Sony 32" xbr trinitron trusurround T V picture is black

Most likely on a trinitron tube if it is dark is the high voltage capacitor has blown. This is the device that feed the 30,000 or so volts to charge the tube, it attaches at the back with a clip and ****** and a single cable coming from it.

You can check easily if it is definately that as you will notice if you power the tv on and off once or twice if you get that static charge feel from the screen, if there is none there then almost certainly that is the problem.

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.

My tv blinks from regular picture to a black screen continuously.

your tv is on the blink.

remove the back panel of set
on the crt pcb board you will find a wite or black pot.
turn it up or down while set is on this is the G@ voltage ajustment.
you might get 3 monts to a year of extra life from your pictor tube by doing this.

Blinking STANDBY Light front of Television

Refere to Sony Blinking Codes :

Sony kv35s66: No picture, just sound and red blinking

The most common problem (I have fixed lots) is the Vertical amplifier has developed a loose connection. It probably just needs resoldering. As things expand it makes and looses connection you picture goes in and out. The vertical chip is a large black chip that gets hot, over time it degrades the solder until a connection is damaged. Most newer sets have a protection circuit that senses the lack of height, and shuts down the picture tube to save it. When the picture dropped to a line on older TVs and left that way too long it would burn a line into the face of the picture tube. You then had to have the picture tube replaced along with the vertical amp. it's kinda like a screensaver for your TV.

Sony Trinitron KV-32S40 32" TV problem

This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.

My tv blinks from black screen to picture

You might have loose conections on the horizontal driver or output circuit,do not use it like that or it will go dead completely and is going to cost a lot more.If the set is older than 5 years it might have loose conections in the power supply too.Call someone qualified for an estimate.
