Question about Denon AVR-3300 Receiver

1 Answer

Horizontal Purple bars appear on monitor

Once the Denon amp has been for 15-30 mins horizontal purple bars appear on the screen. These tend to oscilate up or down slowly. Sometimes they stop, other times just continue throughout the whole usage. Sometimes a light tap on the amp stops them, temporarily.I was wondering if it was to do with heat build up on the heat sink from a incorrectly operating fan?

Heat sinks get hot....thats what they are there for. Are you using the composite, S, or Component video ?

Composite or S :.....The board for these is right next to the heatsink. It may very well be that the heatsink has "cooked" the solder on this board, and now it is intermittant. More likely is that there is a suspect solder connection that was there from the factory from day 1. I would get a shop to look at it, unless you are very handy with a screwdriver and a low wattage soldering iron. Be forewarned, the connectors for these boards that connect them to the main circuit board on the bottom of the unit are SUPER FLAKY and taking it apart might cause more problems.

Component Video:...THe component video is on the power side of the unit and if very easily accessable. Again, IF you are handy with a soldering iron and a screwdriver, I would unplug the unit, remove the top cover and re-solder the component video board, starting with the connections on the RCA jacks where the component cables plug in. If you dont feel comfortable doing that, leave it to a shop...in any casem the bill should be minimal......good luck....rob
