    ILO TV32HD solving Mainboard Problem?

    Have a very used ILO 32HD model TV.

    Problems, started that the set would not turn on the PS_A line.
    Per info on the web, I jumped the PS_A line and set turned on.
    For 3 hours ran fine, I was able to use the remote to function everything, BUT noticed that when using remote, the picture would flash with every key press.
    The top panel buttons however, no good. I see they are using a resistor per key method, for those functions.

    After 3 hours use, now the set is stuck in Composite and 1/2 volume.
    No remote response anymore.
    Turned off for a day, tried again, still no response.
    So I have looked up online to discover mainboard on these all need to be replaced with an updated version that has a heat sink on the processor, etc.
    I have searched and cannot find anyone having a new or used part. And of course it would be pointless to buy a used one since they all fail the same way.

    What I am wondering is if anyone has come across a solution of replacing part(s) of the mainboard to make the remote and top keys to function again.
    It would not seem as though the processor could fail to run although some seem to say the data lines are at fault. It would be cool if someone knew what the factory did to change the failed boards into the revised ones.
    Sadly now I have a nice paperweight or a monitor that is stuck in composite mode. I want to just switch it over to DVI mode to use as a computer monitor, although it may not be the best choice. (Set is only 720P) but it seems to show in the spec to be ok as a computer monitor.
    Then all I would need is a DVI cable to hook it up.
    Could care less about using the speakers, or anything else.

    Does anyone know how to erase the locked up condition long enough to get the remote to respond? I had it in DVI mode during those 3 hours of use, and it seems to remember to stay in the last mode even when unplugged.

    So if anyone has any more insight on this, appreciate.

    I am having the same issue with a ILO-26HD tv. The only way I've had any luck is to do a complete discharge (Hold the power button down for 30 seconds with it unplugged). As far as the board goes or a work around so far I have found nothing. Best of luck I will keep you posted on my progress as well.

      The main boards for ilo have been updated but are hard to find. mostly the 26".

      I was able to find a couple that were new and updated. I have repaired one that I found had a bad 3.3v regulator.

      There are several on these main boards. ( regulators) These will fail low like 2.7 volts.

        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...

        What is a normal composite signal range for a C64?
        by Scruit
        Hello all,


        Working on my first C64 / Breadbin / 250407. Purchased as non-working. Getting black screen.


        More detail below, but for those that want to get right to the question.... Here are a few waveforms comparing the Pin15 output on the VIC chip (luma/sync) to the pin 4 on the AV socket (composite signal).

        https://imgur.com/gallery/PpqcqPY


        My question is: Is the composite waveform range of 0.1v-1v too low for a c64?



        More detail:


        Symptoms are that that I get...

        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...

        un60j620dafxza - Samsung No Display Problem
        by stylishconsultant
        Hi All,

        Need help.

        I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

        So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
        problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
        might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....

        Dell Latitude 7420 - Touchscreen not working since Mainboard replacement
        by Mirenia
        Hi everyone,

        I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
        I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…

        In Windows Device Manager, I just see an I2C HID Device with error code 10. Sporadically, the touchscreen is recognized correctly for just a few seconds, but I haven’t been able to determine under which circumstances this happens.

        The touchscreen also doesn’t work in UEFI/BIOS, although it’s enabled...
