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

Open Question

I have a Pioneer HDTV Projection Monitor SD-643HD5 TV. It has worked perfectly for 7 or 8 years. Today, in the middle of watching a DVD, the screen turned bright blue but the sound continued to play. Same blue screen with another DVD as well as for the Wii and Playstation. What happened and can it be fixed? If it can be fixed, what is the approximate cost for the part(s) and the labor? Thanks for your input.

SOURCE: Color Problem on SD-643HD5 (Green is not working)

I had a similar problem with my Green CRT. Fixed it by carefully touching up some solder connections.

1) Locate the Green CRT Driver Board mounted on the bottom of the Green CRT.
2) Locate the two large heatsinks on the driver board. Each has a transistor attached to it.
3) Carefully touchup the solder connections on each transistor. I added some additional solder to help reflow the solder onto the pad of the circuit board. It's a bit tricky because the solder has to fill a large gap between the small leads of the transistor and large holes in the circuit board.

SOURCE: HDTV Projection monitor will not power on

Problem solved. With the set plugged in(but in stand by mode) I took the back off. There are two LED on the left board that, if on, identify a problem. The D111 LED was on. I traced it to a blown fuse-FU303 which is the center fuse, about the middle of the center circuit board. I tried replacing the fuse 3 times, after each, it would blow. Another chat section on your site suggested using a 5a(up from 4a) fuse; that fixed the problem. The set works great. Your IC fix worked fine, although getting the boards out  was quite a chore. Your link to the instructions on how to R/R the IC chips was invaluable, and the set of instructions on the process was very complete and well done. Thanks for all of your help!

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.

Pioneer SD-643HD5 HD set up


Yes a simple cable will do it. Look for a converter designed to display a computer vga on an HDMI jack. I have one, and would expect it to work in reverse. My cable has a male VGA like a computer monitor cable.
