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

2 Answers

Tv works and then shuts off after being on for various amounts of time

I have a 64" Pioneer SD-643HD5 rear projection tv. When the tv is on for any good amount of time it will turn itself off and attempt to restart itself automatically. Once in a while it will come back on, but usually i turn off the power and wait. is it a heat problem or more that that?

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..

Red shadows on my 64 inch Pioner HD TV


It is probably in need of an alignment, which is pretty typical for rear-projection TVs. Try calling a TV technician.

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.

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.
