Sony TV KV-36FS76U error code 5 blinks

Sony KV-36FS76U error code 5 blinks (AE5A chassis)
Please can you help me with this TV.
I just got this TV from a guy who has been using it for a year keeping it
alive by playing a fan on the back. I found that it would also work if the back
was removed.If not it would switch off after a few minutes with error code - 5
flashes.
With the set running I put the back cover back on and within about 4 minutes
it tripped.
I considered which part could be so dramatically effected so quickly and
concluded that the PCB on the tube (the C board) would be the one so simulated
the effect by putting a dry cloth over this PCB. Within about 1 minute it
tripped. However now there is no video at all. Thare is sound for about 10 secs
then it trips and the error code is still 5 flashes. I find it hard to believe
such a minor action could have damaged it. If I disconnect the C board it does
not stop the set from tripping. Also If I disconnect the 2D board that carries
the LOPT it still trips.

I can be Emailed at chris.lowdon@ntlworld.com

    I am having a similar problem with my sony. I was having a problem when I turned it on, you could hear the relay click then in about 5 seconds it would go into diagnostic mode and blink 5 times. I took the back off and played with it turning it off and on and finally it came on and stayed on. After turning it off for the night, the next morning it would take it about 10 times of turning it off and back on for it to stay on, The 5 blinks is telling me it is in the video output section which I assume is the "C" board. Could the power supply board create this problem? Any help would be appreciated.

I had the same problem, my telly was showing error code 5, led blinking 5 times and then the telly enters into standby mode. There is a great site with pictures of this telly and I found the answer here:

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

http://agoraquest.com/viewtopic.php?topic=1121&forum=34&start=75&select_page_number=6

(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.

Cheers,

Sean

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

Sony FD Triniton WEGA KV36FV27 no sound or picture timer blinks five times pauses then repeats five blinks. Please advise what this code means in lieu of call a serviceman. Thanks--disabled senior.


in this model error 5( 5 blinks then 5 blinks) is indicating AKB, TOO LOW or ABSENT beam current. Meaning the tube has gone bad. You will need to replace the tube. I am sorry for the bad news.
hope that doesnt hurt my rating.

Sony Wega KV-34HS510 standby blinks 7 times in red


Hi and welcome to the site,

Initially, the Sony KV-34HS510 uses the DA-4 Chassis. On this chassis, 7 blinks refers to the fault "Horizontal Deflection Stopped" indicating a problem with the horizontal section. Offhand, check, replace the HOut transistor and have the FBT (flyback transformer) ring tested.

Good luck and thank you for asking.

Sony KV-32HV600 won't turn on.


If the blink repeats the same number of times (up to 6 or 7) between pauses, the number of blinks is a trouble code. Determine that number (count), then search this site and the web for your TV model and that code. Also look on the rear of the set for the chassis number, and search on that keyword.

Blinking STANDBY Light front of Television


Hii...
Refere to Sony Blinking Codes :
5 Blinks ===> cause AKB circuit (AKB). Something is wrong with the video. check components on the C board, also check the A board. Also unit be in IK blanking, try turning up screen slightly.

Hope can solved the problem....

5 BLINKS


My first guess is IC 702 in the crt drive circuit. You could open the back and unplug the "C" board from the back of the crt and then power it on. If the set comes up and you have good audio that will isolate the problem.
If IC 702 is the problem you'll have a couple of other things to check, R533 .47ohm 1/4 watt fusible resistor and C541 22uf 100v both on the "A" board because they tend to stress when IC 702 begins to leak. Replacing IC 702 and not the resistor and cap could cause 702 to fail again.
If IC 702 is not the problem then it could be the flyback.
Hope this helps!
