OK. I am having a problem with my Sanyo losing horizontal hold after being on for 1-2 hours. It starts with just a small droop or jitter on the left side of the screen eventually ending up in loss of the hold.

I got out the cooling spray and once it loses hold, if i spray around the HH section of the monitor I get a stable picture again. A minute or two later as it heats back up, I lose it again.

What type of components would be suseptable in this area. It's hard to direct the spray on one component in that area as they are all so tight. If I hit in the area of R463, HHold pot, and a few others I get this reaction. The only thing I can tell you is that R463 does not show the cold like the others. It seems to flash off like it's really hot. I checked it out against my other EZ and the resistance in circuit seems to be the same.

Any thoughts.
