Question about Pioneer SD-643HD5 64" Rear Projection Television

1 Answer

PIoneer SD-643HD5 My Pioneer DLP HDTV is not focusing the picture accurately. The problem in on the bottom half of the screen all the way across. The colors are not lining up correctly, creating a arc horizontally across the screen. The arcs are red and green. Is this problem easily serviced? Can a DIY handle this or do I need a service tech to come out? Any estimate on parts and service costs? Is the problem on a circuit board, etc? Thanks in advance for any help.

    The problem I am having is a distorted picture at the top of the screen and usually only for a second or two. It is intermittent and seems to work fine for the most part but when it does it i can rewind my dvr and see it in the same place at the same point in the show.

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-533HD5 53 in. Rear Projection HDTV Television - Need Manual ....


ManualsLib has the manual for the SD-533HD5 here: https://www.manualslib.com/manual/384249/Pioneer-Sd-643hd5.html . (The manual covers two models.) Once you modify the picture parameters (starting from STD, REF THEATER, GAME), these are stored as the User mode. If you press Menu when done changing the parameters, that input should maintain the User settings for the last setting until you change the Picture type. If you modified the parameters for STD and then return to that input and change the Picture to GAME, any modifications to the GAME picture parameters will become the new User Mode. See page 50 of the manual for the details: https://www.manualslib.com/manual/384249/Pioneer-Sd-643hd5.html?page=50#manual .

I hope this helps.

I have a 64 inch hdtv pioneer projection monitor sd-643hd5 and it won't fit into my basement. What can I do? Thank You In Advance, Bruce Morash


Ha Ha, I had the exact problem. I think mine is the same model of TV as well, I have a 64" Pioneer made in 2003. So my TV would hit the slanted ceiling above my stairs as I tried to move it down. I first took off the wheels of the TV and this helped but it was not quite enough. So since the bottom of the TV is flat with exception of the side boards and the front trim. I removed the front trim temporarily and cut off the side boards with a circular saw till even with the flat bottom. This gave me 2.5" more clearance which was enough to fit the TV downstairs. Hint if you scribe the cut line with a utility knife it will reduce chipping.

Convergence board cracked?


Once the board is cracked it is no longer repairable (even if it's a tiny crack that may not appear to interrupt any connections), and you would have to replace the complete board. Any attempt to repair or continue using a cracked board may cause more damage to the entire unit. You can find a replacement digital convergence board for a model # SD-643HD5 from this major Pioneer parts distributor at the following link:
