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.

Sony Trinitron KV-32FS320 5 blinks


Sony KP53HS10 5 blinks
Five blinks means "Video out abnormality detection". Possible problem areas are as follows:

Video out, IC7101, 7201, 7301 and others in C board circuit.
Q510, 516, 524 (A board).

There are actually three C boards, the CR, CG and CB boards. They are attached to the rear of the red, green and blue CRTs, respectively. I wouldnt attempt to repair the set myself. I would solicite the services of an authorized Sony servicenter.

Blinking red light 5 times


This problem is due to moisture content in the flyback transformer surrounding area. Due to this moisture content screen control voltage is changed. Without getting a exact voltage the indicator will not stop. 5 times blinking is only for screen malfunction. Make one general service by cleaning the deflection area and adjusting screen control the problem is solved.
