I would recommend replacing the capacitors smoothing the power supply because they are likely to be worn out and it will be hard to diagnose other problems. Also if they finally give up the could cause a fire!
I also noticed that the page i linked to in my previous post shows a diode in the video output which is supposed to improve working with modern tv's - might be worth a try.
