I have a plasma screen and a official remote, it was working no problem till one day It didnt and opened the battery cover to see the batterys had both leaked, why this happened I dont know but wiped the contacts gently with a mildly damp cloth.

Still nothing.

Left it a few days and still nothing so placed it on my radiator for a few hours and it worked but a few hours later the volume control didnt work.I left it for 2 days again and then tried putting it on the radiator for a bit again and volume control worked again(as well as every other button) then stopped working a few hours later.

I placed it on the radiator again and it worked for a short period.

Why is it that only the volume control button is affected?(that I know of) and why heating it sorts it temporarily.

Try putting it in the airing cupboard for 24 hours to dry it out completely if you have one that is. We did it with one that my son dropped into a drink and it works fine still.
#2
Open it up and wipe the mainboard down?
#3
It obviously doesn't like the cold :p

Have you got a sonic screwdriver that might help :whistling:
#4
As above, open it up, wash the main board off, let it dry completely (3 days in an airing cupboard to dry the water under the IC chips) and then try again.

Failing that, it may be fubar and an "all in one" type remote may be your answer!

Sounds like you may have either a dry soldering joint on the main board or the battery contacts are not very good. The heat may expand the joints/contacts enough to make a circuit. Check the battery contacts for corrosion. A gentle scrape with some emery cloth etc. may do the trick. Also, try twisting the casing slightly when it fails to work (like a Chinese burn) & press the buttons while flexed. May need someone to help you for this.

Well it had whiteish powder when the batterys leaked on the connections.

I now need to find a mini screwdriver since the screws are really small, any ideas on a cheap but strong one.

its possible the leakage is corrosive and has eaten thru a line, you can get conductive paint to repair the line if u can remember where the leakage made contact with the circuits.
as stated its prob only a small break and heating it up causes enough expansion to bridge the gap.
