SHARP 70GS-61S Ch.:GA-10
Sziasztok! Fent nevezett készülék került hozzám javításra, előzményét nem ismerem "csak nem jó" címszóval adták ide. Találtam pár kiszáradt elkót, zárlatos sorvég tranzisztort és mellette egy zárlatos FET-et. Ezeket kicseréltem de bekapcsoláskor csak "nyüszítő" hang jön a sorvég felől és a tranyó melegszik. Trafót próbáltam a teszterrel de meg se nyikkan (ha jól kötöttem?!). Gondolom ez okozhat ilyen hibát.?
Sharp LC-40LE341S no picture
Hi, mainboard Vestel 17MB70-5P. When turned on this TV, backlights comes on, I can hear the sound but no picture, just blue screen. When turned off to standby, the red and green led stays blinking. With oscilloscope I can see some signals in mainboard in cn26 to t-con. Previously on this TV have had some problems with the memory chip. Failure became suddenly, TV did not start anymore. Can anyone give advice on this problem? Kossi

led tv SHARP LC-32HG5242E locked on logo
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!
