There is a problem with one or two of the diodes on the G board.
Zero Crossing Detector 9 times 9:0 or 9:1
Probable cause • D6116 or D6301 is open (G Board)
symptom • No picture
I hope this helps and good luck!

Here is the info from the SONY self diagnostic.

Five blinks - AKB circuit (automatic kine bias), 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. In addition, unit could be in IK blanking, try turning up screen slightly.

Repair experience required, you might want to take the set to a repairer. as its not a matter of pressing buttons to solve the issue.

Hello: ( 9 blinks on this model indicates an audio problem. Three times indicates you may need service to replace IC501, and IC5002 on the G-Board. It may be better and cheaper for you to just have the G-Board replaced as to replacing individual componets. This is an over-voltage detection issue, and will need to be serviced by an service technician.

Count the number of blinks and google "Sony Blinking codes". You should be able to find that the TV wants you to know. Might be just a dead lamp.

hello. High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

This is a very common failure on Projection sets. Its called a convergence problem.

You may have one or more of the following symptoms.

• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• No Audio / No Video - Makes Chirping Sounds

Sounds like one of these Codes for television repair.

Check out the link above, it may be a bulb needed for your DLP television.

Could be caused by q605, d690 or ic001.

That is a diode in the sub power supply, it is a small board with only a few parts on it to the left of the d board, for the zero crossing detector. D6301 sony part number 6-500-567-21

This is an akb problem, this means that one of three probible solutions,
1. one of your picture tubes have gone bad,
2. A driver ic on the neck module has gone bad.
3. you have a bad focus block.
no's 2 and 3 will cost around $200 to fix, No 1 will be very expensive about $500 to fix.

Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.good luck

The flashes are fault codes. It means your system is faulty. If it is intermittent then it is more than likely a dust issue. Buy an air duster, spray out the back and restart. Should be fine

If it continues to play up then it will be a repair job

Bought a new TV!

The blinking is an indication that a problem was found internally. The blinks should be in a repeated pattern. Please count the blinks and post the number here. That is the code indicating the defective circuit. Armed with that info, we can give you an idea of the problem and the cost to fix it.

Thanks,

Type in Sony Blinking codes on Google you will find all blinking codes and what they mean.

If you're any good inside a TV option(1)is you need to replace D6116 and D6301 on G. board. They are located off pins 7&9 Of T6301. D6116 is a surface mount and in the past I've used a 1N4007 for both... Option (2) replace the G board new, but that's a little extreme. And the orignal Sony p/n# for that board #A-1054-157-A which is no longer available... So it would probably be $300+ dollars IF you could find it... Option (3) remove the G board and send it in to PTS Electronics for a rebuild. It will probably cost about $200 including shipping. And Option (4) find a reputable shop locally to do the repairs for you... I sincerely hope you'll find some of this helpful. If I can help in any way just let me know...

I believe you have a "G" Board failure. If I am thinking correctly, when you open the lower cabinet back, you will see a smaller Board that the AC Cord plugs onto. Their is not a lot of components on it but it will cause this same symptom. This Board according to Sony at last inquiring is not available but they will refurbish it if you send it to them. The best way to do it is to work with a Sony Service Facility, have them come out and confirm it is bad, then they could send it in and reinstall it when it gets returned. ETA on something like this is 3-4 weeks.
I hope this helps,
