Blue convergence on Pioneer SD-532HD5

Hi, After 7 great years, my Pioneer gave me a problem with blue convergence. It can't be adjusted, and creates lower ghost image on the screen. I am outside of Pionneer's service area, and was wondering what convergence IC(s) (part numbers etc) can I order on-line to replace the faulty ones? Your help is greatly appreciated!

If you are going to replace these IC's that are only 8 bucks, you will most likely be having the same problem down the road in the near future. You should not buy the cheap replacement IC's my friend. If the IC's do not say Sanyo on them, they are generic, and do not meet the specs. of the manufacture. Good Luck

The converence IC's are the problem. Unfortunaely, I do not a service manual for that unit. You will find the IC's mounted on a large heat sink. The nuers usually start with STK-xxxx. Find these IC's and copy the number off them. Usually the can be replaced by generics. You can order them directly from Mat Electronics 1-800-628-1118. Be extremely careful when you desolder these ICS the foils are easy to lift. Use desoldering braid(chemtronics) 10-25L. Also ask for BOB and tell him that Tom from TOM's Tv suggested him. This will insure you the lowest price. Also some times the current limiting resistors open up. Always replace both convergence ICS. In your case only one is bad. Replace both anyway. (they only cost about $12.00 @ Any further questions, contact me. These are great TV's and well worth repairing!!! Scrivitron

Blue convergence will not align...model SD-P5181

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.

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.

I have a pioneer SD-532HD5, the red convergence went wacko and cannot adjust

A microchip controls the color convergence. There is no easy way to fix it. A new chip will be needed.

Sounds like you lost the converigence. Have you tried to realign the convergence through the user menu? Try that first and see what happens.

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.

This fault happens with just about any tube type projection set. The convergence IC's simply need to be replaced. They are two black, 2"X3", stand up ICs that will start with the letters STK on the surface of them and are mounted up against a large metal heatsink. If you have the soldering skills this should not be so hard for you to do, but please if you do not have the skills or experience to replace these IC's call in a pro to assist you with this repair. Good Luck
