Check whether the filament of CRT glow or not. If not, check all the solder terminals at the CRT base card. If it glows, check all the voltages at the video output card, said above. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts.

Red stand by light blinking continuously black screen


It cannot be reset fully unless it comes on and stays on (the model you have listed here.)

That set should have a blink error code--watch the red power light to see if blinking in a number sequence like 7blinks pause and repeats over and over.

I just got the Sony KV-36XBR250 from a friend of mine. It worked fine at his house. I have since moved it 1 mile down the road and I plugged the satellite cable into the "to converter" port and I don't...


double check your cable routing. The cable that goes into the tv from a satellite box should be "out to tv" or something like that. If you have an old vcr laying around you can test that on channel 3 to the tv. Just in case something broke in the tuner circuit. Hope that helps.

No picture or sound when powered up. Red Standby light flashes continually. My Sony KV 36 XBR250 Wega Trinitron XBR is about 10 years old and has worked perfectly up to this point. What could be the...


Did you get your set fixed or did you replace it? My same set did the same thing. Turned it off for 2-3hrs after watching it and when I tried to power it up- nothing but the sound it would normally make just before the major power up, sort of a relay click sound. No picture or sound but the red light blinks non-stop.

Sony Wega Kv-36XBR250 screen blinking


I have seen this flashing before, this could be an indication that the picture tube is weak, what happens is that if the white balance is off there is a circuit called akb it monitors the kathode of each gun and if they are not in balance it will attempt to balance it out. if it can't the picture will begin to flash, sometimes in some models the power light will blink 5 times. On some models the power light will only flash if the tv gives up trying to compinsate for white balance and shuts off compeletely. If you see the tv shutting off with 5 blinks then you know for sure it is time for a new set.

Blinking picture


TV Repairman came out today to look at my Sony KV-36XBR250 today with the exact same problem - he was able to adjust the settings through the service menu, but said it was a temporary fix only.

The picture tube is going and the Sony circuitry has a "video mute" that it uses when it senses the tube is not warmed up enough. The degraded state of the tube causes the blinking on and off as the signal from the tube wavers.

He ballpark estimated the tube replacement cost well above the price for replacing the set with a 37" LCD, so it's going to the dump...

Picture tube


Ibonne- firstly what is the reasoning for wanting a pix tube" do you have dark picture or poor color. generally when the tube is gone the screen changes to one color.the price of any pix tube is more than the set is worth generally.Please explain problem and maybe I can help you. cooltek Feb.15/08

No picture but sound is good. Screen is black


Do you feel static electricity on the screen when you turn it on? If you do, you have vertical output failure. If you do not, then the likely failure is the high voltage power supply.
