If you still have the sound when the picture blanks out you might have a weak picture tube . Are the colors bright or somewhat weak . If they are its the picture tube . Now if it has good color and brightness then you may have a loose connection in the set or something wrong in the video circuit . Older sony tv tend to have weak picture tubes .

My Sony tv screen blinks off and on and timer/standby blinks 5


Yes....this blinking code is a diagnostic fault code which is a good thing, you count the number of blinks and it tells you where the problem is.....you also can see it by pressing the buttons, DISPLAY,CHANNEL,5,volume - not + ,then power....In your case it blinks 5 times,its in the video out,you need a desoldering iron,solder,rosin core 60%tin and 40%lead...remove and replace these,Q761,Q705,Q732 on the C board also Q218,Q219,Q220 on the A board.hope this helps.......

Blacks out for 1-30 min. then back on. Standby light blinks 4x


I would suspect the circuit board around the HV transformer area to have a crack circuit print. Also look around in the vertical circuit for interment solder connections. But only do these things if you have some knowledge of TV circuit lay out. If you do not feel confident then call a professional. No sense in hurting yourself or damaging the the set worse.
Hope this helps,

Blinking a black screen on and off.


Picture tubes do not "go out" by going black: Your TV has a power heat-related issue. It is trying to come on but, the protection circuit is preventing it.
As; opening it to dust it, is dangerous; I suggest you take it to a good tv shop.

Sony 42" KV-32S66: picture blinks off briefly, getting worse


your crt is getting weak you can get around this buy adjusting the screen control ...... the screen control is on the small board on the back of the picture tube . remove back , with picture tube flashing adjust screen control a touch one way will make it worse and the other will stop the flashing . only move it as much as you need to - no more . this will work for a while and you can do it again and again when ever needed . but the picture will not be as good .... as far as the free dead sony , i would get it . changeing a picture tube from doner tv is just plug and play on a sony . so you can have a new tv for free with just a little work ..........if this answer helped please rate it 3 or 4 stars . a high rateing will help keep mein the paid answer department thanks

Blinking picture until warmup


On Sony TV's they monitor the current drain on all three electron guns Red Green and Blue. Until all are somewhat equal it will keep the CRT blank. As the set ages it means that it might flash a few times until the cathodes are good and warmed up.
