Some news
The other day a friend comes to see the tv, since he works with electronic from 30 years.
We dismount the tv and do some measurements with the tester.
We just found that:
-The lamp button is working correctly, because if i don't push it i got green light flashing on the lamp led.
-Both fan spins and works correctly when we switch on the tv.
-On the power board we have 390v on the output, so it should be ok.
-On output of the lamp power board we got nothing.....
We remove lamp and put the tester into the the power board output and we got no volts, nothing...
Don't know if there's something prevent this, but just seems to produce no voltage on the output....
All the time the tv have the power led red.
Then i switch on the tv using the remote or using the key on the front panel, and the power led become orange and start flashing, then after some times just come back to red.
When this happen, both fans stop spinning.....
All seems to be working perfectly fine, so i just don't know what's going on.....
