silverdale but I couldn't resist it. For probably around another tenner more your local repair shop would have fixed it by now. Prices are generally quoted based on screen size nowadays.
I would say the new breed of tv "engineers" probably do more board swapping than actual component level repairs. Tv's are far more complicated nowadays and the boards more densely populated, far more like computers with microscopic components. With ever impatient customers a board swap is usually preferable and the component level repair can be done later using the bench power supply.
It's a pity that those of us past and present in the trade have a reputation of overcharging. Youtube hasn't helped really where all the faults seem to be swollen caps. We loved those jobs as we made quick easy money, made up for the ones that you spent hours on, sometimes days and your profit was next to zero, but you had earned a customer. More often than not the repaired set also goes through a period of soak testing. Depending on the nature of the fault this could be a few hours or a few days, all in the price.
I think in my day that I had to wait 4 years after gaining parts 1+2 C&G before I could apply for part 3. During this time and after we seen the advent of the vcr, satellite, dvd recorders, home theatre, HD , 4k and loads of other stuff inbetween that I would remember if I wasn't on my 3rd generous glass of whisky. The learning never stops. There can't be too many other occupations that have seen so many changes in that timespan.
"A life beset with problems", I think @trevortron may remember where that phrase is from. By the way silverdale, my ramblings here aren't a dig at you mate.
