Set has power, but will not power up. Power LED flashes repeatedly. I was told that the problem was the power supply from the person who gave it to me. I tried searching for a replacement PB, but they are no longer available.

Re: set has power, but fails to turn on
Your going to need a schematic diagram and some troubleshooting skills here or a quilifyed repair person. This set has several power supply problems as well as sweep dirived power problems. The biggest problem is the STR (I dont remember the other #'s)(ie- STR#####) regulator IC It is alway the first thing that goes bad in these chassis. Now do not get a general replacement as it will blow out as soon as you turn on the set. I've been through this and a half a dozen regulators till I relized that the replacement ics do not have one last digit on the ic that the original did have!! and that one last digit made the ic completely differant. Another common problem here would be The Two filter capacitors off the sweep derived 15 or 18 volt lines Good luck to ya.

that is custom system like mine a DIY build
and custom unstated case., bought as new case only I bet of vast.
and if built wrong it fails.
the LED is where the POWER on LED wired wrong is it.
the Power on led does flash wired correctly for sleep mode.
if wired wrong is now the HDD activity LED, and should flash
x58 is good chip set, pure intel it is
usb3 chip NEC needs good driver so watch out there.
goes to pins 2 and 4 only on the header. page 30 in linked manual
if is wired correctly the led is called MSG
MSG/PWR (Message/Power/Sleep LED, Yellow/Purple):
Connects to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the sys-On is in S1 sleep state. The LED is off when the system is in S3/S4 sleep Blinking state or powered off (S5)
so the manual told you blinking is S1 power state ACPI.
bad LED (power button)
loose wires at mobo end of that or at power switch.
mobo bad, here, rare as hens teeth if user did not jumper DC power to this LED pin and blow the driver transistor up. guesses wild does that.
BIOS controls (you set it) soft power off , instant off or off. mode.
no case told some are dead wrong here, some cases , use a 2 way LED for power, and is 2 LED wired in parallel and reversed
to get 2 colors . and fails on simple mobo. not using bipolar controls to LED. NO CASE told so NO JOY , 10,000 cases made or more that the same but generic cases do work if is that, not OEM cases..
Tv is going into fault protection mode at startup. When set turns on relay clicks then turns off with NO OSD-On screen Display and a blinking fault LED. This in indicitive of blown UF capacitors on the PSB-Power Supply Board. On an opened set the PSB is located in the center. You want to look for 2 or more UF Caps on the PSB. A bad Cap will be completely poped or bulding at the top (X) which shold be flat. THe X-main Board is to your right the YSUS Main is to your left
It is very likely that one of the convergence correction chips has gone south on you (either that or a capacitor). What you want to look for is a swollen capacitor , or a burnt resistor near the two large heatsinks on the signal/convergence PCB. The flashing LED is an indication that the power supply has detected a fault, your mission is to determine what that might be. another thing to check out at the fuses on the power supply PCB (these have labels like FXXX were XXX is a number). If you find an open fuse, that will help determine where to look for the fault.
