Just had this one in can run for day's & no problems,but on hot day's will go to stand-by & not come back on until it's called down.I had a good look at the power board to start with & all the joints that are riveted looked dry/cracked joints,so carried out a re-flow. Set ran for almost a week continuously
without fault,but today shut down twice with flickering st-by light.After heating & cooling board down,came down to a group of three opto couplers in the middle of p.s.u.the bottom one of the three being the guilty party. I have to say,this set is a Quattron display set,the picture quality produced is one of the best I've ever seen,fantastic detail,very natural colours.
