Question about RCA HD52W56 52" Rear Projection HDTV
Red, blue, and green lines. looks almost like 3D picture.
This is an ITC222 chassis. Very common for broken pins under flyback to cause this. Resolder flyback and replace adjacent 400ma fuse. It's a little red box, there are 3 in a row and the one that blows is the middle one. If this does not repair, suspect the convergence power supply. It's the vertical board above the power supply. I've replaced the power mosfet on that a few times as well. And remember if there's any doubt contact a professional. Goodluck.

you need to replace both convergence ic's they are located on your D board mounted right on the 2 big heat sinks you should either need STK-392-560 or STK392-510's you can find which one on stamped on the side of your old ic's. you can go to this sight and get them at reasonable prices plus picture installation instructions and free online tech support if you need help. By doing the repair yourself you will save between 4-500.00 for about a 45min repair

Hi there, this is what we call in the industry convergence board failure. this board regulate the rgb and keeps everything in order so the picture looks nice and clean. when this board starts to malfunction, what you are witnessing is usually the result. I suggest repairing this convergence board. this will fix the 3-d effect.

The vertical deflection output chip or associated cirutry including the coupling cap and controls. Some units have vertical output transistors which can short and open the B+ resistor feeding the transistors.

This is symptom of convergence output chips failure in rear projection tv, replace convergence ouput ICs in tv to get it fixed.
If you are handy with electronics stuff repair and can solder parts in circuit board then check 2 big black ICs mounted with aluminum heat sink on D board of tv, replace them with same numbers and if you feel uncomfortable working with tv circuit boards, local tech will help you.
