Hi guys,
This is my first "thecnical" post, I need to repair a Samsung Lt24a350 LED tv.
The TV turns on and if I press something on the remote the red led blinks.
This is the only thing that the TV does.
At the beginning I thought about a Power Supply failure, but when I Inspected the components there wasn't a single bad capacitor.
So I Inspected the mainboard, and at the beginning I thought it was fine, but after further inspection, I noticed a very very small hole in one of those small ics near the power connector. This is a similar visual defect to the one that afflicts plasma buffer boards where sometimes overvoltage causes the failure and overheating of one of the ics.
Anyway, without considering this visual defect (maybe it's only visual and the problem it's me that I see defects even in new things)
I would like to know if the fact that the display turns on when I disconnect the mainboard from the psu is sufficent to say that I need a new mainboard and the PSU is fine.
Thanks for your help!
Ps: I cannot test voltage outputs from the power connector that goes on the mainboard because I don't have a single clue where I need to put the pins of the multimeter...
