Hope your having a good day
Their is no available info for this model because of its age I would guess its CRT format with a line output transformer (if its rear projection it will still have a line output transformer)
Philips Manavox are favourites for cold joints (or dry joints)if you feel up to it you need to get the chassis out with the line output transformer on,the chances are their will be dry joints on the transformer or therabouts,possibly around the powerpack too
