5 Answers

Shuts off intermittently

The standby blinks 5 times. The diagnostic screen shows AKB circuit.
Also could be IK blanking. One solution is to" turn up the screen".
How do I do that? Do I need a Pro to fix this?

You can try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

This is issue with the tv : * 5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.Needs pro to fix this...


Good luck,,,,

Auto Kine Bias; a circuit that holds the video OFF until the picture tube (kinescope) is warm enough to run video. So, if there is trouble within the AKB it may not be turning on the crt. Or, the crt could be cold, or there could be power supply problems (which I favor because if the audio is gone too, that means it is not a "video only" matter).

    Hi again,

    Look at below picture and find the Screen Control to adjust volts to fix IK problem.




    Adjust RV9002 on the C Board so that the voltage on red, green and

    blue cathodes is 170 V DC.

    Regards,

    Regarding your question, how do I do that, it depends on your skills and knowledge.

    If you think, you can understand above information and can do the job, thats ok...or call tv tech guy to fix it.

Sony kv-32fs120,no power:3 and 5 blinks


http://www.riddledtv.com/forums/sony-kv-32fs120-dead-blinks-5-times-t329.html

Thank this guy and you need to see a qualified repairman

Chassis BA6 for anyone elses information:

I would check the Bridge rectifier first to see what voltage you are getting. I have a note here to check D611 which is the bridge rectifier.



Here are the Sony blink codes:


Unit is dead and there are no blinks---Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open)

Continuous Blink Once A Second, No Pausing As Discussed Above---
No reply from the jungle IC301 (data bus is busy, shorted to ground or held high), IK video path is defective.

ONE Blink--- not used for the self-diagnosis

TWO Blinks---B+ 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.

THREE Blinks---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.

FOUR Blinks---No Vert. Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.

SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.

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.

EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402.

Intermittent problems ?? This is a great feature. You can also bring up these fault codes ON-SCREEN to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, Press the following buttons:

Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC. We have repeated them in parentheses in the text for the "Blinks" described above so you can correlate between the diagnostic screen and the blink codes.

So, now that you know about these self-diagnostics, how do you use them? Say that you have a set with a black screen. You see that the LED is blinking 4 times....This would tell you that you have no vertical and that is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault.
