    Westighouse L2046NV dead Capxon

    Just got a Westinghouse L2046NV 20" LCD . Power light stays green when the LCD is connected to a VGA source, and one can see a dimmed picture, so the backlight has a problem. Opened the LCD see Pic 'LCDall': it has three boards, including a [1] processing board see pic 'GPU' [2] power and backlight board see pic 'PwrBacklight' [3] button board. On the power/backlight board, capacitor C204 [Capxon 220 micF 25VDC 105 degC] is bulging, see pic 'cap'. Failure of the cap has killed the fuse F200 located on the other side of the board very close to C204; this fuse is a very small surface mount fuse marked 'S' meaning I think 4A. Replacing C204 by a 330micF/25VDC/105degC I had and F200 by a much larger wired PicoFuse 4A solved the problem, and the LCD now works.

    The Westinghouse L2046NV LCD is also marked 'CHI MEI Model A201P2'.
    The Power/backlight board is also marked Delta DAC-19M005 DF Rev 00A.
    On the Power/backlight board, the other large caps are CE101 & CE109: Capxon 220micF 25VDC, CE103 and CE104: Capxon 1000micF 25 VDC, CE102 and ?: Taicon 2200 micF 10VDC. Hope this helps.
