You definitely have bad solder grounds. I have repaired a few of these. You will need a TV tech pull the boards out and resolder them. The worst board would be the one on the left [signal board, has rca jacks. rf connector]. And they may as well solder the second board. You will have a restored TV when completed. Thanks for asking and show a few hands of support!

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.

Just tonight we were watching TV and the screen got darker. Picture is still fine, just got darker, on some channels the top and bottom center bow in toward the center a little, easy fix or a lot of...


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.pnghttp://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Screen dim, black has green in it, contrast and brightness = shin


Since you have replaced the Color Wheel, it sounds like you have not adjusted the Index Delay in the service menu. First reset all of the picture settings you have adjusted back to original factory settings. Then on your Samsung TV Remote and with the TV OFF, Press Mute,Power,123. This will turn on the set and put you in the Service menu. Look for the top setting and select or scroll to the OPTION setting and select and look for INDEX DELAY and select that. Once you have the Index Delay selected use the right and left buttons on the remote to adjust for a picture the has no abnormal coloring and while looking at a program adjust for when the blacks look black with no abnormal coloring. Once that is done, turn off the set then turn the set back on. Now the picture should look normal.

TV turns on, but picture is red/black


you can try the main board and the control board first (this is the lesser of two evils), if that doesn't do it, it's definitely your sustainer board is bad.

Dominant blue


Can you post to the party who has too much green how to adjust the video adjustments? They need to know so they can see if
its just a simple adjustment.
In your case, first turn the color level clear down to where you
have a black and white picture. As in the case of too much green,
question is if the picture is black and white or if there is a color
on the screen so its blue and white? I suspect it will be which
is typical when the guns start to fail. Likely the green and red
guns are weak in output. There are screen adjustments in the set that a tech can set up that may help some, but the only real fix is to replace the guns which is expensive and requires a complete allignment. All 3 guns need changing to get it back to spec and it is a good idea to replace the flyback for reliability. Get an estimate and likely you can replace the set for the same money.

The picture tubes dim over time. It's possible they need to be replaced and/or cleaned. There are 3 of them (one blue, one red, and one green).
