Hi folks

I bought this second hand Cinemonitor IIIA from a fellow op some time ago and regularly have issues with screen fogging, I think between the LCD panel and the protective glass screen. The intensity of the fogging seems to be dependant on ambient temp & humidity. It get worse the longer the monitor is on till a peak and then begins to dissipate till almost gone. Next day, it's the same all over again. Has anyone else had this problem and is it correctable?

Any and all advise appreciated.

Cheers
Norbert

Norbert,

Sounds like pain old condensation. Since it is out of warranty, have you taken it apart to see if there is a lot of trapped moisture inside the unit? Once inside you would be able to see if the protective glass is in a (failed) sealed unit or picking up and condensing the trapped moisture inside the unit.

The Transvideo people might offer some advice on clearing up the matter without charging you. Never know till you ask.

Thanks Andrew

I wasn't aware the protective glass was a sealed unit and that definitely sounds like the place for this condensation. It's something that I wouldn't have expected though here in the tropics where the temp doesn't go below about 10C or 12C in winter. This problem occurs at anytime of the year and any temp.

I think it's time to contact Transvideo for a solution.

Cheers
Norbert

Mayne throw it in a bowl of rice...and if that doesn't absorb the moisture you can season and eat it

Norbert,

I did not mean to infer that the protective glass was part of a sealed unit but only to check if that was the case. I was thinking that if it was part of a "blown" sealed casing that moisture could creep in and when the unit heated up the slow leak from a sealed unit would take quite a bit of time to evaporate the condensation... Hence, my suggestion.

If you are in a tropic environment then the temp may not have much to do with the ambient humidity which is probably high. If this is the case then again the condensation effect would be there most times. You fire up the unit, the condensation occurs as the unit heats up, the unit continues to heat up and slowly the condensation burns off.

If the unit is easy to take apart I would as it will give you a better sense of what has to be done to the unit to stop this from happening.
