Question about Sony BRAVIA KLV-S40A10 40 in. HD-Ready LCD Television

2 Answers

Tv shuts off spontaneously. red power light blinks.

My 40" bravia about 2 years old shut off spontaneously in the middle of a program tonight. Red power light constantly blinks rhythmically 4 times. Tried unplugging and replugging. Gets power with sound, no picture for about 5 seconds then spontaneously shuts off again and the red power light begins to flash. Changed power bars. No effect. Is there a hardware problem? Something burned out inside? Expensive to fix?

Re: tv shuts off spontaneously. red power light blinks.

Re: sony flat panel lcd tv mod. # klv s 40a10.
No power. When power button is pressed, nothing happens.
The stand-by at the power supply ( cn6201) measures to be 3.47 v. instead of 5 v. However, when I unplug cn6201 (5 pin connector) I can read 5v. at the power supply.
Any suggestions?

Re: tv shuts off spontaneously. red power light blinks.

Sounds like you may have a bad inverter board. This board powers the back light on the lcd panel. This board may be replaceable or the complete panel may need to be replaced. If the panel must be replaced you will be buying a new tv. Very expensive part. If the inverter is available seperatelly then it may be worth repairing. You should contact a Sony ASC for an estimate. Good Luck

Sony bravia shuts off

A short circuit with its main board component, can make 8 blinks of standby/power light. These blinks [flashes] are fault indication. You can get an idea about the faulty stage circuit inside the TV, by the number of these blinks. Count it carefully, by switching it ON and OFF, more than 2 times at least, so that, you can make sure about the number of these blinks. If you wish to get more details, check the site linked here. Surf the site in "MOSAIC" view.

My bravia will not stay on.

If Bravia tv wont stay On and shuts Off itself that means it got some internal problem, you will see red light flashing on tv front in specific blinking time that is an error code, let me know how many times that red light is blinking after three seconds long pause to diagnose problem.

My sony bravia tv is flashing red stand by light

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
