Question about Sony KV-36XBR250 TV
Hi, I recently moved this tv from one house to the next and when I plugged it in, the picture did not come on, but the sound was fine. the stand-by light is continuously blinking but the screen is black? It was cold outside and the tv was outside for awhile, would that have anything to do with it? Please help, would hate to throw it away...
It seems that your tv has a problem in horizontal circuit (with sound but no pictures). since you moved your tv from one place to another, the tv might have shaken causing to loose some soldered components particularly in horizontal circuit. if u have exprience in this stuffs, try to resolder the circuit, if not, bring it to a service technician.

I also have this problem. my tv was on most days and nearly all day. then i had to decorate. i took great care in moving it and when everything was put back i had no picture but i did have sound. i have tried everything but i do not get anything on the display. it seems to be working in a way as the screen lights up but there is nothing even menu functions or mute diagram that normally appears on screen even without an input signal. if anyone has an idea other than those posted. please help. This is the second tv that i have had this problem with and the first was replaced.
32" Wharfedale Lcd TV.

If the standby light is continously blinking..try to press any button if no response then open the unit and try to resolder loss connection..

The light is flashing a fault code, count the number of flashes (ie blinks 3 times and then pauses) then search the internet, there is more than enough information. Just search Sony LED blinks/flashes. As you have moved the telly this could have also loosened a poor joint inside, stopping the telly working properly. No dont put the aerial cable into the video sockets, you had it right the first time.

I think it does have a lot to do with loose solder. I hit the side of mine at it just came back on. That sort of thing is usually dry solder jumping out of place.

Mines different its just an old box tv not a lcd it hasn't been moved but it works for 5 minutes then just seems to go on standby but with the sound still working, my family seem to think its something with having a sky+ box installed but i differ

I had the same problem. isolated the issue to the televisions coaxial input. used red/white/yellow cords directly and it seems to work fine

I had the same problem with the same TV. The pic would come on and then go black on its own or when the side of the case was touched. I took it to a certified Sony repair shop...they had it for a month and got it to show the problem only once in their shop; thus, they could not provide a diagnosis. They claim they haven't ever heard of this problem before, but obviously its happened to many others as well. Long story short, I took the TV back home and haven't had any trouble since (who knows???)

Any luck with your problem? I have the same thing going on with the same tv.

Interestingly, I just had the exact same problem last night. Let me know if you figure it out. Actually, I got the picture to show up one time. But other than that it seems like it might have something to due with the connection to the tube. Using car terminology, is it almost like the picture tube won't "turn over"? That's what I'm experiencing. I will let you know if I find anything

No I haven't had any luck at all, it seems that the only way to fix it is to take it to a repair shop, which is easier said than done in Telluride, Co. Good luck...

Ski Bum, I have the exact same problem with my TV -- sound is fine but no picture. Was wondering if you had any success with resolving the issue? Snoop

I have the same prob. almost! no picture just sound. Standby light blinks for ever, on my sony kv35s66.. temp. fix is remove back cover, lossen plastic clip that holds the large circuit board on the bottom left as you face tv from the rear. Move the bd. out 4 " then slam it in(hard).. picture will come on but will fail again (intermitten) To have some on try to fix it$$$$$. and they probably won't. again this is only temp still working on the problem..

If you moved the set you have to open the back of the set. and check all the boards, maybe one came off, press the boards in place, also connections may got loosen.

I had a similar problem with a TV a few years ago, whereby the coaxial connection was damaged. I used the RCA jack inputs instead and it worked fine. Hope that it is something simple like this!

We have the exact same problem as skibum describes.

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.

My picture would go out after several minutes but I still had sound. I took the rear cover off and blew all the dust off with compresed air.I did this for a few times over several days nothing happened.I also took off the rear circuit board that attaches to the tube with a round pin socket and blew that with compressed air and put it back on. The TV has now worked for two days without the picture going out. It worked!!!!!!!!!!!!!! My TV is 9 years old.

SOURCE: TV does not turn on
On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.
