RCA P52937SG Convergence (by 7 users)

posted by AuntDrea on Jan 29, 2008


I have a RCA P52937SG that is having a convergence problem (from what I have read online). All edges are bowed in, and I cannot align red/green/blue. In the menu selection for "green centering", the green line is at the bottom of the screen and curved (due to the bowing).

I live in a rural area and am looking at having to pay well above standard rates to get this repaired (due to the distance from repair shops). I have found instructions on the web to do this yourself for other models, but not mine. I believe I can do this myself with proper instructions, as I have been a computer technician for many years.

Can anyone help me become a TV tech as well by giving some instructions? I have already had the TV apart once, but really just to take a look around and see if I could find any obvious problems!

Thanks!

Thanks ctf1800, I saw some of these same links on another solution you posted, however, I took it apart again tonight and I can't for the life of me find the convergence board or IC chips! Any clue as to where they are located on this TV?

Thanks again!

Sorry, I don't mean to be naive, but I don't know what this means...(???)

Same issue. The image looks bowed and all three colours are out alignment. This happened suddenly, from one day to the next, without any preamble or symptoms.
