I have a RCA 56 inch projection t.v. and i got it from a friend. The picture comes in fine but the colors (red, yellow, blue) are visible. Even when there is no picture and the screen is fuzzy the colors are still there.

Re: 56 projection t.v. color problems
If you mean they are separated like a 3-D effect, then you have the typical bad convergence IC problem. There are two IC's mounted on a large metal heatsink, they will have STK392-###, the ### being differant models of TV sets. these are soldered into place and are no usually replaced by the user, unless you have solid state repair experience, knowe how to solder, have a schematic on the set, and know the High voltage safty factors of projection TV serviceing. If you have no experience, please play it safe, and get someone who is trained to service TV sets. Good Luck

If this tv exhibits signs of colors separating ie
when inputs are black screen and menu comes up
then this tv has a convergence issue
there are no stk packs in any ctc chassis made by rca
the power supply board is mounted in the middle of the tv
right behind the crts
it has a red panduit connector on it
if you unplug the power connector to this board and find that your convergence problem hasnt change then the board is no longer providing correction voltage to the convergenece pcb
last i looked the redigned sub for the converge power supply pcb was available with an rca number
lets face it the rca boxes have pictures of dogs on them

Talk to JVC as I have suggested and this is likely a known problem: loss of any color, picture upside down etc requires a upgrade to correct and I have seen about twenty sets with their name like this with this kind of problem.
im joel a simple electroncis tech. try to adjust the settings but it does'nt work the i think 3 color inside ( red,blue,green) is one or two of them is deffective.so the best solution try to go the expert tech nothing else
There may be a number of problems that are causing your HD issues. They may exist in your TV, or in the box you use to tune your channels. Contact your cable or satellite provider and ask them to change out your box. If the condition still surfaces, then you need to have your TV checked. The component and HDMI jacks are both connected to the same electronics. This is why they are exhibiting the same problem.
I have a problem with the colors on my RCA Home Theater model #P60752EB. I believe it to be faulty tubes or something cause my green and my red color is messed up to the point it will not come in at all.what should i do to resolve this problem without replacing the tv
If you are using component cables make sure they are all connected properly( pushed all the way in and in the correct input). I have seen the red cable come loose several times and cause no red color in the picture. When you change the lamp it is easy to pull on one of those cables and cause it to come loose.
I have the same tv set and about 4months ago Ihad the IC STK392-110 replaced. I was told that it was the most common problem with proj. tvs. It did solve the probem until last night when I went into the menu to change a audio setting and stupiditely accesed the convergence setting and decided to do an auto adjustment which mesed up my beutiful HD picture. Now I have the red out of alignment ad even after I did a reset and multiple manual adjustmets it is still off at the top and bottom af my screen.
If the convergence is missing in the menu in screens,you have a bad reg ic on the convergence power supply the part number is 215530,the power supply is located on the black plastic above the right module with all the heat sinks
Not sure if you have the same problem I have but my colors are all off too. I have a 52" projection and from calling RCA with my problem (colors off & have shadows) they said all projection tv's color need to be adjusted every so often (which they do not tell you) after purchasing this tv for $1000.00 13 mos ago I have the same problem. It will be approx. 500.00 to fix the problem and I got no where with the RCA 800 number. A friend of mine had the same problem so I am sure its the same. Good Luck!
