    Try testing before you bin the Zener diode and a replacement need to be 1/2w 30v. just getting a little hot does not make it faulty, most run a little hot .the more likely fault is with CB804 33uf 50v cap that this diode is in running with, overloading the Zener

        Guys, you are amazing !!!
        So far so good !
        Diode and cap (CB804) has been changed and all voltages looks perfect now, 18V, 12V, Va.
        Need to keep the TV on for an hour or two to be 100% sure.
        I'll let you know later.
        Thanks a lot !!!

            Please dont say you got the parts from maplins,if you did it wont last the day out. The caps need to be low ESR for them to work correctly and that Zener needs to be min 1/2w

                Lenovo s145-15api work fine after bios flash for some time, like a few restarts or power cycles.

                Hi! I have a Lenovo s145-15api Ryzen 5 3500u, he need a bios reflash, i made that (tried with ch341a and ezp2023+). I tried a lot of dumps, and all do the same, so i think is a hardware problem. So after reflash, laptop work fine a short time, after some restart or power on/off, the laptop have again same symptoms, need a new bios. Do it again and again and same result. What are u think is the problem?

                Gaming Laptop Zephyrus S17 TFT not detected every time !
                by titomno2
                Hi guys,
                I post my problem here because I think it could be a capacitor related issue (Asus support on this particular subject is non-existing).
                So the computer is a Zephyrus-S17-GX735LXS-26T and the strange behavior is seen.
                On cold start most of the time the internal screen is detected and a picture it works fine until shutdown, sleep or deep sleep.
                Then the screen won't work for a long period of time.
                If I wait 1 or 2 hours it work again most of the time.
                When it doesn't work the batterie indicator blink 3 times white stop and the same schematic is repeated...

                Macbook Pro 8.2 2015 kernel task 100% and very very slow
                by smic717394
                Hi,

                I need a bit of help. I have a Macbook pro end 2011 8.2. I bought it of a customer cheap because it has a bulged battery. I replaced the battery and upgraded the ram 2x8GB total 16GB, and replaced the HDD with a SSD. What happens with this laptop is very strange and I don't know where to begin. The laptop doesn't panic, tha fans run normal even when the kernel is 100%. If I reset the SMS, will run normal for about 30 to 1 hour then the kernel_task goes to 95% and the laptop become unusable. If I reset the sms agail will run again normally for some time. I thought is the battery,...

                Meaco Arete One / Deye Dehumidifier not working
                by CG2
                I've got a dehumidifier that has stopped working. Plug it in, press the power switch, and it beeps 5 times. Nothing showing in the display (which is just two 7 segment displays) apart from the two decimal points flashing. The model is a MeacoDry Arete One 18L, which seems to be a rebadged Deye (all the boards are marked Deye). Here's what I've got so far (details in case anyone else in future should need them).

                Starting with the power board. Mains power comes in at the red connector top left. The compressor is powered by the orange connector to the right of that and is switched by...

                ASRock H81M-DG4 power cycles and glitches - sometimes POSTs sometimes not
                by angeloavv
                Hello everyone! This is my first post and this motherboard is driving me crazy because everything looks so non-trivial that I don't know where to start investigating. During these days I believe I watched half of the YouTube videos trying to understand how to troubleshoot power cycles but at the same time, I'm confused because my motherboard doesn't always do that and sometimes completes the POST for a few seconds: the right amount of time to freeze, show glitches on the screen, and then reset itself.

                Let me give you a bit more context to understand why and how we got here.
