SOURCE: TV Sony KV-29F1E turn-on failure, red standby LED flashes (starts after 10-20 attempts)

When the set ends up flashing the LED, it should be a repeatable count. Can you please report that count here? Also, since the set eventually works, I'd suspect a bad connection or a part that has changed value over time. The blink code will help to narrow down the offending circuit.

SOURCE: Sony TV works briefly then turns off by itself makes a click

It's serviceable, and will need service on either the thermistor that is turning the set off, and/or the parts of the circuit that are overheating the thermistor.

Sony 46" lcd turns off by itself and will not power up again.


Sony TVs come with a one year warranty on parts and labor. Call Sony at 1-800-222-SONY They will find a local company to service this product.

These TVs have a self-diagnostic screen that a tech can access to help solve the problem. Your problem could be any number of things including the fan(s) stopping, the ballast board failing, Q-box issue or none of the above.

Sony 46" lcd turns off by itself and will not power up again.


if your tv unit is still under warranty, first you better bring it back again to the store you just bought it for warranty purposes, your tv has an internal problem, maybe manufacturer defect. Usually the cause of that is a shorted electronics component, say for ex, a mosfet transistor that is located at the power section, or maybe a capacitor that is leaky, and also an open resistor. if you don't know how to troubleshoot this problem, you better have your tv unit repaired by a professional tv technician.

Good luck

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!
