Hi Bruce,
At least with Vestel we get basic manuals, where we just have to try work out the thousands of variations for each 'Make' model, screen maker and screen size, all identified by numbers where Vestel gives no guide, as several different numbers may well work, or not.
Eeprom/Flash are a bit of a problem too - You might expect a maker to offer bins to download as they are troublesome - Naturally, they don't generally, especially where most needed on crap sets.
China isn't so easy, as not yet managed get a shematic for anything - Mind you, they do cheap bits on the Flea, postage paid. Try get something from America, and the postage is at least twice the price of the item which is odd as distance is comparable.
Can't complain about the UK - Chris.
