Nine blinks of the standby light on any Sony TV indicates a problem on the "G" board. It is located on the left side of the unit looking from the rear. I seems that Sony sent out some sets with faulty diodes in them which fail at some point. They have corrected this and changed the part numbers on newer units. I listed that information below. You must have one of the older units. Do not resolder the diodes as the problem will return in short order.
Here is the error code explanation along with the repair procedure:
" Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will only fix the problem temporarily. This could also be a Panel Module Error or Thermal Error but most likely the diodes. If it is an intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 vdc(negative)."
The G board part number is A-1054-157-A. This board is no longer available from Sony. Rebuilt boards are available at
http://www.moduslink/pts.com . The phone number is 1-800-844-7871 or you can go to their easy to use website and order a board. I have used them for years and have never had a bad board in fact their boards are probably better than factory. Certainly their warranty is (6 months).
Here are the diode part numbers and generic part numbers, and they can be purchased at
www.partstore.com or
www.encompass.com .
REF. NO. -SONY PART NO. - DESCP - GENERIC PART #D6116 ----- 8-719-081-97----------DIODE --------MMDL914T1
------------------------------------------------------------No longer available
New part numbers:
D6116------ 8-719-074-43 -------- DIODE -------- BAS316-115
D6301------ 6-500-567-21--------- DIODE ------- 10ERB20-TB5
Remember, do not get cheap and only replace one diode at a time as you will still have the potential for failure. Also as I mentioned previously, resoldering will give you a temporary fix with the problem reappearing in a week or two.
This should solve your problem but I do know of one instance where a CRT (blue) was shorted out and caused this same problem, and the problem was not the G board.
To eliminate that issue remove the CRT boards one at a time (Blue, Green, Red) and turn the unit on with that color board removed. Of course remove power when unhooking the CRT board.
Continue doing this until all the boards are removed. If the set runs after removing any board, that CRT is bad and needs replaced. I have a tip at
http://www.fixya.com/support/r4573850-change_crt_in_projection_tv which explains how to successfully change the CRT and where to get the parts. If the set never starts up the G board is most likely your problem and will need the diodes replaced.
This is all the info you will need to successfully repair your TV set. Good Luck and be very careful as there are lethal voltages inside the set.
Thanks for using FixYa.
