    Sharp LC-60LE660U

    TV is powering on fine either by remote or from the TV itself but once on it simply displays the Sharp logo but never proceeds beyond that. Once on no buttons work either (vol, channel, inputs, nothing) on the set itself or from the remote. The LED also just stays white, no flashing. I also am not able to power off the unit except by pulling the AC plug. This just started happening yesterday.

    No noises coming from the set either.

    I left the set unplugged all night, but no change. I did just locate the service manual but I am looking for a little guidance on where to possibly begin. I just another thread regarding an LG with a similar issue. It was suggested I check the main board or simply replace it. Would that apply here as well?

    I just bought the TV on 12/26 so I am contacting Sharp to see if this is still under warranty.

    I wonder if a button is jammed or otherwise faulty.

    Could be a corrupted EEPROM also

    Can you upload the service manual here so we can have a look at it?

      It ended up being a bad mainboard. I was able to get this serviced under Sharp's warranty.

        Do you have the Service Manual? Could you share it with us if you do?

          Sure do.

          I believe you are right about the corrupted EEPROM being the culprit.

            DeLonghi AC Remote only accepts 3V
            by cstout
            Hello all, I've been looking into this portable air conditioner's remote control and can't find what could be causing the problem - or possibly this remote is just terribly designed.

            The remote only works at exactly 3V - if I drop it any lower, using my bench power supply, to say, 2.9V then the remote will not flash the display and turn off. I don't have any AAA batteries that are exactly 1.5V each so I'm not sure if this remote is designed this way - to only use the freshest possible batteries, or if there's a failed component in the mix.

            I can't find any schematics...

            Toshiba 50lf711u20 fire tv remote not pairing
            by Mc_Millian
            Hello everyone,

            I was wondering if anyone could help my in pairing a remote with a Toshiba fire tv?
            The Tv model number is: 50lf711u20 Rev B.


            I've already replaced all the the circuit boards within the tv along with the I.R. sensor receiver.

            I've tried 3 different remotes which should be fully compatible with this TV.


            Oddly enough. A few if the buttons on all of the remotes actually work. Even without pairing...which makes no sense.

            The power button, along with the volume,back,select, and directional...

            HiSense 55A7500F won't obbey to remote after power on
            by edugimeno
            Hi! I have this TV set that does the following:
            1) I press the red power button on the remote
            2) The TV turns on normally
            3) After that it won't take any other command from the remote, neither power off, volume, channel, NOTHING
            4) We need to either pull the main cable or use the built in button at the bottom to select funcion OFF

            Then after it's off, it would again accept the TURN ON from the remote and same again

            BUT:
            -The remote does show the correct IR beam while observed thru a phone camera
            -The TV works fine while using the MiRemote...

            Pioneer VSX-522-K remote control not working???
            by tmhobadcap
            I have this receiver for at least 10 years. Usually, we just use the remote for turning on/off and adjusting the volume. Recently, the remote control started not able to turn the receiver on. Later, the volume also could not be adjusted by the remote control.

            At first, I thought that it was the usual problem which can be fixed by cleaning the contacts on the switches and the pcb. I opened the remote and clean it with alcohol. The remote did work again after that. But after one day, it did not work again. I opened it again and clean with alcohol and contact cleaner. Again it worked...

            Please help, where can I get a remote for my subwoofer?
            by rustinjust
            I’ve got a subwoofer that I’ve had for nearly 20 years, it did come with a basic remote which I’ve lost. It’s a generic make of subwoofer, I can’t see a brand sticker on it. It comes with 2 speakers.

            Question recently I’ve connected it up to my tv which has greatly improved the sound on my tv, however I’d like to be able to mute the subwoofer when ads come on or just mute it when the phone rings etc. I tried using a cheap all in one tv remote on the subwoofer and the volume button would only work to increase volume but not turn it down or mute it

            Is there...
