Question about Dell E173FP 17" LCD Flat Panel Monitor
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

This oven is programmed with a self diagnostic failure code system which help for troubleshooting -H97 and as described above "mica piece and burnt smell" sound like Inverter Power Supply. DO NOT try to repair or re-adjust preset volume on the board. It is very dangerous to repair or adjust without sufficient test equipment because this circuit handles very high voltage and very high current Operating a misaligned inverter circuit is dangerous due to the Very HIGH voltage and current that is produced by this board.
Defective board must be replaced with new one -INVERTER POWER SUPPLY.

DO NOT try to REPAIR this Inverter Power Supply (U) and also DO NOT RE-ADJUST PRESET VOLUME on the board. It is very dangerous to repair or adjust without sufficient test equipment because this circuit handles very high voltage and very large current. Off alignment or inverter board operation is dangerous. Operating a misaligned inverter circuit is dangerous due to the very high voltage and current that is produced by this board. Defective boards must be replaced with a new one.
