If your TV works for an hour or so then it is probably not a connection problem. It sounds like a component is heating up or there is a problem with your picture tube. Make sure the TV has enough ventilation around it but it maybe time to think about getting a new one.

MY TV PICTURE HAS GONE A LITTLE DARKER AND ADJUSTING BRIGHT, CONTRAST, COLOR,ETC. DOES NOT HELP


How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.

Hello, why does my plasma tv have thousands of red and green flashing dots all over the dark parts of screen after it has been on for roughly half an hour? if i turn tv off for a while then turn back on...


I had a similar problem but mine was just red specks that showed up in dark scenes. I opened up my plasma and found the adjustment pots that are labeled Vsc, Vy. I then marked the factory default with a sharpie first. Then I lowered the Vy a little and my red specks disappeared. Now my tv looks awsome again like it was new.

Screen doesnt work, sound works fine. It worked fine last night but wouldnt turn on this morning, why?


is the screen dark?, if is it, see if the TRC filament is light, if is it afirmative, turn a little clockwise the fly back knob that say SCREEN and watch if there is a horizontal line at midle of the tv screen. if is it, your problem is in the vertical stage.

Brightness of picture


If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.

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
