Adjust picture tubes

I have the RCA MM61110 it works fine after replaceing three picture tubes. Unless I use the high def, The outer part of the picture is fuzzy on all four sides. I had a tech there but could not figure it out. I think he just sucked. Is there a way to adjust the tubes. I know there is an option from the menu to adjust the picture but not the way it needs to be adjusted. Any info would help.

If all 3 crt's were replaced it sounds like something was not reassembled properly. There is a chance that the mech. focus on the crt lens need to be adjusted, or the mirror is not in the right position or it is possible that the convergence is not properly aligned. If you can send me a digital picture to: lap9728@msn.com I can probably give you more info.

My rca hdtv does not have picture only voice


Some possible causes:

No filament voltage to the three tubes.

No high voltage to the tubes.

The set is also prone to bad connections at and around the high voltage transformer.

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...


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

Picture tube replacement in these set can be high. and most of the time unless the set is under warrenty to costly to get fix. From my point of view( a technician) i repair these set alot. and the tube runs 250 and then labor is very extensive. i think we repair a tube for about 350

Picture format



The HD reciever shouldn't be the problem.

If you recieve an image with a 4:3 aspect ratio, the image will be displayed at that ratio on your HDTV unless you specify otherwise. To do so go to your TV's Setup screen

setup
Choose picture formats
select smooth wide as your default

***Some digital (ATSC format) stations may transmit 4:3 images in a way that will not allow expansion. You will be unable to adjust the picture format.

Hope this helps!!!

RCA MM61110 Problems


I took the back panel off and noticed that one of the cooling fans was not working..... apparently the computer tells the tv that it will not be able to cool. I cleaned things using air and basically followed the wires for the cooling fan and wiggled them... lol.. works fine now

No high voltage to the Three picture tube guns. The high voltage splitter could be defective. You have audio but no video I presume.
