Model Technika LCD32-207
TV turns itself off by itself into standby mode, LED is normal colour (blue) and does not flash, no unusual clicking, buzzing or popping sounds.
I can turn the TV on again only for it turn off again, this may after 10 seconds or 20 mins.
When working, the picture appears normal
Is this likely to be a PSU failure or main board failure or both?
On inspection:
The PSU is 17PW20.1- 010507 possibly vestel
The main board is 17MB12-3 possibly vestel
(i say possibly as it does not have vestel printed on the board)
There does not appear to be damage to either board, the capacitors do not appear to be blown, no bulging or leaking and no obvious discolouration to any.
My knowledge of testing electronics is limited, i.e, no equipment other than a good soldering iron.
Anybody any thoughts?
