7 flashes on my 34HS420 Sony TV

My 3 year old 34HS420 HD Sony TV is doing this now. It shuts off after 5 seconds. The LED indicator flashes 7 times. I don't know what I am going to do with this broken TV. I plan to disconnect it for a few hours and lets see what happens.

7 blinks indicates problem of Horizontal deflection failure. Possible cause can be Horizontal Out Transistor and / or Fly-back Transformer shortage.
If you have TV repair experience and electronics knowledge background, let me know to guide you more OR take TV to local TV repair shop for proper fix.

SONY TV. STANBY TIMER FLASHING


Hi Frank,

Please let me know if it has a pattern of blinks (separated by a pause) or it will flash an exact number of times. Your unit (KV-34HS420) has a built in self diagnostic software that will indicate the probable caused of the fault by flashing of the LED at the front panel.

I have a Sony Wega KV-34HS420 TV that takes several tries to turn on. When I push the power button or remote power on I hear the normal click and the sound comes on for 3-5 seconds but then I hear a second...


Since the set appears to "recover", it suggests either a poor solder connection or bad cap somewhere in the power supply. The 7 blinks indicate the problem circuit is in the horizontal area. Check the regulator (STRxxxx) IC in the power supply. If you do not have experience working with TVs, please refer this repair to a shop. The regulator IC costs around $25.

Sony KV-34HS420 shuts of and stand-by light blinks


  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.

normally this is because of a failed capacitor or two that is located on the power supply board. replacing the power board in this unit will fix this issue.

Will not turn on


When it shuts off. Try doing what's called a self-diagnostic test.
As soon as the television shuts try these steps.

Pressing on the front panel's ?INPUT? and ?MENU? buttons at the same time, and holding for 5 seconds,
activates the Self Diagnostic Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.

Please do Note: The front panel buttons must be used, NOT those on the Remote Control.

? The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
? The flashing then pauses for approximately 1/2 second.
? The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
? The Error Code is repeated a total of 5 times.
Example: If the Error Code is ?24?, the LED will flash two times, pause, and then flash four
times.

The Error Code designations indicating a malfunction, or no malfunction, are listed below:
Self Diagnosic Code Description
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source).
