    Sharp LC-C5262U Won't turn on steady flashing green power LED

    I found out the steady flashing power led is a fault shutdown and can be reset by pressing the volume down and input buttons while plugging the power cord. The tv powers up with no backlight and then shuts down again.

    I found 2 voltages 10 volts gray wires and 42 volts white and beige wires that go from the power supply to both sets of inverters.

    And I think I have the necessary control voltages coming from the logic (main board) on the harness coming from the logic board I have a white wire with 3.2 volts and a gray wire with 3.1 volts.

    I searched here for other posts on this tv and found nothing related to my problem... Anybody got any Ideas I think I have a bad #2 inverter it has the master control circuit on it... I checked all the fuses on the inverters and all four are good.

      I have recently repaired a LC65D64U and it was the master inverter. Same symptom.

          Sharp LED TV flashing green 2x per second - LC-70LE735X, DPS-222BP, RUNTKA857WJQZ
          by beetle1303
          Sharp TV flashing green light 2x per second at constant rate. Various reset methods do not have any effect on it. Search here and found flashing green 2x per second indicate bad power supply, which I am quite certain now.

          I am seeking help with basic trouble shooting to find the short-circuit on the secondary side that I believe is the cause:

          The main PD connector:
          PD-1 (PNL12V) : 0.02V
          PD-2 (PNL12V) : 0.02V (fluctuating)
          PD-3 (SGRN) : 0V
          PD-4 (SGRN) : 0V
          PD-5 (UR13.2V) : 0.05V (fluctuating)
          PD-6 (UR13.2V) : 0.05V (fluctuating)...

          Sharp Aquos Lc-80LE757U flashing Sharp on screen when plugged in
          by sefoster
          I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp...

          Sharp LC-46D85U green power light & OPC flashing
          by kyho
          I have 46" Sharp TV LC-46D85U, recently it doesn't power on. It gives flashing one power light and OPC light together then flashing one on power light, then repeat the flashing pattern, I checked the forum and the error code for this pattern, it indicates the power supply board is faulty. I am not sure it is the power supply board or other boards. I measured the voltage on the PD connector, I have +2.99 DCV on pin 8 (AC_DET) and +5.01 DCV on pin 12 (BU5V), other pins and LB1, PL, LB2, LA connectors has 0 volt. I removed the power board and connected with BU 5V + 490 ohm resistor to pin 9...

          SHARP LC-60LE640X display flashing white noise patches and totally dropping out randomly
          by dmcabs
          Hey guys,

          I have a SHARP LC-60LE640X TV that has suddenly developed an intermittent fault of flashing white noise patches (appears like an Analog tuner off signal) and then totally dropping out.
          This model I believe is also known as LC-60LE600U or LC-60LE640U in other regions.

          FYI, a long time ago I was a component level repair tech for all consumer electronics and IT equipment.
          I'm a bit rusty but still have ability to dig right down.

          I measured all power supply lines and checked them for AC ripple voltage. Noting any lines that exceeded about...

          sharp lc-65ub30u plays but screen is flashing on and off
          by JunkmanJimbo
          Hey guys! It has been awhile since I've been on here. I hope everyone is doing well. I just picked up this Sharp lc-65ub30u. It plays but the screen is flashing on and off. Other than that i seems to be a great tv. Any ideas what the problem might be? I haven't pulled the back off yet. I thought I would get some opinions first. Thanks in advance for any help you can offer.
