    Sharp LC32D44E-BK Stuck in standby mode

    Hiya got a sharp lc32d44e-bk from a friend stuck in standby mode, solid green led for 2-3 seconds then to red.

    I've done a visual inspection on all the caps on the power board, all seems ok.
    Checked all black diodes & Zener diodes, all seem fine except (D7134) DMM reading in both directions, .607 & .1116 probes reverse. Im sure thats a fault.

        Working fine for me. (That bit is my signature, attached to the first of each post on each page.)

        Try here for SM:

        But really, just follow the video I made and it'll be fixed in no time.

                The service manual i keep getting a error on the file.

                Yea ive tried a few times, keep getting the same result, solid green led, then the fuzzy picture like no antena connected, then blank screen led still solid green.

                That diode i mention you think its ok.

                  Sounds like 2 secs to black.
                  Will eventually accumulate enough errors to behave like in the video I posted.

                      Still no joy getting into service mode, tried quite a few times same result. get to the fuzzy screen picture then it goes blank, solid green led.

                        TV must be OFF (the standby LED must be DARK.) This is achieved either by pressing the soft on-off button or unplugging the TV.

                        Then hold VOL- and CH-.

                        Power up TV by pressing soft on or plugging in again.

                        Do you see a "K"?

                                If i hold down vol- & input --> and the on/off button it goes into service mode but it only lasts like 1 second then goes to a blank screen.

                                Turn right corner says EXT & AUTO, then halfway in the middle on the left of screen it says 'k' then some writing.

                                  K indicates you are in the first service mode, then you need to press the second combination to enter the full service menu. Refer to the manual -- I have forgotten the codes...

                                        Did a few recaps, still the same, RL701 doesnt make a proper relay click sound, sounds kinda flat.

                                        Tom66 think the buttons are ok, not stuck

                                          by Dvsr
                                          Hi. I need help from wiser guys. I am amateur in electronics and can't figure this out by myself.
                                          I bought faulty speakers, M-Audio AV40's. Other speaker has all the electronics in it and the other speaker is just passive one powered by the other speaker's amp. Original problem with the speakers was loud buzzing. I figured out that there is something wrong with the capacitors. I went ahead and replaced every electrolytic capacitor on the PCB. The caps are good quality and have the same values as the original ones.
                                          After replacing the caps I started testing out the speaker. It seemed...

                                          What Zener Diodes on a Linear Power Supply
                                          by caspian
                                          Dear members,

                                          I have a linear variable power supply with unknown brand name that I used for voltage injection.
                                          Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
                                          In addition, I discovered that its zener diodes are defective.
                                          I can replace the burned transistors.
                                          But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
                                          Therefore, I cannot replace the zener diodes.
                                          I do not want to test the zener diodes in a test circuit to discover their model or value.
                                          no schematics are available...

                                          I have an TV Led 4K Selecline 65s18 with mainboard T.MS3458.U801

                                          The TV is faulty with stuck in Standby RED LED. Can't power the TV.

                                          Before this problem , the TV stuck the picture with artefact , i unplug the AC cable and since the tv is stuck in standby .

                                          All voltage are OK on PSU and main board for regulator. I tried flash firmware 25Q64 with many dumps

                                          But the voltage on power button is 0.6V not 3.3V. When i press power button the voltage up to 0V. I tried to add 5V with Power Supply on 5V_STB and 3.3V on Power...

                                          Hello to all friends of the forum and well found, here I am asking for your help and sorry for my translated English.



                                          As per Hisense tv title LTDN50K220WSEU stuck in standby
                                          PSU rsag.820.5687 HLL 4855WF
                                          Main rsag 7.820.5842
                                          I enclose the psu diagram, after the first routine checks I find myself with a regular standby voltage of 3.3v blue light on steady when the power button is pressed nothing happens, psu disassembled and bench checked ... forced ignition by sending a signal 3 , 3v on the SW and PWM2 pins the psu turns on and delivers all the voltages...

                                          LG 32LB1R - stuck in standby mode
                                          by lego1234567
                                          Hi. I have the following problem with my TV. After connecting to mains, the standby led (red) turns on, but TV is not responding to remote control or buttons on TV. After some measurements, I found out that +5 V standby voltage is present, but I dont have ON/OFF signal coming in to turn PSU on. It stays at zero volts. After looking at the schematic of the mainboard, I should get ON/OFF signal coming in at the R1402 resistor, but it stays around +3,5 V. So I removed it and I was able to turn on TV with buttons on TV, but not with remote control.

                                          What could be the problem ? Thanks...
