Thanks lads,

The thing that got me was that in the TV24 where I had this problem the EHT dropped but not the scan drive so the picture got bigger. Incidentally even after two years with the back over the radiator this isn't 100% cured it's now gone from about 20mins useable picture to about 2 hours but still fades out.

I was going to remove the LOPT anyway. The chassis is very rusty at the back so I was intending to clean this up and so will try out an oven trick on this. I just wanted to get the set as near to 100% reliable before I started removing bits.

I've tried all the R's that Steve P mentions above but not the low value caps. I'm still not sure how best to check these will a blast from a megger be a good test?
