    +Everything was fine when we turned the TV off last night. Went to turn it back on today and the power light just blinks 3 times and quits. We recently stopped our direct TV but we've been able to watch DVDs since then. Can't figure out what the problem is. Any help is appreciated.

Sounds like the two large caps in the psu have gone slightly low in value and may need replacing.

Sony TV set, KV20FS120 BA6 chassis: light blinks, set isn't coming on. Why?


Sony sets like this have a built-in self-diagnostic function.
The blinks of the Standby LED are the self-diagnostic codes.
There may be more than one error. The blinks indicate only the first error.

Unlug the set. Wait 30 seconds.
Prepare to count the number of times the Standby LED blinks.
Plug the set back in. Count the blinks.

2 blinks
  • Diagnostic Item Description: +B overcurrent (OCP)
  • Probable cause:
    • H.OUT (Q506) is shorted. (A Board) (20"/21" models only)
    • RGB Amp (IC1751) is shorted. (CV Board)
  • Detected Symptoms:
    • Power does not come on.
    • Load on power line is shorted.
4 blinks
  • Diagnostic Item Description: I-Prot
  • Probable cause:
    • +13V is not supplied. (A Board)
    • IC545 is faulty. (A Board)
  • Detected Symptoms:
    • Has entered standby state after horizontal raster.
    • Vertical deflection pulse is stopped.
    • Power line is shorted or power supply is stopped
5 Blinks
  • Diagnostic Item Description: IK (AKB)
  • Probable cause:
    • Video OUT (IC545) is faulty. (A Board)
    • IC001 is faulty. (A Board)
    • Screen (G2) is improperly adjusted.
  • Detected Symptoms:
    • No raster is generated.
    • CRT Cathode current detection reference pulse output is small.

The above may be of little help. Your best bet is to download the service manual for the KV20FS120.

SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

Tv sony stop after 20 min standby led flashes 3 times


HI,
By three blink it means the B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is because there is problem in the power supply circuit. Check for any dry soldering in the power supply side. If the tv is working properly for 20 minutes then its sure that there is some dry soldering joints in the power supply side. You have to resolder suspected soldering contacts using soldering ion and solder. The dry soldering joints will look like on in the picture.

Im having a problem with my TV turning off and the standby button flashing 7 times, after it shut off. What can I do.


hi,
Blinking led in sony tv is its self dioganising function. 7 blinks by it means the horizontal output voltage increased above 33k.
You have to check the power supply stage of you tv. Normally in sony tv dry soldering can happend in the power supply stage. It will lead to unregulated voltage output from the power supply. Resolder all the points in the power supply section it will solve your problem.

2 blinks means - over current protection (OCP) , unit goes to the standby
mode then displays the 2 blink fault. Could be a short in the power supply of
any of the circuits.

KV-36XBR400 won't turn on, "standby/stero" light


You are correct. You are right about the power supply and replacing with led hdtv. You will be happy with a Samsung led. Time to upgrade.

TV turns off by itself after being on for 60 seconds


Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.

A qualified tech will need to practice visual acuity technique! Look at power supply circuit for signs of stress,dis-coloration and/or bad connects.Check for bad 47mf/25v cap in area of stress.Replace BC-327-25 xistor w/BC-328 and replace BC-337-25 w/BC-338,if present in your set's chassis style.
