if the laser were generating enough heat in the middle of the deck to burn you when you touched the outside the cd would melt
i would say that 75-80% of sales reps are just that sales reps and know very little about the product they sell
20 years of retail has proven that to me
i would say the heat your feeling is from the display or bulbs in the display

Pinhead why don't you ask someone who actually is an Alpine Tech, they will tell you that Alpine's lasers are set to run hotter. The fella I spoke with is the top dude @ Alpine in Western - Can.
From my personal experience, having owned Kenwood, Pioneer, Sony and Eclipse CD decks this Alpine warms up a CD more. Even if the internal amp is turned off and the deck runs in blackout mode, once the CD is ejected after being played for a good 1/2 Hour or so it's quite a bit warmer...This was exactly the topic of my discussion with my shop, and that day the Alpine guy happened to be there. My local shop is also the authorized Alpine service depot and the tech is of the same opinion.
Are you an authorized Alpine repair facility?

the heat is generated by the output chips and the display not the laser
i repair radio's for your information
laser have agc if you know what that is to regulate them

yo buddy
people who had cassette decks complained about this 15-20 years ago
are you saying this was generated by the cassette motor
20 years thats how long i've been doing it and thats what my life experience tells me
if you want to beleive them giver dude
next time you see the alpine rep ask him what was the cause of cassettes heating up
head to tape friction

Obviously you did not read my post all that carefully... You suggest output chips and display.. I specifically SAID RUN THE DECK IN BLACKOUT MODE (Just in case you don't understand that it means display OFF)
and secondly I said run it w/internal amp off (That means ONLY the preout section is on, and all amp sections are turned OFF, thus no significant amount of heat)...
So can you tell me how what YOU suggested applies to what I was discussing...since I already SPECIFICALLY precluded all the items you point to as the cause.
Enlighten me...

from what i understand blackout mode turns off the display so that still leaves the lamps behind the buttons on which is also a major source of heat
also turning off your output does it actually turn the output chip off or simply just not put an input signal to it
i would hedge my bet on turning off the input signal
if that is the case it will generate heat even at an idle
resistors, voltage regulators, power supplys ,transistors ,ic's, motor controller ic's
they also generate heat too
all contributing factors
i so not buy for a minute that the laser is heating up the faceplate
i think there are alot more contributing factors than what you think
i have serviced many a cd player and have yet to notice any heat radiating from the laser pickup
i have a alpine at the shop i can dissassemble and check for this laser heat
how long does it take to heat up the faceplate?

Ah my bad!! so we are talking about two slightly different things ... I am only adamant that Alpine HU's tend to run hotter than other CD-HU's I have owned or my friends and my brother currently owns ...and that is true even if it is in blackout mode, once I eject the CD it is hotter than hell.. (blackout mode does actually turn off the lamps btw).
In the normal mode my faceplate got HOT in the summer but once I activated the blackout mode it got only fairly warm, but still surprisingly so.
Now weather or not the amp idles w/o an input signal or if it is a true "turn off the amp switch", I don't know for sure ...so that could potentially be a source of heat even if the HU is running as a tuner.
Hope this helps...
