A newer TWP4210 has an LG screen and will only work with a TWP4210 tuner (VMB1110 Rev. 1) - connection to a TWP4205 tuner results in both screen and tuner box being able to 'turn on (green light)' BUT NOT AT THE SAME TIME ! - If tuner turns on screen goes into standby and vice-versa
Earlier Techwood screens were Samsung made and the tuner box was LG and now the whole set-up is exactly the same as the Goodmans GTV42P2.
Vestel bought out Techwood which were a Currys own brand and you may get some information on the TWP4210 from Currys website.If not try Vestels italy site but the language is obviously italian,a bummer but Yahoo may translate some sites so you never know.
