Change the fuse with (0.5 amp).
If it doesn't work try this:
From Samsung site:

1 Press MENU # 1 9 3 4 in sequence rapidly. The LCD panel should now display TECH.
2 Press MENU, and then press ENTER. The LCD panel will display Tech Mode.
3 Press the left arrow (4 Press ENTER. The operator panel will display [YES].
5 Press ENTER. The toner warning message should be gone.
6 To exit TECH MODE, press MENU # 1 9 3 4 in rapid succession, as if you were dialing a phone number. The operator panel should no longer display TECH.

Then you don't need to use fuse after that.....

A6 turbocharged. Whyu does it smoke when it covers a 120km per hour?

I am going to say 'blown turbo'. As I understand it, they needs replacing every few years. They are susceptible to heat and incredible revolutions. They have to be lubricated, the seals go, and you get smoke.

Sony 6060F blown fuse

there is a standard procedure for proper replacement of blown fuse: CRT TVs: unplug degaussing coil, replace blown fuse with 2amp fuse and turn on the set. If it works, reconnect degaussing coil, replace the fuse with correct value(5-8) amp, depends on model(see fuse note next to holder). Enjoy the show! If in a process of replacing the blown fuse with 2amp w/o degaussing coil it blows again, forget about the next step. Set need repair. It could be an easy one, replacing 1 or 2 shorted diodes or bridge rectifier, but could be real piece of work if the power supply got "fried". If your knowledge won't go further, than fuse replacement, I'd recommend local TV repair shop.
good luck,

Headlight are not working

Sounds like a blown fuse. Have you checked the fuse? The owner's manual should have a diagram of the fuse box showing what each fuse is for. Locate the fuse box...usually under the dash board next to the driver's side door. Pull the fuse for the headlights and shine a flashlight on the clear plastic part of fuse. If the wire in the plastic part is broken, then the fuse is blown. Many gas stations carry fuses, make sure to replace it with a fuse having the same amp rating. Fuse should have the amp rating written on it (5, 10, 15 amp etc.).

Good luck

My Whirlpool microwave is not heating. The light, turntable and fan is working. What is my next step? model MH2175SXQ-0

HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))
