The 4 blink code usually indicates a loss of vertical deflection. Check the solder connections on the vertical IC. If the connections are OK, replace the chip as it is defective. This chip will be a small flat IC with about 1 pins or so attached to a heatsink. It will be marked LA3847 or something similar.

Keep us posted.

Hi
In sony tv`s the 4 blink code(sony error codes)usually means that there is a vertical deflection problem.
It is often caused by a faulty vertical output i.c and/or related components. If you feel handy with a soldering iron let me know and i`ll help you with it.
Hope this help Merry Christmas

Doesn't power up. Red standby light flashes.


How many times does it flash?

Odds are the A board components. Let me know how many times the stand-by light flashes, and I'll tell you want the fault might be.

The red light on my tv blinks 4 times and will not turn on?


This is most likely due to the all-to-common power supply failure. You can test power with voltmeter

Power clicks on and red power light flashes but no picture


The problem might come from the fuse inside was blow out. if you have a multimeter then open the rear cover. The fuse lays near the power cord. Take it out and use Ohm meter to check it connectivity. If it is no connectivity meaning the fuse was blow out. Replace a new one with the same value (Ampere and Voltage). If it does have connectivity, the problem needs technician to find out as it relates to many parts on the circuit board.

Sony FD Trinitron WEGA KV-24FS100 24" TV On/Off problems


I have spent about 4 hours tonight researching several tech sites and the Sony service manual for the same problem with my Sony KV-32HS510 unit. I was able to download the manual from a website http://www.eserviceinfo.com/downloadsm/31649/Sony_KV-32HS510.html and a TV Repair training lecture paper at http://www.repairfaq.org/sam/tvfaq.htm#tvhvp .

These TV sets have a safety feature where it will shut back down if a high voltage is indicated. Unfortunately, the electronics for these safety features are not very reliable and give false indication. Letting the unit sit off lets the capacitors leak voltage as well as cool off. These two factor help with the unit not falsely indicating a high voltage condition.

The D Board seems to be the most common failure component, but a 6 times flash could be an overcurrent/voltage failure from the A, B, or M boards. A 7 times flash is a Horizontal Deflection Stopped error with no additional information given in the manual for a fix. Again, in most blogs, the D Board seemed to the source of the failures.

A refurbished D Board part no. A1300319A can be bought for around $200 with a new board at $550 per the www.partstore.com site. Then add $100-$200 for an actual TV service technician and you have a repair bill approaching the costs for a new flatscreen TV.

Some tech types posted that they have actually repaired their boards by replacing individual components for around $40. You may find a service shop that can do the same component level repair at the $100-$150 level cost. It turns out that the closest authorized Sony repair shop is 2-1/2 hours away from us. Good luck finding someone close by.

We were able to get our TV to come back on after dozens of attempts and plan to leave it on until it dies all together. I may attempt my own D Board replacement when the time comes.

Good luck!

TV won't turn on


The set is in protective shutdown because a problem was detected. The 5 blink code indicates that the problem circuit. In this case it is the blanking circuit. Were there any indications of problems prior to the storm? If not, I'll need to lok up this one for the specifics. Do you intend to repair this yourself?

Let me know and I'll provide the details.
Thanks,
Dan

This may be a power supply, and or a high voltage, or a scan ampplifier failure. The set would have to be properly trouble shooted by an experienced TV tech to determine the exact failure. This is not something you can fix yourself at home.

Well, I have found out that the number of red light blinks is a "blink code" that indicates the nature of the fault with the TV. Usually these are various failures of internal fuses or circuit boards. There's a fair amount of information on threads at techlore.com on this, so try searching there. Teh specific codes and manuals are usually it seems under license from Sony and not available for free to the public. Sorry!
