Hi,
This could be a possible worn laser pick-up problem.

Hi,
I have same DD 5.1 tiny "bursts" problem with satellite HD channel. It is probably problem with Crystal DSP (German site): http://forum.digitalfernsehen.de/forum/showthread.php?t=89328&page=3
"Denon bietet Lösung für EX-Flag-Problem bei den Modellen AVR-1602 und AVR-1802 an
07.08.2002(cr)
Dass die Denon AV-Receiver AVR-1802 und AVR-1602 die mit einem DD 5.1EX-Flag versehenen Tonspur von "Atlantis" und dem "Herrn der Ringe"nicht abspielen können, ist ein spezifisches Problem von einerbestimmten Revision des in diesen Geräten verbauten Crystal DSPs.Dieser Chip wird u.a auch in einigen Kenwood- und Onkyo-Modelleneingesetzt.Da es von diesem Crystal Chip unterschiedliche verbauteRevisionen gibt, von denen aber nur eine bestimmte betroffen ist,werden die beiden Filme auf dem größten Teil der verkauften AV-Receiverohne Schwierigkeiten laufen.
Denon bietet nun für alle betroffenen Kunden, die ihr Gerät beimdeutschen autorisierten Fachhandel erworben haben, eine kostenloseModifikation an. Das Gerät muss beim entsprechenden Fachhändlerabgegeben werden mit dem Hinweis auf das Herr-der-Ringe- bzw.Atlantis-Problem.
Momentan steht nur eine begrenzte Anzahl an DSPs zur Verfügung - Denonhofft, dass kurzfristig ein größeres Kontingent eintrifft.
Denon bittet daher die Kunden freundlich um Verständnis, dass nichtalle betroffenen Geräte auf einmal und sofort umgerüstet werden können."

Hi...
I would say "belt" 1st too.

Belt is there.

Hello,
It is very likely that during the transportation, a loose contact could have been created. Now whatever be the case, since it does not turn on at all, the Laptop will have to be opened and the motherboard checked. Get a good technician to check the board for you and with the appropriate tools, it is very likely that your problem will be solved.
All the best.

Belts for decks are universal, there are plenty of places on the web selling them. Parts for a Denon from 25 years ago is another matter. However I think you might need only the belts, as the longer tapes speed problems suggest that it's the load that's causing the belts to struggle. All you need to do is measure the diameter of any belts for replacement. HOWEVER before you remove them make a note, or photographer, how and where they fit.
Use Servisiol Video 40 to clean the rollers and head.
Testimonial: "Thanks for your reply. Hopefully it has set me on the right track. (Was worried capstans or motors were the problem). "
I had exactly the same problem with my Denon DCD-910. Fixing it is easy, but it took me a while to find out;
In the power supply +10V and -10V unstabilized lines (in front of the 7805 and 7905 +5V and -5V regulators on the heatsink),
there are 2 ICP-N15 devices (IC protectors: very fast acting electronic fuses 0.6A). PCB component print is IC502 and IC503 if I remenber well. They tend to deteriorate over time and break, or a current peak could have made them tripping.
The +10V/-10V (+13/-13V really) is used for driving the loading/spindle/sliding motors and focus/tracking coils ONLY. +/-5V was still OK, that's why you can still see the display.
They have a TO92 transistor housing, but only 2 leads. ICP-N15 are hard to find; You could also use ICP-F15, but these have a different housing.
You could order the original ICP-N15 at utsource.net
An alternative could be to mount 2 polyswitches (also called multifuse), a PTC type current limiting and recoverable circuit breaker, like Bourns MF-R065, rated 0.65 A
I replaced them with 2 radial 800mA PCB solder mount fuses (1$/pc), and everything works fine again. Yet another piece of excellent equipment not to be thrown away ;-)
You have to unmount the PCB from the CD player housing (about 8 screws and disconnect all 10 connectors) to be able to replace the fuses.
While it is disassembled, check for broken solderings, especially on high power devices ( like voltage regulators mounted on heatsink or power transistors)
I hope it works for you too.
