Hi Chris,
Great finding one of those! Very popular back then due to the compact size compared with contemporary sets. I used to have a 26″ 4402 version of this chassis for over 25 years. A very common failure here is the BF422 output transistor, usually marked TFK (Telefunken), Philips branded parts seem almost indestructible in this application. Dry joints are common on the 8003202 sub board. If not then a possible auto-cut off failure. Rich
