The red standby light is flashing twice with a pause, then twice and a pause etc. There's no picture or sound and the light flashed whether we have the tv on or off. Any suggestions?


This blinking is a diagnostic code. Please update this with the model number. These sets contain circuitry that will shut the set down and display a code like this when a problem is detected. With the model number, I can look up the problem and provide potential repair suggestions.

Thanks,
Dan

SONY KV35S40 Light blinks continuously when power is pressed


hello there,

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.

Sony trinitron


Need a little information here...

1. The TV remains on, yet there is no picture and no sound? Or does the TV turn off altogether?
2. Are the blinks constant and continuous? Meaning, does it blink two times, pause, blink two times and go on and on like that?
3. Can you turn the TV on? Or can you not get it to turn on?

Answer those questions and I can give you some more information or send you to the place where you can get it.

TV won't turn on, red light flashes twice


Fortunately, Sony, of all manufacturers, has built in a diagnostic tool to help you decide what the problem is.

Below is a text on these codes. This is not your model, but the basic diagnosis remains the same. You can count the number of blinks and then look up the problem and solution below:

-----------------
Sony Blinking Codes
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 the 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 eight blinks (depending on the fault) about a third of a second apart, then pauses for 3 seconds, then the two to eight 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. The words in parentheses are those which you will see for each of these faults on a diagnosis screen described later in this article.
Unit is dead and there are 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 As Discussed Above---

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 Vert. Deflection (V STOP), Screen goes to a single
horizontal line then the video signal muted. Check IC1509, Q1505
FIVE Blinks---AKB circuit (AKB), 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. Also unit be in IK blanking,
try turning up screen slightly.
SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
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.
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, Vol 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 problem names is 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.
So, 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
4 times....This would tell you that you have no vertical and that 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, but it's a little better than a poke in the eye with a sharp
stick.
IMPORTANT: after you repair the unit, PLEASE clear the values on this diagnostic screen. These codes do not reset themselves after the fault is 0 corrected, so if you don't clear them, you'll be seeing "old" fault codes the
next time you enter this screen. Clearing is done by going into the service mode ( display, channel, 5, volume plus, then power ) then press 8 and Enter, which of course returns
everything to the factory preset condition.

----------------

As a general rule, the blinking standby light means serious problems and you would be better off getting a technician involved.

This set is a very expensive one and it has some life left in it. Further it is a Sony, so you will be wise to get it fixed.

After studying the blinking codes, let me know if you have any further questions.

Have a great Holiday Season,
Cleggsan
