaba.com. If you have any more questions, feel free to ask!

Convergance circuit board


I located the board at PTS Electronics. Mine was the digital convergence board.
A little pricey but did the trick. Recommend that if you do not know how to drain off the capacitors. Let theTV sit unplugged for 3 to 5 days to drain them down below a possible fatal shock level.
Recommend taking good digital photos for your reinstall if you have no schematics or real electronic experience. Priceless advise !!
Do not touch any settings to try and adjust without knowing the original factory settings. It will get expensive to have a tech readjust. Lots of time to adjust and the tech knows you were there. $$$$
