ECG traces are flat or missing
1

Solution:Panel mounting 6 pin ECG input connector on PCB 12032 (ident J2).Check continuity of ECG cable between side plate and PCB , If faulty replace.Details : Refer Cable SP1

Encoder not working
1

Solution:Check continuity of the encoder. If faulty resolder the wires or replace the encoderDetails : Refer Cable FP1 and Photo of monitor PCB's - Image 1

It turns ON in battery mode but not on Mains
1

Solution:Check the back panel fuse holders must be loose or the wrong fuse is inserted. (Fuse 5 amp slow blow 20mm, voltage rating - 250v)Details : NA

Keyboard not working
1

Solution:Check continuity between 6 pin relimate connector on PCB 12032 (ident J10) and 4 pin connector on the keyboardDetails : Refer Cable FP2 and Photo of monitor PCB's - Image 1

Monitor does not turn on
1

Solution:Check if fuse is inserted into the back panel (Fuse 5 amp slow blow 20mm, voltage rating - 250v)Details : NA

2

Solution:Check LED (ident D1) for indication if PCB is turning ON or not ; If the LED on the PCB is turning ON, then PCB is Ok. If the LED does not turn ON, then check continuity Check the input connector continuity (ident J1) on PCB 10004. If there is no conitniuty then replace the cableDetails : Refer Cable PS1 - Photo of monitor PCB's - Image 2

3

Solution:Check the PCB 10004 - The thermistor NTC 10ohm (ident NTC), Capacitor (ident MOV) could be burnt. Check and replaceDetails : Refer Photo of monitor PCB's -Image 2

4

Solution:Check the PCB 10004 - Regulator IC TOP 256 YN (ident U1) is shorted, check and replaceDetails : Refer Photo of monitor PCB's -Image 2
