The backlight keeps flashing and doesn't turn on. | 5v stable, 13v oscillating between 8v ~10v. defect in a smd rs802/10r resistor (close to the ics801cs) its value was altered, it measured more than 100r, thus changing the voltage from 15v on one side to less than 7v on the other, just change it for a 10r and the defect resolved! | EC | |

LED turns on, all voltages ok, has backlight, has audio, but no image | Tcon - 12v fp1 fuse open (I read in another topic that it would be 3a, I'm not sure), cause: capacitor cp47 (10uf ??v) shorted, I removed it and the 12v line went up. I took advantage and, prophylactically, I also replaced its twin cp46 (same specification and are in parallel) with a 22uf 25v electrolytic capacitor. apparently it is a common defect in this tcon, if you search you will find several qp2 transistors (power mosfet) charred because these capacitors short out and lead to the fet. I was lucky because my QP2 was good. good repairs! | 2000 | |

Does not turn on, no stand by light | (at power supply) oxidation on an icb801 track, dead power supply | I rebuilt the track and it started working again, remembering that normally the icb801 burns out..... so it's always a good idea to test | Saltech |
