    I thought I would post this here as Ive tried the correct channels to no avail but many here know their onions <img src="smile.gif" border="0"> . My Dell monitor which has BNC and D-SUB connections recently has started to go wrong. Basically after about 2-5 minutes the picture goes from a nice picture to one which has the blue component missing, therefore white becomes yellow etc. The weird thing is if you switch off the monitor for a minute then back on again all the colours are fine then suddenly after say 30-200 seconds the blue gun goes off and white becomes yellow.

    Anyone have any ideas?, or perhaps recommend a local monitor repair place (Im near Birmingham,UK). I`ve had the casing off but there is a massive metal casing which I do not want to start dismantling let alone touch as I realise the many thousands of volts within!.

    Cheers

    Eliminate the obvious first...Does it do this via both sets of inputs? Have you tried different monitor cables?

    Could be a dry join that breaks connection once the monitor gets warm. Don't try to fix it yourself unless you are a qualified technician.

    Go to Yellow Pages or Micro Computer Mart and get some telephone numbers for local PC builders.

    Regards

    Yeah Ive tried it with the laptop/another laptop/main pc to no avail, its a very strange problem but it does sound like a dry joint like you say?. Ive also tried the BNC and D-SUB inputs and it does it on both.

    I noticed the other day that I had it plugged into my laptop and after 4 mins the blue gun turned off so that white was yellow so I unplugged the D-SUB connector from the laptop and shoved it back in and the blue came back for about 10 seconds then went again!?. It's still an unbelievable monitor (sony tube and very very faint line for such a large monitor) which seems a waste, hopefully it can be fixed <img src="smile.gif" border="0">
