Hi, well whenever I turn on my tv the red standby/tv button flashes more than 10 times and continues to flash. However, the picture never shows up. I don't know what happened, and I don't know what to do. Anybody know anything?. It turns on..stays with the dark screen and you can't even hear anything.

My sony TV, when I press the power button it sounds like it is going to turn on then the standby button blinks 10 times then stops for 30 secs and then blinks another 10 times. What is wrong?


Flashing of the standby LED light 10 times (KP-46WT520) is a "High Voltage Protection".
Affected parts are as follows :
• Q8014 or Q8013 have shorted replace along with R8051 on D Board.
• IC8005 is damaged (D Board).

You must know how to test transistors, resistors using the multimeter if you are going to DIY.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to seek for an assistance of a qualified TV Technician to isolate the above faulty parts.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Tv wont power up Standby light keeps flashing.

First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.

Tv went off while watching a program power standby red light blinks 6 times then pauses then repeats tried unplugging unit waiting a few minutes then replugged same results nothing. can anyone help me ?...

Here's an excerpt from the Sony Manual online. And the link -

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.

Sony KDP-65WS550 flashes when you try to turn it on

No the DLP units can flash more than 8 times. 9 blinks mean Zero Crossing detector which means diode number D6166 or D6114 is open they are on the A board.Let me know if you need any further info.

I own a Sony T.V. model #KV36HS510, Serial # 9024184,Event# E36002407 and it"s aTrinitron brand name. Like the problems before no picture or sound, stand by light on front of unit flashes. When trying to turn it back on you can hear the power click, like it wants to turn on, but does not.

Troubleshoot-5 blinks red light front of TV

TURN TIMER OFF. GO TO SONY.COM, TROUBLESHOOTING, OR The STANDBY light is flashing on the television and there is no picture or sound. Solution
sp.gif sp.gif 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.
