id:= 014099
Blank raster, sound ok
The sandcastle pulse was distorted, surface mount diode D504 (DAN202) was leaky

id:= 014100
Colour intermittent
This was due to trimmer CT332, clean or replace (Pt no. 1-141-418-11), Now a 15pf Capacitor (Pt No. 1-102-851-91)
(Anonymous)

id:= 014101
Dark picture with green flaring and burning smell
Safety feed resistor R812 (1Kohm,1w) for the A1 supply was found to be burnt and D806 was leaky (used BY210/800 as replacement)

id:= 014102
Dead, no start up volts
Check R602 (270Kohms) under the chopper transformer

id:= 017340
Dead, no start up volts
Check R602 (270Kohms) under the chopper transformer, also check R614 (330R chip) under the chopper transformer
(Ga l Imre)

id:= 014103
EW bowing
C806 (47nF,250v) was split and faulty

id:= 014104
Int colour (adjusting CT332)
To adjust short pin 11 of IC371 to chassis then adjust CT332 for stationary picture or replace CT332 with 15pF capacitor

id:= 014105
Int flashing across picture
Check for dry joints on the l.o.p transformers earth pin and on the chopper heatsink also C802 and the line output transistors heatsink

id:= 014106
Int red
This was not due to Q706 or Q709 this time, the cause was the video processor chip IC302 (TDA3505-V1)

id:= 017151
Low contrast,although the OSG says not.
Check R816 (150K) for high resistance or O/C. Located near LOPT
(Anonymous)

id:= 014107
No picture, field collapse, sound ok
Check safety resistor R819 (0.47ohms,1/4w) for o/c

id:= 014108
No start up
Check R602 (270Kohms,1/2w) located under the chopper transformer for o/c

id:= 012109
Note on IC1001 replacement from PCA84C840P/016 when fitting new type with `a` suffix
Change R084 from 2.2K to 5.1K (1-216-066-00), R025 from 100K to 82K (1-216-093-00) and C006 from 100pF to 33pF (1-163-105-00), IC1001 (8-759-199-00)

id:= 016979
Picture and sound slowly fade away a few seconds after turn on, or no picture and low sound
Surface mount PNP transistor Q005 (DTA143TK) faulty, I did not have this device so I used a BCW61A

Picture and sound slowly fade away a few seconds after turn on, or no picture and low sound
Surface mount PNP transistor Q005 (DTA143TK) faulty, I did not have this device so I used a BCW61A. Also check C012 for Leaking Electrolyte through Pc board to Q005 position

id:= 014109
Picture goes to bright white raster intermittently
The sandcastle pulse at pin 10 of IC302 was distorted, D504 located by the l.o.p.t was leaky
