Hi, I have a Sony KDL-55V5100. None of the HDMI inputs works. I wonder if it is only the problem of the HDMI switch IC or the MCU of the mainboard. Thanks.

Re: Sony KDL-55V5100. None of the HDMI inputs works
The HDMI switch IC would be the most susceptible part regarding failure, ESD could easily damage it, but sometimes they do not use HDMI switch but instead HDMI decoder, you cannot replace decoder due to encryption keys.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I have this TV set that I spent a long time fixing it.
I finally found a shorted SMD capacitor near the plug from the PS at the main board. It was shorting one of the main voltages (can't remember which one)
I removed that capacitor, and as it has another one in parallel, I left it with only one, checked it and it seemed to work fine. The solder near that capacitor was really delicate as I pulled apart one trace so I prefered to not mess much with it after I had to air solder one small thread of copper
I didn't use that TV much at that time. Now that I'm using it,...10-06-2023, 03:00 PM -
The board is LA-F411P ,DELL 5590 ...
The screen polarises,no backlight,no image,only black screen,tried another screen,the same,so there is no backlight,but there should be an image when i shine a lamp behind the screen,but there is none...only dark screen...when screen is connected and i press F8 to turn the image over to the external monitor, the external monitor gets coloured bars ,but when i disconnect the cable from the EDP ,the HDMI picture is good...What could be the problem? I don't have another edp cable, but i measured it with meter and it comes out good...i am baffled...... -

Hello!
Looks like I fried something when my EDP cable got squeezed on the hinge. I replaced the cable but still no display. Laptop works fine with external monitor connected through HDMI and Display Port-USB C port. I took it apart and I see a burnt component. Can anyone help me identify what this component is? I tried to use schematics for another G15 but it does not match on the amount of pins and size. I attached pictures. The component has a label on it - (21A29)
Laptop is a Asus G15 Advantage Edition 2021 Laptop Ryzen 9 5980HX - 6800M... -
