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
This is why its gone off when you moved set,you brought forward something that was going to happen anyhow.If you are practicable and can handle a soldering iron it may be possible for a DIY
Televisions are dangerous and the ht resevoir cap can hold its charge for many days after power down of the set.This information on an informative basis only.
