My wii will not read any of my games

You can try Nintendo's Wii lens cleaning kit. Also, some older Wii units have trouble with dual layer discs, which pack more info onto a disk (Super Smash Bros. Brawl and Metroid Prime use dual layer discs). If your Wii is having trouble reading a dual layer disc you can try Nintendo's Wii lens cleaning kit for that too.

If after cleaning its lens your Wii still can't read any disks then you'll want to contact Nintendo.

My projector turns off by itself after five minutes

Without any further information, I'd be inclined to attribute this to internal overheating - it's a very common issue with projectors and can usually be resolved by cleaning out some of the dust buildup - from areas like the air intake vents and the fibre filter layer (same sort of stuff as the filter in a cooker extractor hood).
This is actually a recommended monthly maintenance procedure, and, if kept relatively free from future dust buildup by doing a regular once over, you shouldn't experience this particular problem again.
If that doesn't help, please could you provide a little more detail - eg, any blinking lights on the projector, funny noises, error messages or codes evident at any point - and we can look at a few other possibilities...
Hope that helps!

REMEMBER though that electronics are very delicate and require careful handling - always wear an anti-static device when working with any electronics, and use only recommended cleaning methods, such as compressed air designed for use on electronics.

I have observed shadow at the upper right corner on the screen & how can I clean the inside part of ambilight from dust? Pls give me your recommendations.Thanks. (P.S:TV type philips 32pf9830/10)

You will have to take off the lcd panel itself and then take the panel apart.

There are multiple layers of plastic that illuminate with the ccfl bulbs.

Find the layer with the dust issue and clean with ammonia free cleaner.

You will need to have a dust free environment to do this, or it will only make the problem worse as you attempt to pull the plastic panels apart.

Goodluck...and please rate!

System fan is not working peroperly

If the system fan is not working properly, it may be due to dust inside the system. This will result in heating up of the system and the processor/ graphic unit may burn. So, IT IS STRONGLY RECOMMENDED TO GET THE PC CHECKED BY A PROFESSIONAL for service/ cleaning etc., to avoid any damage to the PC components.

Let me know if any further clarification/ assistance is required.

Good Luck!

I have a hp altec lansing laptop that is powering off and heating up, do you have recommendations?

Turn the computer off.
Disconnect the AC power.
Remove the battery.
Purchase a can of compressed-air.
Give your computer a "blow-job", shooting air into every vent that you can find, in order to remove all the dust.
A layer of dust is good insulation, thus causing your computer to heat-up, and self-protect by shutting down when "too-hot".

Also, check that the fan(s) are running -- too much dust can SEIZE the bearings on the fan, preventing it from spinning.

Don't be afraid to take the computer to a certified technician, for proper cleaning, if your attempt does not produce good results.

Please help on cleaning the mirrors

It is not recommended...not even for a service tech unless there is a definite need.

I think some people think that this affect the picture brightness and cleaning it will help. I can tell you that after 3000+ units(not an exageration) this does not need to be done and it is never the reason for the dim picture.

You are more likely to leave smudges then remove any. In some cases you may get spider webs or large pieces of dust inside but it is best to just vaccum or blow these specific items out. You can look inside 90% of these projection TVs and it is enough dust floating to look like a blizzard. You can not get rid of it and it really has no affect on the picture quality

Basically, I dont' recommend cleaning by anyone. If you do, just lightly dust or blow out with compressed are while vacumming the floating debris.

Plays cd's but lots of skipping going on. I tried cleaning with a CD player disc cleaner that I got today. That didn't help. None of the CD's skip in another machine. Thanks!!

When optical lens got dusty or thin layer of dust on lens, cd starts skipping, as you tried cleaning with lens cleaner cd but no result.
You need to open the unit and clean the lens with good quality cotton bud / swab with care.
Still no joy, replace optical lens.

Kenwood FreeTalk XL TK-3101 2-Way Radio

Hello hiyya1311,

I would really recommend against painting the radio. Paints may contain chemicals that can be harmful to electronics. Even if you could get the outer shell of the chassis completely removed and separated from the electronics components before painting (which is likely not a small undertaking), the paint can still emit fumes for a long time after drying and those fumes could potentially contain corosive chemicals.

As far as cleaning, most manufacturers recommend thay you simply wipe the outside of the unit off with a damp cloth when cleaning is needed. (NOTE: a damp cloth NOT a wet one.) Most radios are gasketed against dust so the inside of the radio should not require any cleaning. Should the grooves along the outside of radio require extra attention you can use a dry (or damp, if necessary) cotton swab. (Again, not a wet cotton swab.) Do not use cleanser or chemical cleaning products on the radio under any circumstances.

If you have experience in disassembling electronics devices and feel comfortable in your ability to take the unit apart and put it back together, instructions on doing so (including diagrams) are in the manufacturer's service manual which is available from Kenwood Communications. You can contact the manufacturer on their website at However this should rarely (if ever) be required for cleaning the unit and may void your warranty if you still under the warranty period of the radio.

Best regards,
"Go Ahead. Use Us."

Cleaning the inside of the front screen

It's not hard but is time consuming

You'll have to pull the front of the unit off to clean the inside. This includes taking out the screw that are open normally and there should be about 4 screws that are behind the bottom-back panel.

When you open the unit just be sure you get it clean the first time and don't leave any stray fingerprints on the glass. And don't touch the projection lens at all. Use compressed air to blow it off but I wouldn't recommend cleaning it unless it is just filthy and the canned air doesn't work for you.
