    Re: Sharp Aquos Quattron LC-52LE810UN power cycle odd issue

    I laid the TV face down and the set has been on for over 2 hours this way with no power cycling. So I don't think its the backlights.

        Verify that all the board mounting screws are tightened, also try flexing the chassis to see if it will cause the problem to occur.

            Tightened all screws and checked all connections. As soon as I lift it upright it turned off within a minute. Unplug unit set TV face down and re plugged and it's working again.

                    Sharp Aquos LC-70C6400U Half Screen Dark
                    by scubacamper
                    I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
                    Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
                    when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display...

                    Sharp Aquos LC-40UG7252E LCD TV burn in?
                    by jonah1024
                    Hello!

                    I'm a few days old into this TV screens repair universe so please bear with me.

                    Recently, and all of a sudden my 40ā€ 4K Sharp Aquos LCD TV turned on with colors all smudged in some places on the screen that remain like that even without any kind of video source. I do have image but the colors are smudged/tinted/ washed out in patches as per defects. This to me looks similar to burn in but Iā€™m shore this is not an OLED.

                    - I did the classic unplug and hold power button to discharge the caps but it didn't help.
                    - I did a factory reset as well...

                    Sharp Aquos LC-60LE635E three blinks
                    by klassic
                    Hi community,

                    I will describe my problem with a TV in those short following terms to be the most precise :

                    What i have :
                    Sharp Aquos LC-60LE635E
                    power board DPS-162KP-1
                    main logic board QPWBXF733WJN2

                    symptoms :
                    white led light logo at startup,
                    after 2 minutes, blinking 3 times a row, repeating
                    no backlight (and apparently no picture, checked panel with flashlight)
                    no startup sound

                    powerboard investigations :

                    1-2 PNL : 0v
                    3-4 GND
                    5-6-7-8 UR : 13.15v

                    Sharp Aquos Quattron LC-52LE835X Totally Dead, no output voltages
                    by Joekhoe
                    Hello all, I'm Joekhoe, a newbie here and ask your masters permissions and solutions for the problem i'm facing at the present.

                    I am in the middle of working on a SHARP Smart TV model LC-52LE835X from my customer, which totally dead and there's no output voltages at all at the output pins even though i have replace some of the components the output voltages remain the same with 0 volt.

                    The replacement as follows:
                    1. IC7905 : TNY264PN (first found exploded)
                    2. Q7915 : BT169D (exploded too)
                    3. IC7901 : 1608B (controller ic)
                    4. IC7601 :...

                    Sharp Aquos LC-32LE600E, No 12v as no PNL_POW
                    by foxyUK
                    Can anyone help me diagnose this? Almost not worth bothering with, but it has 'sentimental value' for the owner. I'm no TV technician, but dabble a bit.
                    The TV has standby power but no reaction at all to switching on or reboot steps, No flashing lights or response to menu button. All voltages on the power board are correct apart from missing voltage on pin 12 of CN7003.
                    There is 13 v on U7053 but no 3v signal to switch it on. I don't really understand whether the 3v should come from U7401 in the standby control area, or (as suggested elsewhere) from the mainboard via pin 12....
