    People have red eye. and are kind of out of focus . Convergence settings move around . Is this a problem with the convergence board? If so How do you repair this from start to finish? Thanks ' Larry C

I would guess that the top and bottom of the picture is pulled toward the center of the screen as well. This is a convergence problem. If you can solder, you should be able to repair this yourself. If you wish to attempt this repair, please update this and I will provide more details and instructions.

Thanks,
Dan

turn the center dial ( for green) down slightly then turn the other two the red and the blue up slightly to get the best screen without a dominate color screen.

My projection tv lost its blue tint


Hi

Thanks for using FixYa. Usually this happens when the Light Engine has gone bad, and I should say this is a common issue with Projection TVs. There are three tubes/mini LCDs inside your TV- green/yellow, blue and red. When the set heats up over time of usage the screens tend to break resulting in leaking color everywhere. The cost to get this fixed by a professional should be around $300 depending on the parts that needs to be replaced. Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

No Red color at all. The convergence feature does not work either. Lots of green and blue RCA Model D52W59


Red color gun has failed, which will make the picture over saturated with the other two colors(blue,green) the bad news is the three color guns need to be replace in a set(all at the same time) because if you only replace the red it will over saturate the older blue, green guns then your picture will be mostly red.Unfortunently in most cases it's not worth the investment, better off to purchase a new tv. Good luck !

I heard a pop in the TV and then the screen went red. I can still hear it and watch it but everything is red. Is it a bulb that needs replacing? If not, what is it? Can I do it myself or will I have to...


Several failures can cause a red picture but it sounds like if you are connected from the source with component video cables(red,blue,green)you may just have a bad cable,but you may have had a blue and/ or green projection gun failure,which would cause the red gun to over power the other colors(blue/green), if this is the case definently not worth the cost to repair, you have to replace all three guns at the same time costing $500+ to repair, invest that towards a nice new LCD panel TV. Good luck !

3 screen colors have separated and screen is bowed in the middle.


I take it this is a projection TV. so they use three lensed CRTs red green and blue. you should have a setup screen that projects a grid pattern. red green and blue. there is SOMEWHERE a adjustment that overlaps the three projected grid patterns. Making a WHITE single grid pattern. red green and blue make white light. Pin cushioning is the bowing. you may find a POT to adjust on the back of the set. I have no idea what set you have.
Lastly.. Pin cushioning can also be caused by faulty flyback transformers.
Hope I could help.. new here LOL
Happy Fixing =)

i have an alinemenet problem with my rca tv P52929 i went to the book and it said to go to the menu and select 3 which is the screen menu then select option 6 which is the adjust projection tv. this is suppose to allow you to adjust the the tv's three colors. it says to select the green centering to adjust the green tube. blue for the blue and red for the red. it says to center the green first then adjust the red and blue tubes until the test pattern on the tv screen appears white. i hope this helps you. my problem is that the program is not in my tv. it has everything else but not the option 6 to adjust the tv. this may be your problem to. good luck.
