when i stop using my marquee i always unplug it.
now when i plug it back in it always takes a minute or so before the pj responds to the remote (not wired).
is this normal or can this lead to bigger problems.

Interesting. Stupid question, but are you sure the batteries are OK in the remote? I know the pj does funky things when the batteries get low. Does it do the same thing when you have it in wired mode?

[dvh99]

no it isnt the batteries i always had this odd behaviour of the remote even with new batteries.
i use regular 1 1/2 volt batteries (duracell) and they are quality batteries.
in wired mote the pj fires up instantly as soon as i press the power button.

Hello

IR commands are detected in the IR sensor and acted upon by the control board. If the orange ready light is on then the projector should react. Next time you plug in, see if the remote is causing the diagnostic "C" led to flash on the rear panel.

will do that tim thanks, its flashing now but thats no surprise of course.
now i at least know what that c stands for on the clm.

i looked at the c led on the clm and indeed it doesnt flash.
after 1 minute it responds to the remote, flashes and the pj turns on.
i have the part that dragan mentioned in order and as soon as i have replaced that cap i will report back.
c145 on the clm.

the strangest thing happened.
i replaced 2 caps on the lvps rated 470uf 35v with same value but 50v near the output.
i plugged in the pj and the remote responded immediately.
i still will replace c145 on the clm but i didnt expect a cap change on the lvps could cause this or perhaps its just a fluke.

ok just plugged in the pj and it responds immediately when the power button on the remote is pressed.
can someone enlighten me how 2 cap changes on the lvps cause the remote to work properly.

[Tim in Phoenix]

[dvh99]

makes perfect sense.
makes me wonder how many more caps are dying on the lvps though.

[Sparky015]

I believe those caps are in the flyback section of the LVPS. Mike and others will tell you that updating the flyback section will do wonders for the pj. The other caps not so much, as the inductors handle any noise. The caps in the flyback section however, are critical for noise reduction and reliable voltage.

[dvh99]

now the remote works as it is supposed to, and the pj runs cooler as an added bonus.
have you replaced them too paul?

[Sparky015]

I have. I also added a 100uH inductor to the -85V line as well. Others up the value on some of the caps, but I left the values alone and just upped the voltage rating and quality in the flyback section.

[dvh99]

does that include those wima caps too?
if so i will put them in.



the 2 caps behind the wimas are the ones i replaced.

[Sparky015]

Yes, but not all the wimas are in the flyback converter section. I only replaced C68 and C62.

[dvh99]

paul do they need to be 100v or will 50 or 63v be sufficient.
the 100v is only us stock at farnell and i dont have another source.

dennis

[Sparky015]

Dennis, I would not go lower than 100V. I got all of my stuff from mouser.com. For the WIMAs, part number 505-MKS4.47/100/10P.

[dvh99]

thanks paul i will look into that.

i have found a source for those wimas 0.62 a piece and 100v rated.

[dvh99]

ok i thought i got rid of this problem but it is still there.
i replaced the tant dragan mentioned and it didnt help out.
the time it takes for the remote to respond depends on how long the pj has been unplugged.
ie: the pj is unplugged 12 or more hrs it takes approx 1 minute, when the pj has been unplugged <6hrs the pj responds at once.
if no one knows how to get rid of this problem its just bad luck cause the pj works flawless.
