    Yet another Q for the boys,

    I done two new systems with Philips 170b TFT's. One of them is intermittently going green, the screen that is? Picture is mainly good but every now and again the screen starts to turn green, still see the picture no problem, just with a green tint. Hardware problem? I reloaded all the drivers etc and checked the cabling and it wouldnt fault the whole time I was there, I never reseated the graphics card (should have) but a few days later it's happening again. The sytem is 40miles away so it's a pain in the a*s Any recommendations before I box it up and ship it back?

    I found something:
    Click on the link below and scroll down quite a ways until you come to the paragraph posted above. Looks like a hardware issue but you'll need to send it out to a specialist for repair unless you are an expert. Anyone else trying to open up a monitor and reaching inside is asking for a one-way trip to electrocution alley.

    Just to pick up on this small point - the above advice would be relevant to CRTs but surely not TFT's, as this case is referring to ?

    Or am I wrong again ? :oops:

    Hi dudes,

    I am in possesion of the monitor in question and have had it running for almost a week now with no problems. I am convinced the monitor power cable is to blame. Its the only thing I never swapped. It is currently powering a loan CRT no problem but I cant see that the monitor is faulty after a week of testing with no errors. Garaunteed I drive 35 miles only to find out its back to old tricks 5mins after I'm out the door :dry .

    Um
    TFTs, especially the larger ones, still pull heavy on the power and have a fair few capacitors and shite in them, your still likely to get a good shock if you touch the wrong part
    infact id estimate a 20" TFT pulls as much power as a CRT, i wouldnt say i bought them for thier power efficiancy improvement ;)

    Also remember your gonna get a pretty hot backlight to scald yourself on, so just as many things to watch out for with these buggers! :)

    Sorry that must have been misleading,

    It's just a straight kettle style cable, I aint fiddling with no monitors insides. Reseating the graphics card and replacing cable, thats it.

    Cheers :p

    One more thing you might want to look at (hope you do not mind getting advice from someone who is not one of the "boys") is the pins in the connector. If a pin is bent or recessed it could cause a tint shift. This was more common with CRTs but it could still happen. :hhhmmm
