    Sharp LC-60LE820UN Dead

    I have 5vdc on PD connector pin#11. Jumped it to P'S - ON #10
    without any loads. The P.S. did not turn on. Voltage on main filter caps 170vdc. I bought another P.S. RUNTKA684WJQZ
    for 150 plus shipping. New P.S. does the exact same thing. It too will not come out of bypass with just power to board.What am I missing?

          I had a 60" sharp lc-60le810 that has a similar problem, The power LED would blink and the TV wouldn't power on. I replace the power supply and it still wouldn't power on. I replace the T-CON board, and that resolve the problem.

              I have no led blinks while in the shop. The P.S. will not jumper on. Even with the loads and Tcon connected. How can I jumper on only the p.s.? I tried with and without loads. I have jumped many P.S. In the past. But this one or the replacement does not turns on.
              The manuel does not tell how to jumper it out. The Trouble shooting section for the P.S. was incorrect with plug names even though
              it was the correct model number on the manual. AC detect pin on P.S. was 0vdc what should it read? Jumper it high or low or not at all?

                  Ecking767 . Do you recall what the P.S. connection to the Tcon was? Just power or power and signal wires? I guess the Tcon LVDS cable also had signal to main board to control the P.S.?

                      Dead Sharp Aquos LC-32LE430E
                      by borstar_micke
                      My 12y old daughters tv (that she got after her grandpa, has sentimental value to her) was just dead without stby light a couple of weeks ago.

                      Iยดve repaired a couple of computer monitors, classic blown capacitor replacements, a 55" Sammy led with t-connboard replacement and a 42" Panasonic edge led where I replaced the led-strip.

                      Not a master with the multimeter, which is cheap and 10-15year old btw...

                      So please make it basic...

                      To the issue at hand.

                      As stated, the tv is totally dead with no standby light....

                      Sharp lc32d42u seems dead
                      by metropical
                      plugged in after being off for quite some time. No OPC lights. Tried flashlight test for backlight check, nada.
                      Pulled the PS and checked all diodes including the 5w(?) D7908 that was the issue last time. All diodes check OK in circuit with DVM diode test.
                      No caps look unhappy. It is 17 years old. Was gonna fix and give to my brother.
                      But is there anything else to try or is it likely met its match.?...

                      Sharp LC-40FG2241KF dead
                      by Judderman69
                      Hello and greetings from the United Kingdom, I'm looking for some help in repairing my grand daughters 'dead' Sharp LC-40FG2241KF smart tv. I have replaced the following damaged parts on the main PCB (TP.MS6486.PB711) :- fuse FB1, switch mode chip UB101, MOSFET QB101,capacitor CB116, resistor RB106, RB148 and a track from UB101 pin 6 to QB102.

                      Unfortunately resistors RB105 and RB108 are also open circuit and because of their size (0201) I don't know their value. Could some kind soul please tell me or point me toward a schematic with a parts list, a very big ask but for this I would...

                      How can I be sure that my EC chip is dead?
                      by double_DD
                      Hi all,

                      As the title suggests, how can I be sure that my EC chip is really dead?

                      I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

                      Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...
