Sony KV36XBR800 standby blinks 4 times

Hi,

I've got a 5 year old Sony xbr800 which isn't powering up and the standby LED is blinking 4 times. I know the problem is on the D board, but can someone pin it down a bit more and maybe narrow it down to couple of components so that I can try to fix it myself ?

Thanks

    Thanks for your suggestion Dan!



    Do you know which board I need to look to resolder this IC ? Also is there another part number for this ? I couldn't find LA7837 in the manual, and just in case I need it I'll have to buy it from somewhere.



    Thanks!

The 4 blinks usually mans that there is no vertical deflection signal. Look for a small flat Ic with about 11 pins that may be marked LA7837 or something similar. Resolder the pins on that first. If that fails to resolve it, replace the IC.

Keep me posted.

    When you find the vertical Ic, it may be another part number. I'm doing this from memory and don't know all of the numbers for all sets. Also, the marking is the generic part designation, the Sony manual will only have the Sony part number. Post the actual marking here and I'll confirm that you have the correct part. Purchase it from a generic supplier and you will save over 50%.

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.

KV36XBR800 5 blinks


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 stage 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. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Problem with Sony FD Trinitron WEGA KV-32HS510 32" TV


Blinking of standby LEDs to Sony TVs are fault indications. Form the number of blinks occur at one time, the repairman can get an idea of the faulty stage inside it. According to you, it blinks 4,6 & 7. Just visit this site, It has details about blinking codes to Sony TVs, both CRT based, Flat panels and Plasmas. I can't provide more advice to you, because the number of blinks are not constant. Check the site, and get it.
