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

Right side convergence

Hi! I have a Pioneer sd-p4553. Picture has always been great. Few problems I have fixed my self such as loose resistors, etc. Annually clean guns and mirror and remove dust from boards. Have just noticed that the blue convergence on the far rightside is off (about 2 inches of screen) only noticeable on white type. Convergence line up is OK except for a little tail on the blue only on right side. IC's need to be replaced? If so, part#'s. thanks for your time. jgs

More likely an alignment issue.Ic replacement alone may not complete the repair.

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.

Sounds like the gun is trying to fire up but has internal problems. You may want to see if you want to tackle the job of changing it out. Check with MCM Electronics to see cost of a new gun. 1-800-543-4330 or www.mcmelectronics.com

PIoneer SD-643HD5

yes ,you need to replace both STK392-110s,or 120s,i always upgrade to STK392-180s.These are your convergence ics and you do need a service techician in order to fix this". after replacing both ics you have to realine complete convergence your looking at anywhere from 285.00 -350.00 depends on labor.one lady on here was told cost of repair on her set was 700.00 she has same problem.thats where she lives different prices from state to state.

Pioneer sd-p5071-k intermintently turns off, when on its works beautifully

You may need the power supply board resoldered as I had the same problem. The guy listed below can do it for you as I shipped mine from Illinois to him in California... Piece of cake getting the board out of the back and it's not too fraigile... Just pack in bubble wrap and it will be fine. My TV is now working great.

BUT DON'T DELAY AS SOONER LATER TV WILL NOT RESTART..

Blue convergence on Pioneer SD-532HD5

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
