Well I say ‘old’ but these days anything over five years old seems to be considered ‘past it’. Well this seven or eight year old TV was brought into me completely dead, no standby light, nothing. This was expected to be terminal by its owner but was infact just a very small capacitor in the power supply. No, it wasn’t bulging as most of the youview and Google ‘experts’ would have you believe, actually in the last few weeks I’ve replaced several capacitors that show no sign of failure, the only way to diagnose them being with the use of a specialist meter. It was a good result for the owner of the Philips though, as it meant they didn’t have to shell out for a new TV!
Today threw up a curious one in Old Cleeve, she is a customer of mine who uses two aerials to achieve the full freeview lineup, one on Eastbury Hill, Carhampton, and one on Wenvoe in South Wales to pick up the extra channels not available from Carhampton. The reception from the Welsh aerial was completely missing, meaning her favourite channel, ITV3, was missing. Up on the roof there was not a sniff from Wenvoe, I suspected the aerial although it wasn’t very old, but before replacing it I thought I would just walk 20 feet to my left across the roof where there was another chimney. To my surprise the signal from Wenvoe romped in here. There was the exact view to the horizon from both chimneys, there were no obstacles to obstruct the signal on the first chimney, so a bit of a mystery. I ended up moving both aerials to the other chimney where perfect reception was to be had!
I shouldn’t be too surprised, back in September I was installing a Wenvoe aerial in Williton, which should be dead easy, but the signal I was getting was awful…until I moved the aerial 18 inches to the right – the other side of the chimney, where the reception was perfect. Thank god for signal strength meters!
All that was left today was to deliver the Samsung TV that had a solarised picture back to it’s owner in Dunster. I was shocked when he told me he had taken it to the local TV retailer in Minehead ( once again mentioning no names ) only to be told it could not be repaired, shows how much they know!
Below is a capacitor that looks in very good condition, but is actually very faulty, faulty enough to stop a TV power supply from operating. So my question is…when these so called experts on Google tell you to look for faulty capacitors what are you going to look for?
