I greet you! This TV starts with the SHARP logo and so it stays, it doesn't "do" anything else. It is equipped with mainboard + power: TP.MS6486 PB710
                                         display: LQ315T3HC4U
                                 Serial No: B32CH5242EB27W38112070900233
I think it's a software problem, can we find something, possibly via usb? From what I found, nothing really "fits". Thanks!

The device is a sharp lc-40le540e and has the following defects: pressing the power key on the TVC lights blue LED on the front but there are no backlight, video and audio. In practice, in addition to the LED it does not light another, could be a problem of the power adapter? Thank you very much

Hi!
Tudnátok segíteni? Lenne ez a CCFL gép. Teljesen véletlenszerűén kikapcsol, majd vissza. Néha stby-bol magától bekapcsol. Lenne ezzel Valakinek tapasztalata, mi lehet? Kösz
