Nokia 5220 send keypad not work


Your send keypad is not working because of the accumulated dusts and dirt beneath the keypad's surface. Here's what you've got to do:

1. Get your tool box and find something that can be used to open the case of your phone.

2. Using a diluted acetone, clean the contacts below your keypad. Surely, it will work after.

3. If nothing happens, contact a cellphone technician..

Tayebmy acer aspire over heats too much evev if I use it for a short time

The cooling openings and the air pathways over the internal radiators are filled with dirt so are blocked - use a vacuum to clean them. In the worst case the case of the laptop will have to be opened to remove stubborn dirt, a job for a repair shop.

Automatic lens cover won't open

Do you mean the shutters which protect the lens? If this is the case, are you able to carefully open them by hand? If so, there is a chance that a bit of dirt is preventing the shutters from opening. You might be able to get rid of the dirt by carefully sliding a bit of paper (I find yellow post-it notes perfect for this) in between the shutter and inside of the lens to shift the possible dirt. Also, you can try putting a minute drop of isopropyl alcohol (used in lens cleaning fluid) in between the shutters and the lens assembly so the possible dirt dissolves - then try to carefully open the shutters by hand. I don't recommend using any other alcohol/liquid for that.

Other than that, it's an absolute pain to get to the shutters to fix them properly on TZ3. Basically, the lens would need to be almost completely stripped-guide to do that would be beyond the scope of this site :)

Good luck,

Insignia Portable DVD Player does not play DVDs - says no Disc?

Unit needs to be returned for service under warranty. If not under warranty. You Must open the unit by removing all the screws on the bottom of the unit and use a small plastic pry bar to open the case around the space where the volume control is.slide the pry bar all around the case to open it.Becareful not to lose any of the switch cover that may fall off as you open the case. You must replace these covers exactly to operate the unit once reassembled. Check all rubber bumpers for hidden screws before trying to open the case. you must unlock the plastic locking mechanism all around the case. Then take apart the laser and motor assembly and disconnect all the wire straps and ribbon cables. Clean all these connectors with a contact cleaner by apply it to a cotton swab and cleaning. Try cleaning the laser with a cotton swab and Isopropyl alcohol. Put small amount of alcohol on swab and gently clean laser lens, Check transport for dirt and try cleaning the travel rails of the laser to remove dirt and grease and reapply a small amount of lithium grease to a swab . Lube the rails and ratching mechanism. Do all this with the utmost case, do not use to much grease or you will cause more problems..Use light gloves. do all the work with the cotton swabs. Check disc spindle and see if it is loose, if it is use a drop of super glue to to tighten the grip of the spindle to the motor shaft.Reassemble unit and put together in case put all screws back in unit and test unit on a level non vibrating surface. Use a clear disc from CD cases to check and see if laser is turning on and attempting to track normally. If this does not work attempt to polish laser head with soft foam material and non abrasive high gloss mirror or glass polish very carefully try to make the laser clear and shiney. Do not work to fast and do not push to hard on the laser or you will ruin the alignment.Slowly try to clear the lens of all discoloration.If all this fails try to buy a new laser mechanism from e-bay and replace your old one. Hope this helps you with your problem.

K750i radio icant use even im using a brand new headset how can i solve this problem

Hi. Had the same problem earlier. (I assume you use an original or compatible head set cable.) It turned out to be caused by corrosion/dirt on the contacts on the bottom on the phone. You should inspect it and you can use a small sharp object and gently scrape/rub the contact points until any dirt or miscoloration is removed. In the end these contacts will need to be replaced as they suffer from wear and tear as well as corrosion. New contacts are available as spare parts from many internet sources. If you need help to open the phone and change contacts, please add a separate request.

T30 Power up problem

The c-mos won't cause this. The power button is integrated into the keyboard, and uses the same connector as the keyboard to get power to the system. In most cases, the board with the power button (which is part of the keyboard) is worn out. Occassionally the keyboard connector will work loose or get a little corrosion or dirt and not make a good contact, check and clean the connection. If the connection is good, then I'm afraid you will need to replace the keyboard in order to cure the problem.

The sparker for the gas hob on my Baumatic B144SS is not working, yet the electricity is on and both the light and fan are working! Is there any way I can get it to work?? Cheers

You need to clean up burner and the sparker head from dirt which acts like isolator and prevent spark to jump. Burner must have metal to metal contact with the range casing in order to work. Grease, oil and burned liquids like milk act like isolators and prevent contact between burner and the casing (mass).

Just unplug the range from the wall, take off burner, scrub and wash off all the dirt from it and from its seat to the very metal. Dry it out completely and put back in place. Plug in the range and give it a try.

No Ignition

Dirt. Spilled oil, grease, milk etc. act as isolator and prevent contact between burner and casing (mass). You need to clean up burners, scrub all the dirt and make sure their seats are cleaned too (brass elements below burners).

Breaking thread

1. Make sure you are using the correct needle and thread for type of fabric and it is installed correctly. Make sure bobbin is threaded evenly. 2. Tread path - make sure the machine is correctly threaded. Then, with your finger, feel for burrs, nicks or roughness on any metal parts that contact the thread. Open the slide plate, remove the bobbin and inspect the bobbin case and hook. Remove the needle plate and examine the needle hole. Sand any rough areas with fine emery paper and blow away grit. If burrs or nicks remain on the needle, presser foot, needle plate or bobbin case, replace them with exact replacement parts, if they remain on the thread guides, take-up lever, bobbin hook or tension regulator, take the machine for professional service. 3. Loosen thread tension by adjusting tension dial. 4. Clean feed dog, bobbin case, and tension discs. Unplug the machine. Use a small, stiff brush to wipe dirt and lint off the machine head and the needle bar area. Raise the presser foot and the needle to the highest position, open slide plate and remove the bobbin and needle plate. brush away dirt and lint from the feed dogs and bobbin case and remove any tangled thread with your fingers. Use a soft cloth to clean between the tension disc on the tension regulator. 5. Also check tension on presser foot
