No -
Yes -
If you call a qualified Sony Service Dealer they can sell you a new board if you have the board's part #.
If you have a part # please call AVI Systems 952-949-3700 and speak with Rob. He may be able to help you get a replacement board if they are available.

The standby light is blinking 10 times


Hi,
TEN blinks - Check for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, "D" board.

High voltage in TV got problem and that's why TV gives 10 time blink error code.
Qualified TV tech will fix it as its bit complicated fix.

Parts are available but problem of High Voltage Protection (10 times blink) requires high expertise and experience of TV repair.

You must know how to test transistors, resistors using the multimeter if you are going to DIY.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to seek for an assistance of a qualified TV Technician to isolate the above faulty parts.


Parts are available in http://www.partstore.com/CustomContent/PSTOR_ECO/CustomError.htm#PartsearchSKUList

Hope I helped you.

Thanks for using Fixya.

According to the tech manual I looked at, it's a bad board - it just doesn't say which board. Sorry. Looks like it's making a trip to the shop.

Good luck.

KP-61HS10 with 6 blinks


Set screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.
Hope This Helps

you need to replace both convergence ICs they are easy to install. You need two STK392-560 ICs you can get them at the following link and they provide free installation instructions as well as free online messaging with a repair tech while youre donig the repair. It takes about 45 minutes to do the repair and you will save about 400.00 by doing it yourself. Heres the link I am one of thier repair/support techs. This is a very easy repair.
