IIRC I saw a 19" version of this chassis when first starting out, it was 4 years old then and had a intermittent PS problem. I probably gave it back without much improvement. I was also unaware of how bad the solder joints could be.
I was baffled by a SMPS supply but I was not yet doing SS TV repairs for an income, then I had to learn...
