Why does my tv have one blue, one red and one green line at the top of the screen but no picture?

The CRT inside the TV has gone bad. You can either find the make and model of the CRT and replace it, or get rid of the tv and buy another one.

Our 1991 RCA P52150CP rear projection TV has gradually been getting bright cloudy blue, slight haze around letters & shapes-(especially blue channel change headings) when first turned on and then it...


First check whether all the cables from your dishnetwork are fine and connected firmly.If yes then you'll need to pull off the front of the tv, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. so we are doing real small adjustments. Turn the color off on the tv and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

And, if it doesn't resolve your issue then it is an intermittant blue picture tube, a bad blue driver transistor on the CRT board, a bad connection on the blue crt board, or a problem in the RGB coming from the video jungle IC. A set this age, most likely will run you about 300 to 500 bucks to have this problem fixed, unless it is the picture tube.

Please do accept this solution and revert for further assistance.

cheap,,easy way is spend $3 extra a month to have your cable Co repair or replace any seeping cables or adaptors and/or splitters.

Sony KF50WE610 Vertical Blue Lines Across Screen

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

TV turned off itself

Can you still turn it on?
If so, does it stay on with sound?

If the sound is ok and the picture is blue (even when changing channels, inputs, etc.) the lamp may have gone out.

Can you see the TV menu when you press the menu button on the remote or TV?

Blue flashes on screen and then just quits

post your model. Sounds like the blue CRT is shorted. But let me know the model and I will let you know how to test it.

Is the blue line running straight across the middle of your screen? If so its a vertical deflection problem. Possible bad Vertical output IC

Multiple problems, hoping for one solution

sounds like it is probably worth trying to degauss check this excellent site; for details of how to try this on the cheap - it works If it doesnt solve your problem, the fact that you are getting different quality from different crt s suggests that they could be the root cause - see if you can get the part number, and get a price you may find it is cheap enough to be worth trying - check also the power supply - poor voltage output can sometimes cause these type of symptoms. Hope this helps, if not post again - some of the other guys know tvs much better than me :)
