Monitor V1428NI --H.O.T. running too hot and shorting
This is a 14 inch monitor V1428NI that i fixed replacing the hot
(BU2520DF) for a 2SC5296 but it gets too hot. Well it was hot with the BU2520DF too. And it won't accept 800x600 and 1024x768 . Only 640x468. It used to accept the three of them. I have replaced the horizontal driver (IRF620) with no improvement. I have checked caps and resistors near the hot and driver. All test ok. I notice there is a blackened coil, but it is not open. Any ideas. Thanks. |
