    Sharp LL-172C-B

    I had not seen one of these on this Forum so I thought I would post about it.
    When I opened it up nothing appeared out of order. It had NCC KY Caps and also had C5707 transistors. It did not have any of the FU9024 fets like the BenQ/Dell 17" monitors have. This is also a 17" monitor.

    On the Power/Inverter Board I replaced all of the KY caps mostly with KY's except for one Nichicon. I also took readings with my DMM on the 5707's two of them were out of whack on their readings compared to the other two. I replaced the two that looked bad. and put it back together. When I started it up it went 2 seconds to black. So I took it back apart and replaced the remaining two 5707's and fired it back up. This time it came straight to life and has been running now for about 30 minutes. Nowhere on the board did it say who made the board. It has a number 715L-1063-2-SH which I googled with no luck. One other interesting thing is that it has two small rectangular fuses near the AC connector that are listed as T2A 250v Double Pole Neutral Fuses. The last thing I did was to resolder the pins on the inverter transformers in case that was what made the 5707's short, similar to the BenQ's problems. Another item to note about this monitor is that it has a power switch on the front and one on the back of the monitor.

    I took pictures of the top and bottom of the Power/Inverter Board also.

    Sorry stated the wrong name for the caps. The originals were United Chemicon's as were most of the replacements.

      This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

      I picked this TV out of a trash pile. When I plug it in I can hear the relay on the power supply “click” almost immediately, and then 7 seconds later there is another “click” and the power/OPC LEDs start to flash: two pulses on the power LED, one on the OPC LED. I didn't notice any sign of life from the backlight, but more on that below.....

      The service manual () says this is a “DET_10V error: UR10V or A9V is not applied”, but after checking several voltages I believe the power unit is tripping off due to an overload as soon as the backlight tries to come on; this kills...
