Hi All,
I'm just starting to look at this 7 year old Samsung PS42C450B1W that, on first power up the picture is fine. Then, after a few minutes, the picture becomes distorted with highlight noise and solarization effects. This is present on tuned images along with USB sourced video files.
On brief inspection there was no obvious visible bad caps, etc.
Looking at threads related to solarization, many point to the T-Con board (named logic board in this service manual)
Before I dive in and start measuring voltages, are there any general pointers for this kind of fault?
I've found the service manual which was too large to upload so have provided a link here:

Many thanks
