SOURCE: Humming sound, F9 and dead

Seems like I answered this, but maybe it's a different poster.

The 721 model code means it's an LG/Goldstar-made oven and F9 indicates a problem with the inverter or magnetron.

Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models.

I would suggest you contact Sears for service.

We're happy to help you and we'd appreciate your thoughtful rating of our answer.

SOURCE: stuck tape

The tape won't come out when resetting the drive. Error 6 is serious.
To get out the tape you must open the drive. But IBM has a discription online (and in the user manual) how you can do this.

SOURCE: Chassis Intruded, Fatal Error.....System Halted

I'm not familiar with that particulat model, but I'd guess the motherboard has a chassis switch connector, and senses the chassis be open. Could be because: - chassis open (close it), - switch defect (as a workaround, you could short-circuit it, or just unplug it - whichever solution works for you). As another workaround, you can probably disable this switch in BIOS.

SOURCE: Display powers of with power up of AVC

This is the problem with my LC-37HV4U. I plug in the AVC and the tv/monitor and I get both red power lights (not blinking) but no green lights, sound, or picture. I mean the tv screen stays black! It seems like their is no communication between the AVC and the monitor. I thought at least the screen would light up when the power light came on and being it has it's own power source. This tv is driving me nuts!! Can anyone please help?? Thank you.
