Just looking at this HS-U550 power supply. Does it have 2 plugs coming from the power supply marked PZ and PD. If so there is a resistor on that board R950, 2.2 ohm-1/4 watt. Check and see if it's open. -Ed BTW-the active components on the HS-U550 are Q902 to Q911, and IC900 which is LA6324N, does that sound right, comparing it to your board? ----- Original Message ----- From: "AL LEATHERMAN" <alleathe@xxxxxxxxxxxxx> To: <servicetalk@xxxxxxxxxxxxxxxx> Sent: Wednesday, October 03, 2001 9:51 AM Subject: ServiceTalk Fw: Mitsubishi HSU560 need power supply and display schematics > > Subject: Mitsubishi HSU560 need power supply and display schematics > > > > Mitsubishi HSU560 display and powersupply schematic needed. > > > > I got and installed new display and micro and display is still > dark,voltages > > look decent everywhere so I need notes.Any help appreciated and can > > reciprocate on TV service notes of which I have many. al > > > > May God give us strength > > Al's TV > > 224 Rt. 46 > > Mine Hill, NJ. 07803 > > 973-361-5796 > > alleathe@xxxxxxxxxxxxx > > > > NOTE: All messages posted to kdtv_servicetalk are subject to the mini-policy found > by sending email to majordomo@xxxxxxxxxxx with info kdtv_servicetalk in > the body of your message. > > Help make your TechAssist online repair tips database better!
