    Sharp lc-52d62u won't power on 5v sub is present

    I had a sharp with a bad psu, i replaced the whole PSU we a new one from shopjimmy
    part# 184wjqz

    i now have all my voltages now correct except pin3 and pin4 that give me 0.24V and should be 12V

    I hear tv clicking and trying to turn on now, but no pic or sound.

    any idea why i am not getting the 12V out of the new PSU now on Pin3 and 4

      We need good clear hi-res pictures of YOUR boards so we can see what we are dealing with, that will be a starting point.
      EDIT: you already have another thread for the same TV!

          here are the best images i could upload through photo bucket.

          PSU board is new.
          voltages as follows

          13.41V
          13.41V
          0V
          0V
          9.9V
          9.9V
          0v
          0v
          0.24v should be 12V
          0.24V should be 12V
          0V
          6V

                  Sharp LC52D62U Pwr Supply RDENCA184WJQZ
                  by rviani
                  Anyone know the correct output voltage of this board to the inverters? This board is used in many 42" to 62" Sharp Aquos (2005 - 2010 era) TVs. Also known as ZEBRALC605-4001CC.

                  SOMEONE must have this data - help gratefully appreciated.

                  Thanks in advance.

                  After many years of service this unit now refuses to turn on and gives a once per second continuous blinking power indicator. Service manual indicates this is a "lamp failure".

                  If I force the power on with Channel down and volume up buttons I measure correct power supply voltages at the main board. The Power supply to the inverters (connector LA) measure 10V and 47.3V which I don't have a value for from the manual but appears should be 24V. LB connector which I guess are control voltages to inverter measure 3.3V, 3.1V, 0V, and 0V at contacts 1, 2, 3, and 4 respectivly....

                  I have a Mb LA-A993P REV 1.0 computer, I am guiding myself with these two shared boards. ;
                  there are some ICs that are not the same, in this case those of the PU1501 (JD4TB) and PUH1 (NF4SA) images.
                  n, please identify.

                  330mA of consumption after 8 seconds turns off. +3VALW AND +5VALW present, EC_RSMRST# , LID_SW# , EC_ON# , ACIN# present.
                  ​

                  SUSP# NOT PRESENT, which would be this the problem does not turn on sub-sources Any leakage?

                  I also notice that in the PLH2 coil that belongs to +1.05VS according to the drawings I am not sure,

                  Hello,

                  I have a Lenovo MB LC40CM 19863-1 when press button is pushed the keyboard backlight turns on and off twice and the power button light keeps blinking and the fans spins for a few seconds and stops then again spins and stops (Three times) then laptop turns off. no image on screen. sometime when you leave it for few days it will turn on and work but once you restart it won't turn on.

                  Tried to reball RAM 1,2,3,4
                  Checked all voltages on big coils all present except 1V_VCCGT is not present I get 0V on this rail. is this voltage should be present once power button...

                  Driving a Sharp TCON/panel with a universal main board
                  by advant
                  This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                  I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...
