Bush tv, screen has gone blank with no sound or picture. Fuzzy noise in the back ground. Sometimes takes up half hour to come on but today no noise / no picture just blank screen, any advise on the issue...


I think it is Time for a NEW TV. Not worth the money to repair. If it is under warranty, have the work done but other than that, you are wasting your money

Sony Trinitron model # KV-27HFR- the picture is fading, is there a way i can fix that?


From your descrition the problem is the picture tube, over a period of time the guns build up crud reducing the emission on the front screen which in turn causes fading and progressively gets worse until viewing becomes impossible. One possible solution is to have the picture tube rejuvinated by a tv tech to buy more time out of the set, but the improvement may last a few days to several months or more.

FADING TO BLUE SCREEN


Sounds like you have a problem with the blue gun in your picture tube or its drive circuit. You might remove the back cover and gently tap on the neck of the picture tube using a plastic screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem. If this is a projection tv you have three separate tubes : red, green & blue. you'd need to tap the blut one.Gently!!!! Stargazer

KEEP FADING TO BRIGHT BLUE SCREEN


I'm about 90% sure it is the blue picture tube developing an intermittent heater to cathode short. I'm surprised the set isn't shutting down shortly after this happens. A service call will tell you for sure as it could also be a bad solder connection causing a similar symptom. My own procedure to check it out would be to GENTLY tap the neck of the suspected picture tube with a screwdriver handle to see if I could get it to come and go (Or get out my CRT tester and measure it with the power off). Obviously by holding the screwdriver blade you don't want to accidently short anything out as there is about 33,000 volts a few inches away from where I would be tapping. Nuff Said.
