off topic a bit, but actually, yes. i've fixed my samsung 40" lcd tv twice over the past 5 years. both times caps in the power supply module went bad, so i replaced them the first time with identical caps, but they died again due to a flaw in the design of the circuit. so i replaced them with slightly higher rated caps.
but there still is truth to your "throw away" electronics idea. if the logic/codec board went bad in the tv, there's almost nothing you can due to repair it excet to buy a whole replacement pre-programmed board and chuck the original defective one (ok, properly dispose of it, lol). all of the chips are surface mounted on multilayer boards nowadays making it nearly impossible for a human to repair. believe me, i've tried with very little success. even wen using 20 power jeweler's loupes squeezed into my eyeballs.
andy, have you tried cleaning the contacts in the battery compartment? it might be that they've oxidised a bit over gime and the new batteries just can't deliver enough juice to make it work properly. just a thought to get back on topic.
