NOTE: I am about to rain many, many questions upon all of my cherished forum members. This will start today and end... well it probably won't end anytime soon.

This is due to a complete dissassembly of my projector to replace c-elements. My quesitons will not cease with this one thread, trust me.


QUESTION: I figure it's probably okay but want to make sure here. Will I run into any problems by using compressed air to dust off my tubes (they are out of the projector)?


I used some alcohol and a paper towel to wipe dust off some of the wiring. Afterwards, I wondered if the alcohol will eventually dry out the wires. Maybe I shouldn't do this.


I already removed all circuit boards and dusted them with compressed air and toothbrushed them with denatured alcohol. Don't see any problems with that. I did the same with most connectors.


I also opened up the LVPS and HVPS and did the same there, where possible. The HVPS is an odd little cage of electronics.


I pulled off all plastic earlier this month and took it out on the lawn and washed it down with a 95/5 mixture of water and simple green degreaser. Really cleaned up that tan. I wiped down the metal innard panels with a damp cloth. Everything air dried.


I decided against modifying any circuit boards or anything else, due to wanting to make sure the projector works after my first dissasembly. I don't want to wonder if it was the anamorphic mod that killed my projector. So I'll get it all together and make sure she works, then slowly mod things.


I would have liked to wrap the HV lines in something to keep them from arcing. But, I didn't see any suitable material in time.


THANKS ALL!

Here is the Item No. 2480851180 (e Bay)


This is where I got mine from, worked a treat.

Whats the benefit of using that material to cover the HV lines?

Rob,


I'm just making a guess here but from the looks of it.... It makes your projector seem a little like a "high end" car stereo installation.

Chris Stephens was the one that did this mod.


His reason was-

This completely removes all sizzle and crackle. it also stops 90% of the tiny arcs to the metal during use which lead to memory corruption and all sorts of weirdness.




Hope this helps


Cheers

Steve,


Does it remove all the sizzle and crackle? If it does,. it may be more usefull then just decoration after all.

Brian,


I have completed only the HV wire out of the HVPS so far,

and YES it did reduce the noise of the crackle at startup.


I will have the rest of the tubes covered tonight,

So I will report back with the difference.


Cheers

Steve

Brian,


While it "may" remove some high resistance arcs to ground on startup, it can't remove the "sizzle or "hissing" (for lack of better words) sound of HV coming up since the sound is actually like static electricity, which can't be eliminated.


The oem Panasonic tubes come with ONE and sometimes even TWO layers of clear plastic tubing over the HV wires. When VDC rebuilds the tubes, they send them back with NO clear plastic tubing over the red HV wires, which is usually the cause of most HV leaks that occur. They also, for some unknown reason, find it necessary to slop all that silicone over the HV cap.

I guess now people will think you're "plugging along" with worn out HV wires.

Thanks! Ordered one 10' roll! Cheap too.


So, any comments on the cleaning?


Thanks guys!

I use isopropyl alcohol, I don't like using denatured alcohol because it's TOO strong, although it depends on what you're using it for. I use silicone spray on metal parts and wiipe them down.

When its low humidity I use a new soft bristle paint brush followed by low static canned air. Doug

To me, it's ALWAYS low humidity where you are.

Thanks again, Steve. Here are my results using color-coded tape. I bought a package of red/blue/green/yellow/black from Radio Shack for $4.00. Not the best quality tape in the world, but it should work okay:
