Entering service menu 17MB35-4 Toshiba/Hitachi main board.

[Dang]

Hi, I have the above board in a Toshiba 40BV700B which has a faulty DVB tuner meaning the Freeview service won't work, when this particular EXT is selected the Tv will also shut down in 30 seconds or so giving a constant blinking white light only reset when mains power is disconnected, indeed when turning the Tv off from any other EXT it will show the same symptoms. My question is this, I have a spare board that came from an Hitachi 32" Tv, it works in the Tv exactly the same way with the same menu system but does give the picture a distortion not too dissimilar to a Samsung LCD if the wrong screen size or type is used, so how do I enter the service menu and alter the screen type/size in the hope that it may work with the Toshiba? thanks, Andy.

Code for Hitachi is different usually.

Menu 4725 normally works for Vestel but try Menu 1461 for Hitachi

All codes entered on remote, press Menu followed by 4 digits in sequence quickly.

Thank you guys, just been into the Toshiba service menu and I see no option to change screen type or size so it's leaving little hope for the Hitachi version but of course yet to try, it could be different so fingers crossed.
