C6022M / PATHEMARCONI [TV]

• Only snow on TV, ok in AV. Channel numbers are not lit.
• Occasionally does not start up. The light comes on, the channel too but only thermal noise. If you press several times it starts up.
• Saturation of picture with flyback line after a quarter of an hour.
• Transistor to replace line transformer MJ10011 (fit with Darlington). The BU500D do not function. (PATHEMARCONI - C6022M information)
• Very bright picture with flyback lines, G2 590V, chroma end collector voltage 195V.
• No sound, dark screen. U4 11V instead of 22V, no U6 8V?
• Picture cuts out for a very short time.
• Line amplitude too large. Picture and sound ok, 124V set.
• Vertical amplitude missing. Poor linearity with picture foldover in upper part.
• Picture foldover and lack of width. Picture only appears when line transformer is touched and picture is too white. All levels are at zero, white screen.
• At switch on brightness is very weak then slowly it gets stronger and there is a flyback raster fault, brightness pot cannot be adjusted.
• Black screen. No RGB on tube. Sound OK.
• No picture, no sound, perfect display when you change channels.
• No U1 voltage.
• No start up and intermittently remains in standby. Channel light stays on. No sound or picture. Does start up if you keep pressing with the RC or manually.
• No picture. Sound ok.
• No filament voltage and no EHT.
• At start up RC58, RL38 and power supply transistor B136D blow.
• No scanning. No U1 210V on CL30. Other voltages ok.
• Picture is like 2 superimposed diamonds. Power supply output 12 18V and U1 90V. Line BU base removed U1 160V. Lie transformer power supply output OK. When switching off TV vertical white bar. (C6022M tips)
• No excessive contrast. (C6022M tip from PATHEMARCONI)
• Raster frequency fails on some video planes.
• RC transmitter works at random.
• Picture remains in B/W. (C6022M tips)
