Plasma screen went blank.

Based on the symptoms you have described, it is possible that there is an electrical issue with your Bruno VPL-3100 lift. The buzzing sound and burning smell could indicate a short circuit or malfunctioning component within the electrical panel.
Since you have already tried unplugging the lift for a week and the problem persists, I would recommend that you stop using the lift and seek the assistance of a qualified technician or electrician to diagnose and repair the issue. It is important to address electrical issues promptly to prevent any potential safety hazards or further damage to the lift.
It is also worth noting that attempting to repair or modify the lift yourself could be dangerous and may void any warranty or service agreements that you have in place. Therefore, it is best to leave the repairs to a professional who has the necessary expertise and equipment to safely diagnose and fix the issue.

leave it unplugged
take it in for repair and get a proper diagnosis done
normally anything other than a fuse is not worth repairing

most likely failure of module in the tv, most likely fuse, capacitor, something burn up, find the air vents smell the area your smelling something burn up smell, if you have every smell electronic stuff burning up you will understand what i mean you will never forget that smell.

where there is smoke, pops something went---find another shop that knows what they are doing---never plug in a set that smoked!

No that is a very dangerous situation. What is sounds like is you had a short that blew apart but not completely damaging the wires. You should unplug, and open it if its out of warranty and inspect the wires. If the wires are partially burned it can heat up and cause an electrical fire.

get real bright flashlight shin close to the screen in dark roomand try to push the menu button if its the bulb you'll see some picture with flash light shining that shows your backlight is out

Any set is repairable. It is the question of the cost and the availability of replacement parts.
It sounds like a component overheated and blew. Most likely there will be collateral damage where other components will also be damaged.
The failure could be in the power supply, or in any of the main drive circuits in the set.
You will have to call for a service estimate. In considering the age of this set, my preference would be to go out and get a descent LCD or Plasma set. The picture quality and performance of these new sets are far superior to the one you have!
