Default Re: Philips G23T210A

Hello,

Your set uses the first hybrid Philips UK designed dual standard TV chassis, usually referred to as "the 210 chassis".

It has an unreliable line output transformer (LOPT), that often failed when these sets were in everyday service.

Other common faults:

Short circuit boost HT reservoir capacitor (the original type was usually a blue or blue/white cased "Dubilier" mixed dielectric type). If my memory is correct, it is a 0.1uF 1000Vdc rated cylindrical component and vertically mounted.

Boost HT stabilisation circuit feedback resistors: 2 x 8.2MOhm 1Watt, "Erie"brand ceramic cased carbon composition types, which go high or open circuit (check these and the boost capacitor before condemning the LOPT!).

Open circuit mains dropper sections.

Your CRT, if the original, will almost certainly be a Mullard and is quite likely to be OK.

When you get the set working well, I'd be tempted to reduce the Boost HT setting to a value that just gives enough width, which may help to prolong the life of the LOPT.
