SHARP XG-MB55X-L PROYEKTOR

One afternoon coming someone who named ziko, bring a projector (LDP) brand: SHARP XG-MB55X model-L with a total death complaint, LED indicator does not turn on / standby (complaints that are generally well-liked the technicians). But not all devices so easy there ..1.Buka five bolts at the bottom, four on the corner, one middle2.Buka cover / casing top, visible board control panel.3.Buka four bolts on each corner block regulators from the top, lift a little and open a bolt metal casing which is located on the edge.4.Lepaskan all connections soket2 (4 for the blower, a power cord, a circuit protector, 1 output regulator)5.Angkat blocks / modules are hati2 control panel, because it deals directly with DSP blocks light.Of course the first time I checked was the power block Suplly; fuse his condition was still normal, signs that the TR / IC switching regulators are not short.Regulator block is divided into two, one for the series of main block / mainboard and block to supply the lamp.Once the regulator to observe it turns out his standby system does not work, the results of these measurements turned out regulator using IC STR-W6575 to its standby system.Although there are no visible components of a distinguished short / burnt, and its replacement IC STR Resistors supporters and several small elco (10/35-22/35) .. make this device can "start" again ..But wait, after all is installed neatly back, watch your power cord when the cord input voltage / PLN, how the flame condition led indicator led is Standb her? ..
  1.Bila still not lit, try to confirm his position circuit protector (located at the front next to a red light, when terprotek, simply press the small red button
 2.Bila red LED continues to blink / flicker, check that all socket installed properly, particularly the socket that led lamp (AN-XR20LP) and blocks of DSP (Digital Signal Processor)
  3. When the LED is green, back to red, check the circuit block lamp, block elco regulators.The rest you just wait for the display like this on your wall.

Note, you should never unplug the power cord when you turn off / shut down this LDP before red standby LED indicators, although the lamp was dead.
  If you have problems with its components, especially IC, it helps you contact the vendor, unless the lamp can be replaced (if forced) with Ben-Q brand.
