DRc8335 says hello, wont eject tape, wont shut turn on or off with button on unit. I held down the button on the unit - no change. I unplugged the unit - no change. I put fresh batteries in the remote. No change.
Thanks to the help on this forum, I was able to fix my DRC8335 power supply. C226 was the problem, went to Radio Shack and found the 470uf 35V replacement. It came up and worked like a charm after soldering it in. (See the picture of the cap on the board). It was just slightly swollen when viewed from the top but when i removed it, the bottom was really distorted. Thanks to micro065 and Mike Powell
Hi, I had this exact same problem and got i bit lucky. All I did was took the cover off and removed the power supply board. Then I looked carefully at all of the components and found three bad capasitors. They were swelled. I replaced them and tested it to fully function. The caps I replaced were one 470uf 16v and the other two were 220uf 16v. I hope this will help you repair yours as well.

This problem is normally caused by a dvd player with a dirty lens that it cannot read or detect a dvd in the player. At the same time if this is a dvd/vcr combo a vcr that will not load or is stuck can cause the problem. These can be checked by taking the screws off the unit and taking a look at the position of the dvd laser lens or the vcr position to see if it is in the fully eject position. The part that holds the laser lens to read the dvds can be moved manually back and forth to dislodge it from a stuck position with the power off. Depending on how long it sat around it could just be stuck. You see when you first turn the power on to the unit initially or try to eject a dvd, it will cycle through and try to read a dvd even though there is not one there on power up. If that assembly that moves the lens to read the dvd cannot move, it will cycle off and turn itself off even though you try to reset it with the power button.
A transistor on the power supply can also cause this problem but without taking signal and voltage measurements it would be difficult to pinpoint the exact one. So try moving the laser lens assembly manually and then turn it back on. Let me know. Good luck.
The front panel display and buttons are completely nonfunctional and appear dead. The unit will do nothing more than display the following messages on the TV screen:
Interface error (and or) Interface error! Turn off the power
If a DVD or VHS tape was inserted prior to the error occurring, you won't be able to eject either from that point further. They'll remain stuck inside the unit until you've completed the repair detailed below.
