These 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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Red power light LED flashes eight times after turning the TV on and off 3 times. Is this a main board failure?

TV turns red,shuts off, stand-by light blinking 8Times


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.

on.

STEP2 Press the [INFO] button.

The iO button will blink number of times indicating the

number of each digit of the code number. Each digit is

separated by a 1 second interval of the iO button being

turned off.

Example :One blink, three blinks and eight blinks with

an interval of 1 second of iO button being

turned off, indicates the code number 138.


Note :Ten blinks is equal to the number 0.


D. Program the Volume Controls.

By following the steps below, the user can program

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 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
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.

Liz, yes it is a power supply problem, better question is; low voltage or high voltage power supply ? count the blink code, it should repeat the code, once you have the code call your local tv shops and give them the model number of your tv and the blink amount and they`ll tell you price to fix, gl, video-tek

Tv wont turn on


The green light flashing indicates an error code, plasma tv's cannot be repaired at home without the right equipment and service manual, the fault could be power supply, processor or virtually anything, what technicians look for is the frequency of the blinking and the time between sets of blinks, this normally gives the tech a code that enables them to go to the right area, the only thing anyone can tell you is that the processor is probably ok, you really need to get a quote or count the blinking and the timing eg: "blink blink short pause blink), and repost the fault, then we can possibly tell you where to look...Phil

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:

No reply from the jungle IC301 (data bus is busy, shorted to ground or held high), IK video path is defective.

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

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,

Universal remote wont work with this TV


Questions: Who is "Sansui", the digital box ? or the TV? Is the "digital box=remote control"? turn on what you want to control.
Face the RC face down or away from TV,or whatever you want to control. Usually:: push & hold TV & SEARCH button until light blinks, two, three times? FACE THE TV and put the code for the [TV=Sansui ?] You said #189 try 0189 [zero,one,eight,nine]
2nd) TV power ON!,....HOLD down (and if you have a SEARCH) button and the tv power button on RC, two or three blinks, push up arrow once, press power button for TV on RC, nothing!, continue...up arrow, power button. when the TV turns off, you have found the code,. YOU MAY HAVE TO DO THIS 50-150 TIMES because the RC is looking through EVERY code!
