These blinks are fault indications. For Philips brand TVs, you cant read out the number of these blinks directly as they occurs. There is a special procedure. If you wish to get more details, check this site. Pull up older posts there. Check the site with patience, as it has over 2200 posts now. All are related to electronic equipment repair help. Blinking codes reading procedure and all other details are given.

Here are the blink codes. 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 Cboard, 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 newer models of Sony TV sets, this code means that T8005 is 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. 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, volume 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 problems named, are 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. 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 four times. This would tell you that you have no vertical sweep, which is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault. It's not a sure cure..

If you are not a professional Electronics guy,it is beyond you to tackle this problem. otherwise log on to www.free service manuals.com and see the SONY Blink codes and also download the service manual.best of luck
SOURCE: Timer/Standby light blinks but no picture or sound when power button is pressed.
I'm having the same problem. My stand-by light blinks 3 times though. The tv clicks as if it is going to turn on, but it never does. Is there a simple solution to this problem?

If the TV goes in standby, then it is in protection mode.
Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.
1Theinternal circuits are jammed because of electrostaticcharges accumulating on capacitors, or because of a wrong voltage readby the main chip on your monitor controller board. this started theprotection circuit.
2 The protection circuit detected a wrongvoltage or abroken contact, identified an internal fault and kicked in, starting the flashing light.
If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Payparticular attention at inverter and power board, power board can beinspected looking for bulged or leaking capacitors, then tested with amultimeter. The inverter is more difficult to test , there is need toread voltages, should be done by a tech. Also the LCD controller board can cause same problem
On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.
On Rear Projection : check lamp, lamp ballast, power board, and convergence.
On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.
Hi,
The
Standby/Power light of the TV blinks when there is any internal malfunction in
the TV. The self-diagnostic function of the TV will cause the STANDBY light to
blink or flash when the television detects an issue. The number of times the
STANDBY light flashes corresponds to a specific issue.
Few
examples are given below; some of the issues may be resolved without the need
for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a
power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your
set. The set will need to be serviced to allow a technician to determine the
specific issue that needs to be repaired. If the power light flashes three
times in sequence in a Lamp TV, the lamp cover is not securely attached.
Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power
problem.
6 blinks: - This indicates that there is some kind of audio problem with your
set.
7 blinks: - This indicates that there is a temperature problem with your set.
Please check to make sure that the air vents on the sides and back of the set
are not blocked or clogged and there is adequate ventilation around the
television. We recommend that you check and clean the vents periodically to
make sure the set receives adequate air flow. If the problem continues, the set
will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your
set. If the flash sequence is not listed above or the light continues to flash,
follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If
the television is plugged into a power strip or surge protector, remove it from
the power strip or surge protector and plug it directly into the wall outlet.
If the issue is resolved, the problem is with the power strip or surge
protector and not the television.
If
the issue continues to occur, service may be required.

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 A2 slightly.
