Question about Mitsubishi WT-46809 46" Rear Projection Television
Its a board error in the tv.as the solderings on the board are got loose .after sometime when the board gets heated up the solderings become firm and the tv works. now why after getting warm the solderings becomes firm ,this is because.actually there is spray that is applied on the board to keep the solderings firm and tight.after some time in many tv the spray gets dried up and solderings becomes loose.after getting warm the spray melts a bit and due to that it again gets the firmness which the soldering joints require. so just get your whole board dry soldered at any local tv shop.they have this machine for dry soldering.in that they will apply the spary again. this will help. please do rate the solution.thank you for using fixya.keep updated.thanks.

Is the TV sited by a speaker or other magnetic device. Magnets cause this sort of problem. Can easily be shown by putting a magnetised screwdriver close to the front of the screen.
Is this an old tv? When I worked in the trade I used to regularly gave to take a degaussing machine out to the home and run this over the set.
