hey guys, i am new to projection tv's, and i just got a sony kp-53v90 rear projection. got it from a friend that said it worked perfectly until he moved. after he moved in his new place and plugged it up, the picture had/has a red glare. from what i can tell the red has moved out of alignment with the blue and green. when i activate flash focus, the blue and green crosses will line up together and are sharp/clear. the red however, is fat (out of focus) and will not line up with the others. i'm not unfamiliar with electronics, so i figured i'd be able to fix this myself, if i have the right information. any suggestions as to what i should do? does it sound like i have broken parts? or just need to be calibrated? thanks in advance for any help.

bump. i see people looking, no replies? i know someone has to know how to fix this problem.

I could be wrong but it sounds like your convergence is out, this happened with my old CRT rear pro when we moved interstate, Yes the red was about 2 mm say 1/8 of an inch out everywhere in vertical.
I tried the software adjustment and that would not give me enough so I set the software back to 50% and did a hardware adjustment (Adjusted the red Vertical position trimpot and it fixed it perfect. I would say the moving and banging around in the back of the truck moved the Red gun.

ok i adjusted the red converegnce, but it didnt help much. i guess i need to replace the cr board? now ive found the part number, but not sure if when i buy one if it will be complete. and do i have to use the exact part number, as i see that some part numbers are cross referencing other numbers. any help would be great

Convergence (superimposing RGB) and a "fat" red beam are different adjustments. Most CRT RPTVs have a small board with 6 adjustments for both RGB focus and screen voltage (3 each). If some gross tube movement hasn't thrown things too far out, adjusting the red focus pot might narrow the beam again. Take care not to adjust the red screen potentiometer as this will throw off the grayscale setting, likely requiring expert/instrument recalibration. Such adjustments shouldn't be attempted where deadly high voltages are present by those not familiar with safety issues. Sony's focus might be different and a service manual would outline adjustments. -- John
