Repair notes
Full repair description and observations |
|
|
|
|
|
1 |
Not much to say with
this fault because I was lucky to find the solution on the internet repair
database. It was stated that R1001 on the main PCB board must be replaced |
|
|
|
|
2 |
This was a 0.39Ohm
fusible resistor in the power Regulation circuit which gave a reading of 22kohm. I placed a
0.7Ohm resistor instead and the Video came back to life. |

R1001 (0.39Ohm) OPEN CIRCUIT |
Precautions, fouls and advises |
|
|
|
|
|
1 |
If the resistor was
placed with a higher value (eg 2 Ohms) it would get very hot and may burn
out. This is due Power Theorem of POWER = I2 R, larger R, More
power as heat is dissipated. |
