| Dear All,
I need help in fixing a problem on my Sony monitor. 10 minutes after turn on the set cuts out. After it cuts out if I switch off then immediately back on it runs for a few seconds then cuts out again. Sometimes the set stays on but with no colour. I have checked/ changed nearly all electros in the power supply and horizontal stages. I tried to accelerate the fault by hitting the power supply, horizontal and chroma stages with hot air but with the same result - switches off after 10 minutes. Likewise, I tried hitting the active components in the above stages with freeze spray hoping the set would spring back to life but no such luck. Any help would be greatly appreciated. Cheers & thanks, Don
