Question about Pioneer SD-P50A5-K 50" Rear Projection Television

1 Answer

Need to help accessing convergence IC's on Pioneer SD-P5191-k

I am having convergence problems, I am going to try to fix it myself after finding courage with reading through the posts in this site, besides , can't afford the tech estimate of 400 bucks. However I am having problem getting access on the convergence IC's. I have been having trouble because of the tight space and I can't seem to get the A board out, I was able to find the screws to the whole thing, but the cables and connectors prevents me from taking the whole mainboard out. If I could have some guidance on how to get access and how to get the IC's out OR by just taking the whole heatsink without taking out the whole mainboard. tnks

I HAVE A PIONEER 50' TV AND THE TV REPAIR MAN WORKED ON THE COLOR CONVERGENCE AND NOW HE SAYS THAT I HAVE TO FINE TUNE IT? the main problem was the blue line.


YOU need to have the original Pioneer remote to do this--I do not understand if someone fixed and you had the remote why he did not adjust it?

With the Pioneer remote you go into the customer menu and adjust convergence--most also have a TECH menu for this but you still need the remote and a code to get into this--REMOTES FOR THESE SETS ARE HARD TO FIND AND EXPENSIVE.

Let me know if you have questions--I am here to help.

Right side convergence


A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.
