Convergence problem on RCA HDTV

My tv is about 1.5 years old and has recently started unaligning randomly while it is on. What i mean is that red, green, and blue are all off by about 3 inches and form 3 lines accross the screen. Turning off the tv and letting it sit sometimes fixes it, and sometimes it just fixes by itself. It is connected via the hdmi port and now also to the component connection with no help. From what i have read it could be the convergence chip? I was wondering if anybody believes this to be so and where i could get a chip number for it and/or any other parts that might be bad.

What is the model and chassis number for your set? Te chassis number is most important to diagnose a RCA set. Please post the chassis number located on the rear panel of the set.

    Due to the fact that it fixes itself at times leads me to believe the ICs themselves probably just need soldering. I would try that first before replacing the ICs. ust be careful not to bidge any of the pins with solder while resoldering. Check your work with a magnifying glass before you power it up.Let me know if yo still need the IC numbers.

If you have the original remote to that tv, click on menu, then select set up from the on screen menu, then select convergence. you might see auto convergence as well as manual for blue and red convergence.

If you see Auto, select it, this will line up your tubes.

If no auto convergence, you will have to select each one, and follow the instructions to aline your tubes.

Hi. My Sony Videoscope XBR's Convergence Allignment


I happen to share this same problem. The alignment of the gridlines on the standard convergence panel are completely abnormal, and if I attempt to auto-adjust the TV, it flashes different colors on the sides of the screen , and then turns off the convergence settings.

This problem is commonly refered to as a CONVERGENCE problem. Question 1 do you have convergence seting in setup menu...if you do NOT it could be a special small fuse. 2 if you go into setup then convergence. then can you move crosshairs in setup. Since you have a arcing picture this indicates convergence power supply problems....in which has to be replaced or repaired,
