The monitor will run for 4 hours, then goes black.
Symptoms: 1st 20 - 30mins. will have some jitters, then go away. 4 hrs. later with back cover on loosely, video will get jitters on bottom half of screen. Then display will freeze, with a black 3 to 4" high bar going all the way across the screen. Thirty seconds later screen will go black. Blue light on. Turning off then back on, it will have video again, but shortly go thru the same symptoms & go to black screen. There are no caps that look bad. There are no bad solder joints (checked with 2.75 pwr. loupe).
Does anyone have a suggestion as to where to start looking, hopefully for bad caps. I have an old Eico capacitance-comparitor bridge I can test them on.
Thank You for your help.
