Either its a bad green CRT or a driver issue to it. In any case not for the novice to fix.

SOURCE: Pioneer sd-643hd5 rear projection 64" tv has green geometry grid problems

Wow, that first link is perfection! I'm worried though. The photo on that link shows the base grid green pattern looking VERY geometrically even with only the red and blue lines off. On my set, the green base grid geometry is off/wavy. Are the IC's the correct fix?

SOURCE: pioneer sd-643hd5 fuse issue

The fuses may not be your problem--I have fixed several of these---The large power board is on the right side as you look from the back?

Lots of these sets develop bad solder connections on that board--several sites on the internet offer to have you remove and send them the board to resolder--this set used lead free solder and after some years has problems--a few I have opened had clearly broken solder joints--I usually in this case remove the board(mark all the many plugs and make a diagram) and solder almost all of it by hand----usually fixes this kind of trouble.

I do this here for free so if this information was helpful give me a vote here....I am here to help people.

If you have any questions or need advice reply to this posting here.

Pioneer 65" TV Model # SD-643HD5 won't power up.


I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?
