Repair notes
Full repair description and observations |
|
|
|
1 |
When the TV was
flippedon the side and turned on, the raster with grains appeared |
|
|
2 |
On inspecting the
circuit board, cracks were found around the LOPT,and
the track sending the input pulses to the transformer was open. |
|
|
3 |
The track was closed
back with wire and the TV fault was fixed |
|
|
4 |
About one month later,
the client reported the same fault and it was noted that there was another
open track dur to cracks in the PCB. |
|
|
5 |
These open tracks were
closed again with soldering wire from end to end aver the crack. Other tracks
which were suspect of forming future tracks were treated similarly. 4 tracks
were closed, all of which were inputs / outputs of the LOPTX. |
