Hi. Our 1 1/2 year old Sharp KB6524PS Microwave Drawer: While cooking oatmeal, at start of cycle, the microwave started arcing, then smoking. Shut off at 15 seconds. Microwave-safe china used.

I expect the arcing came from the waveguide cover or aerial cover having either a crack or carbonised food particles on it.
A new cover may affect a cure if the magnetron is not damaged.

My Sharp Aquos tv turns off after couple of seconds.

First I don't think you should be doing this with the back off and then laying the tv on the electrics .it should be on stand with some input signal e.g. Sat, DVD or tuner .if it still issues the signal warning then it might mean the phase of input signal is not matching the tv which I believe is 100 hz .does the tv standby light come on after the tv drops?does it flash a certain number of times?if not then the power supply is likely to be causing the problem.the shortening length of time points to a capacitor that has or is failing on one the control panels.they hold a residual charge so when you switch on second third time it cuts out quicker.there is usually visually evidence such as burn marks, brown staining or the capacitor it's self has swollen split.
sometimes you can resolder dry joint with heat gun or iron but best to source replacement capacitor of the correct values and make sure you reseat the correct polarity so check the original before swapping out.And never do anything with the power connected to the mains or your signal light will come on for the last time.look on YouTube for tutorials on this.

Goes emiediatly from dos to blue screen over and over

You have one of possibly two issues. Issue one bad memory or memory slot. Test each memory chip individually, one will probably cause the computer to blue screen and that will be the bad chip. If they all cause a blue screen, test in a different slot. If this works then you have a bad slot, if not the try issue two.

Issue two, your OS has become corrupted. Do a fresh install of windows (wipe everything out), then reload your drivers and all software.

hope this helps

I need help with setting the color on my sharp aquos LC-40LE820UN. My reds are brown,my greens are brown, and my blues are very bright.

If the colors do not change when pressing the av mode button and selecting dynamic fixed then there is either a problem with the component cables you are using (most likely), a problem with your set top box or a problem with the television. I recommend trying another set of cables first. Try all of the television's inputs and connect different devices to it.

Just purchased this and need to know what the blue wire is, the brown is and the green is. (from China of course). 'Thanks, RSTAR CT520 PLasma cutter/tig/arc welder 3 in one

If those are the power input, then the green is the grounding wire (safety ground).

If the unit is 220/240 volt, then the blue AND brown are the hot wires.
Neutral would not be used in this case.

If the unit is 120 volt, then the blue is the hot and the brown is the neutral, but your unit probably requires the 240 volt. Check the owners manual and label on the unit.

LC-32SB24U LCD HDTV... Brand new, just out of box. Turn on, goes to language menu for about 1 second max,too fast to adjust, then screen goes black and little green led power light starts to blink. And...

Good Day, texxastam;

Do this:

3. Plug in the TV. (the TV will turn itself on).
4. A blue "K" should now be showing on the TV screen, release the buttons.
5. Press and release the VOLUME DOWN & CHANNEL DOWN buttons simultaneously on the TV. (A blue service menu will appear on the screen).
6. Using the remote, press the DOWN SELECT button once. (The highlighted line should read INDUSTRY INT (+CAUSE) OFF
7. Using the remote, press VOLUME UP once (OFF changes to ON).
8. Press ENTER. After a few seconds the screen turns green and shows - Industry INIT success - at the top of the screen.
9. Unplug the AC cord for 10 seconds then plug back in.

Good Luck, big IRISH.

PS; I did not make this up... it's from SHARP> again good may have to do this several times....too...get the timming down.
