Probably needs new board. And probably the power board but you should consult the service manual to get the blink code. Boards cost under $100 from shopjimmy.com and eBay type sources.

SOURCE: Problem with Sony Wega 50 in kdf-50we655 light blinks 55 times

I fixed my problem by removing the lamp and vacuuming the hell out of the hole where the lamp lives and also getting all of the dust out of the rear ventilation grids with my vacuum. I put the old lamp back in and what do you know the TV has worked perfectly ever since. My lamp was over a year old and did not show any signs of hazing on the lens that you might see on a lamp that has a ton of hours on it. I just thought I would try to put it back in before I spent a couple of hundred bucks on a new lamp.
TA DA problem fixed.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

SOURCE: Sony wide screen projection tv model kp-57wv600.

I found this solution from SONY's website.

The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.


I hope this helps.

Have a samsung TV UN40H5203AFXZA will not turn on. When plugged in the stand-by light blinks seven times and goes off. Changed power,main and Tcon boards. 3 lights come on the Tcon board but go off.


Please un-plug the cable between the main board & the power supply, apply the AC power to it, if the back lights come on & still on, replace the main board; if the back lights did not come on, mostly the problem is defective back light LED strips.

7 blink by it means the internal temperature problem. Can be because the main board is faulty. You have to change the mother board of the tv . Also remember that when you change the mother baord you have to make necessary setting through service settings.

Panasonicflatscree I have a panasonic flat screen tv model tc50c2 Try to turn on red light blinks 7times until it is un plugged


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

RED LIGHT BLINKS SEVEN TIMES


The most likely problem are two failed capacitors on the main board in the center of the TV The failed parts are easy to identify as the top of the cap will no longer be flat but will have bulged up. DO NOT attempt to remove the back of the TV unless you know what you are doing.
soldering on a circuit board will be required to fix this problem.

When that model Sony shuts down the LED starts blinking as you say but it is telling you something because it blinks a certain number of times and then pauses and repeats the number of blinks. Count the number and then I might be able to help you narrow down where the trouble is.

Sony Vega Service Codes


KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.
