Television and Home Theater

does anyone know how to clean or is there any special cleaning
products for a Magnavox 51mp392h projection tv, it seems to have some
type of mesh covering on it, what i have been doing is taking a wet
cloth and cleaning each indviual spot. i have 3 small kids and as you
can imagine they are always get little drops of liquid on it. this has
been working but it takes a long time to clean each spot, i have
searched on the internet but no luck so far, any help you can offer
would be nice. also i seem to have one speaker blown, i have surround

I'm have no idea what my access code for my Quasar TV is and need to know how to reset the TV back to no access code.  I've been told that there is a way if you open the set and do something inside to reset the code to 0.  Can anyone help with a walk through to reset the access code??  Thanks.  Quasar 27 inch model #SP2723B

I dont think my tv is high def but what are those jacks for? Can they give me a better pic somehow?
