I recently aquired a Vidikron TGS-XP, but only now came around to testing it. The following is the problem: When i power up there's a high-pitched "crackling" electrical sound, as one would expect to hear when there's a shortcircuit, or some electrical (high-voltage) device which is burning out. The first time i didn't quite catch it straight away so i let him light up, until i suddenly heard a few louder electrical "bangs" (sounding like a discharge). However, al this time i did have a perfect testgrid, utilizing all 3 colors, so it doesn't seem to affect my output (in the shortrun atleast, i killed power when i heard the louder electrical discharges). Does anyone knows of what could be causing this? my birthday's in 2 days and i would love to have the d*mn thing up&about then. Thanks. btw, i already opened her up, to see if i could find any physical signs of anything wrong, but couldn't find any, not physically, like burnmarks, nor optical, during boot/warm-up.
