Mine blinks like 5 or 6 times - picture goes out, but sound stays. It has been at the repair shop for 1.5 months and the tech finally sees the problem. He says 3 new tubes will fix it, but the blue is discontinued. Can anyone confirm?
Hello - I had the same problem. If you call a tech they will say that
the picture tube is broken and that it will cost $350 + labor to fix it
because Sony does not make the part! Do not believe that cock and bull
All you need to do it to remove the front lower panel
where the speakers are located. Behind it there is a cardboard /
plywood board fixed on to the TV with 4 screws. Remove this board. you
will then find a switch that contains 6 bolts/screws that can be
adjusted:- 3 (upper) and 3 (lower) sets of adjustment knobs or large
screws that are probably marked as G(for green), R(for red) and B(for
blue). You will probably have to adjust them very slightly while the TV
is on. Be careful so that you dont shock your self! And Voila, the
problem will be fixed!!

Re: am i screwed
No, not screwed, but you will need it repaired...
Sounds like convergence issue and possibly ring-cracks on the amps themselves until the heat and vibration did them in..
Now the shutdown circuit won't let you power-up the set...
This unit uses two STK392-020 Sanyo built amps. Those, together with testing and replacing some low ohm resistors should have this unit up and running again in short order...

HERE is a answer I remember seeing on a site that charges for answers:There are a couple of different things
that could cause the 6 blink in your model, the first is the power
supply, and the second the main board. Also either sustain or scan
driver board can cause this problem.
know exactly what board is the cause, you need to have electronic
repair experience, and test equipment. If you have this let me know and I
will assist you in the troubleshooting of this tv. Otherwise you will
need a repairman at this point.
You can expect a bill of anywhere between $300-$400, this is a good average, however it could be more or less.
I am sorry I don't have a quick fix or easy answer for you on this one
This is simple--this model is prone to bad picture tubes--blue is most common--screen goes bright blue and set shuts off--set is detecting too much current being drawn--forget replacing the tube--very expensive as only available on rebuild basis.
Here is what to try: 1) you need to remove entire plastic grill under screen--held in one of two ways--either several screws on back on either side or two screws at bottom front under caps.
2) With it free, pull up from bottom and tilt entire grill to the left--the front controls are mounted in it and you will need to undo some ties that hold it to get it out of the way.
3.) Grill has tabs at top that tuck in and you lift it from bottom.
4.) Remove small inspection plate behind grill--a few screws.
5.) Directly behind grill you will find a square black plastic block with 6 shafts (they are controls) One row left to right will be marked Focus--do not touch those. The other row will be marked screens. Look closely (green is the middle one) as each will have r,g,b in small black letters.
6.) In your case LOCATE THE BLUE SCREEN CONTROL. Best way to do this is take set to unused video input and turn blue SCREEN down (usually to the left and less than 1/4 turn) until the blue just goes away---on blank input you should only see VIDEO 1 etc in green.
Do not turn down too much--just enough so blue is not there--no blue background or curved lines.
THIS MAY ONLY BUY SO EXTRA LIFE OUT THE SET AS ALL THESE HAD ALL THREE TUBES HAVE THIS PROBLEM.
You only have seconds if the set is shutting down, Once you get the blue down enough set will stay on.
Take to regular channel and with color all the way off--you should have a black and white screen, adjust just a little if needed.
I have done this many times and most get another year or more out of the set--if one of the tubes is causing this (very likely) sooner or later it may get worse and return to the point where adjusting does not help--when this happens replace the set.
If this has told you something that helps you or you did not know rate this solution as very helpful as I do this here for free.
If you have questions let me know BEFORE you attempt it.
Hello: Have you tried to adjust you Green Screen control on the focus block assembly. located behind the front panel assembly. Here is a solution that might help you, turn off the green by turning off this control, make sure u look at the block and make sure you are not turning the green focus knob instead of scrn crl. Turning the control slowly to the left the retrace lines should disappear as the green video darkens. Then turn the control slowly to the right just until the retrace lines reappear, then turn back slowly left just until the lines go away. If the screen is Blanking on green tube only then you have a video blanking problem on the main signal board. Or possibly a IK bias problem. It is also possible that the green CRT is defective. The FBT is not bad because the screens are lighting up indicating you have high voltageand heater voltage which is derived from one of the secondary windings of the FB. If it is a Blanking problem i would look into replacing the A Board assembly.
you need to make sure all screws are in and tight , and most important the cover on the back of the tv were you access the lamp that has to be on. There is a little blue plastic piece (the safety switch) if that is not engaged the tv will stay on fore a few seconds then turn off check it out.

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance: 1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours 2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris. 3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle
Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!
The flashing light is giving you an error code as there has been some sort of failure in the TV. The buzzing sound could be the flyback transformer. Count the number of flashes. I'm sure the code will be for the flyback.
ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN. PRIDAH
