Question about Sony KV-32S35 32" TV

1 Answer

Hi, I have a Sony TV which is showing the 5 blink code, the picture is also predominantly pink. I have improved slightly using the G2 control, however the LED still blinks. Tested components on CRT base which appear to be ok. The red input on the CRT base is higher than the green or blue. I have a feeling the CRT has failed, would this cause an error code? The picture was fine for a long time before gradually failing in this way, would the IKB circuit have compensated for the CRT failure until it could no longer do so? Is there any way of getting a bit more life out of the CRT if it has failed?

I can confirm that 5 blinks of the led means "unable to set grey scale" and I expect the software can no longer cope with the error.
You could try boosting the tube with a tube booster but it may kill the tube completely. In the old days we used to fit a 15% overwind for the heaters but that only gave us a few months on our rentals.
A new tube will fix it.
Try looking for a regunning facillity on Google. That will save you a small fortune!

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.

Sony KP-53HS30 Projection TV has pink and blue hue w/timer blink

Depending on your TV, you may have a Color Temperature (Color Temp) and/or Hue setting in the menu. Use these options to adjust the picture to the setting that best suits your viewing preference.
If your TV has a Color Temp setting, you will normally have the following options to select from:
  • Cool: Gives the picture a cooler, slightly bluish appearance.
  • Neutral: Gives the picture a neutral, more natural look and appearance.
  • Warm: Gives the picture a warmer, slightly reddish appearance.
If your TV has a Hue setting, follow the appropriate step below to make adjustments:
  1. Move the setting to the right to reduce the reddish appearance.
  2. Move the setting to the left to reduce the greenish appearance.

Sony KV-27FS210 won't turn on: 5 blinks

If you have little experience of TV repair then take off back cover of Sony Kv-27FS210 and find Screen Control Knob on flyback transformer, turn that knob slightly CW or CCW and turn on TV to get picture. I think you need to turn ON TV few times to get proper adjustement of screen volts.

Above said procedure is for non-tech person.
(Tech person will adjust screen volts (G2) as per procedure mentioned in service manual with proper tools.)

Sony TV KV-36FS76U error code 5 blinks

Cristoffr, this is very, very interesting! I replaced all three ICs per the repair discussed over in Agoraquest:

(scroll about half way down).

This did nothing. However, I had heard that a fan on the back of the TV might keep it from turning off. After the repair failed, I used a fan and for 24 hours the TV has remained on!

The Sony manual for repairing the DX-1A chassis gives testing and possible solutions for each of the blinking codes. About the five blink code it has this to say:

"Blanking - Standby light blinks five timesCircuit - The Ik signals are measured by Y/C, CRT Drive IC201 and areu sed to adjust the RGB gain to maintain color balance. As the picture tube ages, the Ik signals may fall below the threshold for automatic balance and mute/blank the picture. Testing - Increase the G2 control on the CRT’s C board. If that does not return cathode current to within operating range so the picture will appear, examine each filament to see if it is lit.

Then use your scope to examine the signal to the cathode. Go to CN9001/pins 1, 3 and 5 to see if there is a signal coming into the C board. Next check the signal at the CRT cathodes. If they are present, check the IK signal from CN9001/pin 8 of the C board. You should see three pulses and be able to change the level of the signal with the G2 control. If you get about 1Vp-p pulses at pin 8, this is the normal output from the CRT/C board so the problem is on the A board about IC201."

Note, Cristoffr that it mentions the C board in particular, the G2 control. However, it also mentions IC201 on the A board. I am going to post this finding to the Agoraquest board and see if anyone there has any ideas.

At least we have narrowed it down. We with the 5 blink shut-off are rare. Usually with the 5 blink problem the screen *blanks*, yet the TV remains on. I wish we could find a knowledgable tech who could diagnose this. Certainly this much information would lead him/her to a solution. I have heard it might be the flyback transformer, which does have a lead that goes to the C board. Possibly the flyback is not within output limits and the C board is initiating the shut down. Doesn't make sense though, because the power supplies are on the D board. Whew. Who knows? Anyway... I'll keep you posted with any info I gain, and I'd appreciate the same from you.

But perhaps we should do most of our communication here for the benefit of anyone who has the same problem. Just a thought.

5 blinks, Sony KP-65WS500 stays up only with one CRT gun at a time....

5 times blinks shows White Balance error in tv. You need to adjust Screen Volts (G2) and problem will resolve. Screen volts controls located at Focus Block as shown in below picture.

SONY KV-XF21N90 WON'T TURN ON, Blinks 5 times

5 times flashing light shows following possible problems in your tv..

• G2 is improperly adjusted.

• CRT problem.

• Video OUT IC1800 is faulty.(C5 board)

• IC301 is faulty. (A board)

Most probably cause is G2 voltage adjustment. If you know how to do it, please go ahead or look a tv tech around.

Sony Television

Unfortunately that's an indication of the crt going bad in a Sony.
You can turn the G2 voltage down on the flyback or have a tech rejuvenate the picture tube but either of these are only a temporary fix..
The flyback is the rather large transformer with a red (anode) wire coming from it and attaching to the crt. (looks like a suction cup).
There are two adjustments on the back of the FBT, one is screen (or G2) the other is focus. With the unit on turn the G2 counter clockwise just a little and the picture will get slightly less bright. That should stop the picture from blinking out - or doing so as often. But again, it's only temporary!
Good thing Santa's almost here... :)
