This is an indication that you have a problem on the power supply section or on the load because of the following reasons :

1. Over Voltage - the regulator might be cycling on over voltage due to lack of load.

2. Over Current Protection - excessive load or faulty power supply cycling will

trigger the over current protection circuit.

3. High voltage - there might be an excessive high voltage or some other system detecting an out of regulation condition. However, in this case, there should be some indication that the deflection and HV is attempting to come up - momentary whine, static on the screen, etc.

4. Leaky Capacitor - a dried up main filter capacitor or other filter capacitor in the low voltage power supply that is producing an out-of-regulation condition. A bad filter capacitor on the output of a series regulator may result in excessive/drop of voltage causes your unit not to power up unless isolated.

5. A problem with the microcontroller, relay or its driver, or standby power supply.

This is not DIY and quite technical so I've advice you to look for a qualified technician or send it to repair shop to isolate the problem.

Thanks for using fixya.

Please rate my help.

it might be dust build up if it has been in a dusty house. tvs collect dust easy it my need to be cleaned or it could be the fuse is not getting a good connection or maybe getting ready to blow, it could be either in my mind. Hope this helps

I had the same problem. I took off the back and blew out the dust with compressed air, and it came back on.

HEllo,
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hope this help out in solving the problem....

• 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.
  

Hope that helps.

If you have a universal remote you should be able to get into the menu system and select the AUDIO tab. From there you should be able to select STEREO/MONO/SAP

I sent a premium offer to solve tv issue but got no response so far, not sure why.
I'm Sony tech and can be helpful to resolve this problem.

Go to Menu Settings Picture Check the the picture settings Select the format which fits on your screen OK/Save the settings.

Everything is controlled from your computer. If you need to go to the main screen of your computer, right-click, go to properties, go to settings.
You will see two boxes. Box 1 and box 2. Click and drag box #2 to the left side of box #1, then click apply, and click ok.
You should now see your main screen picture on your tv.
Now, whatever program you open on your computer, you can drag the entire frame over to the tv screen.

this symptom is usually caused by a breakdown in power supply circuit or it may also be caused by a breakdown in the horizontal deflection circuits which includes horizontal oscillator, pre drive or drive circuits, horizontal output transformer, horizontal output transistor and high voltage circuits (flyback transformer). pls observe precautions in dealing with this high voltage circuits and if so happen you are not inclined with this kind of work, it is better for you to bring it to a qualified technician to avoid accident. good luck!

Hi,
I need more detail about "tiled" picture to diagnose the problem.
Did you tried dvd player or any other video source on this tv to see its picture result/ quality?
Thanks.

it look like you have a missing voltage on CRT board check the 9v, 200v or 115 and heater voltage?

ONE: Unplug it for at least 4 hours. That is what we call a hard reset.

TWO: If the hard reset does not help, then it will need further diagnostics.

The following bulletin may be of help in your learning about what is going on. Please refer to it below. Then let me know if you need further assistance.

Have a great day,

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
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.

I HAVE A SONY CRT TV, BUT THE TUBE IS BROKEN. i BELIEVED. THE TV IS

Above Sony support, below is a service and repair manual This is a classic switchmode power supply, shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an Akai, Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free.

It appears that on this television you can only adjust the picture size when you are using the twin picture feature. You must adjust the picture size with your other remote control. Since I do not know whether you are connected to a cable box or a satellite tv box or a blu ray player or a DVD player I cannot be very specific. On your other remote control you should had an hd zoom button, aspect, format, ratio, #, or etc. Those buttons change the picture size. The other factor determining picture size is the resolution the equipment connected to your tv is set to. This tv supports 1080i but you should also try setting the connected equipment to 720p or 480p or 480i. Also the connected equipment may be connected to your tv in two places so make sure you are on the correct selection using the tv video button on the Sony remote.

short the prongs. then plug again.

Hi mopargerlitz
I`m going to help you with your tv but i`d like to know what you mean by"red was separated for some time"
Do you mean that the red was flaring or smearing over the other colors?
Does it take longer now for the picture to appear?

I have one for sale.
