I still run a TV shop, But its not just TVs, its ALL electronics both commercial and consumer, including car audio repair and installation + remote starts and security.
Only way I can survive these days. TVs I can still do component level repair in alot of cases, as long as the processor isnt fried or something liek that. (which is pretty common nowadays). but I did notice as the years go by, each new "model year" with TVs have more and more proprietary ICs that cant be found unless its a pull from the black market in china.
Even have the equipment to do processor swaps if I have to, the BGA rework equip isnt cheap, and the process is very intricate, not quite to CRT rebuilding intricacy but its up there. The modern plasma TVs I change the QFP buffer ICs all the time on the Samsung and LG units. They all fail.
