Older RCA Projection screen, Blue picture!

it sounds like the picture or screen is on the fritz. some are worth fixing. you are prolly looking a $700.00 or more to fix it.

I'm not familiar with this set but it sounds like your blue crt has shorted out and is putting out so much color that it overwhelms the other colors. Is the picture also washed out? If so then your blue crt is bad. Probably not worth fixing. Let me know more about what the picture looks like.

Hi

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.

Thanks

Almost certainly the blue picture tube is bad. This is a huge job to replace and quite expensive. Generally it is not worth doing.

the color in my tv is a little faded when theres dark scenes on cant really see picture. Red and Blue really fade into picture

Sounds like a bad blue CRT (picture tube) ITs expensive and difficult to replace. CAll a Sony service center for an estimate. but expect to spend $500-700 to replace it.

Go to menu look for convergence on menu if it is not on menu then you have a open fuse located next to Flyback Transfomer on deflection board.

it can be replaced with a t0220 stile case dioded 220k ohm go to nte look up and do a search on the rca part # 259638 search the web for the part.

The blue filter is burnt out. A very common problem in Zenith DLPs. There are 3 color filters, 1 blue (a pinkish color), 1 green (a grayish brown) and 1 red (it is red) they give you your colors for you picture. This is a simple fix.

Change the coolant in the blue CRT and your picture will be new looking again. Let me know if you need more information.
