I’ve been unable to identify this 22in. hybrid colour set. The
fault is no raster, though the e.h.t. is present and correct.
The set is probably basically the same as the Decca 20
series chassis. As there is no screen illumination though the
e.h.t. is normal, check the c.r.t.’s first anode voltages (should
be over 400V) and its cathode voltages (should be under
200V). High cathode voltages would suggest a low -emission
PL802 luminance output valve or incorrect operation of this
