Sony TV Error Code - Nine Blinks Solution.

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.

when i turn tv on green light blinks two or 3 times then goes back to red and never turns on


We need to know what make and model to accurately answer this question, but if you have a Sony, here is the information -
Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.
The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again. Here is a list of the problems that might have occurred indicated by the number of blinks.
Unit is dead, 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 - 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 vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
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.
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. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.
Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is 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 (negitive).
Ten blinks - 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.

I have a 51" sony HD tv. I turned it on and there is no picture, screen is black. A red light is on on standby mode. the red light blinks. Please help me how I can fix this problem thank you in advance.


According to the service manual for this model, Nine blinks indicates a Audio error. On either the A and or B boards. The plus +19V line is shorted. On the A board IC708 is Faulty, this is the audio output intergrated ciruit chip. Also PS701 and 702 is opened on the A Board. Look at the board markings for these locations and replace these parts first.

Sony Trinitron won't turn on - standby light blinks nine times


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
