SONY AVD K800P receiver plays CD's Not DVD

[DIODE]

I have a Sony AVD K800P CD/DVD receiver/player that will play CD's (after reading for extended period) but will not play DVD, costs $14 at community Thrift store so no big deal, but would like to get the DVD to play. I've tried the CD "cleaning disk" that seem to make no diference at all , have not opened it yet, it's semi-permentelt mounted under a shelf (I know ....I should have completely tested before installing) I've seen online references to laser power adjustments that seemd to fix for others with similar problems. Anyone seen this before and got it fixed?

Open it up and clean the lens directly with a soft paper cloth.

Had the same problem with a DVD player. (Played CDs fine but with a DVD would show "Loading" for about a minute then "No Disc".)

"Lens cleaning" CDs and DVDs don't seem to work for me. Didn't work on the DVD player, but after cleaning the lens directly it worked.

If cleaning the lens is unsuccessful you could always try giving the laser assembly a bath in isopropanol alcohol. Fill a jar up with enough to cover it and agitate it for a while.

Failing that, as a last resort, you could look on the laser assembly for a couple of pots, grab your multimeter, set it to 20K ohms, check them both, mark it down, then adjust them individually counter clockwise (reading descending) increasing the voltage in small increments testing a DVD after each increment till hopefully it reads. If it does, hopefully in the process you will have worked out which is for CDs and which is for DVDs and you can set the other back to it's original reading. If you go to low you will kill the laser though. I did say it was a last resort...

Had a look around for a replacement laser for this. I think it's a DBU-1 A-4713-410A.

Found one on the fleabay although you would need to confirm it is the same part.

Thank you tom66/py3m4n- I will try the cleaning first and the pot adjust as /if required, Yes I think I tracked the assembly to a DBU-1 about a week ago, could't recall the PN# thanks, but right now it's back to the 5 volt problem with I-INC IF281D monitor (separate thread - main TV in the house, oh the pressure!!)
