TV: JVC LT-43C888 (purchased in 2018). This is a smart TV with Netflix, Youtube, Freeview and other applications via 'Viewd' app store
Problem with TV:
- Netflix stopped working so i tried to do factory reset from the TV menu.
- I confirmed on-screen but the factory reset did not happen even. It did not take me to 'first-time installation' screen as mentioned in the manual.
- After waiting for some time, the TV went into a boot loop.
- JVC logo comes on the screen and LED light flashes for some seconds, then it reboots again and the same thing happens

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 -
Hi,
Firstly I'd like to apologize if this was posted in the wrong forum (I'm new here
)
Recently I got an ASUS M5A78L-M LX board in a scrap lot. Saw one broken cap which I've replaced. No broken traces and missing components. While soldering a new cap a bit of solder got onto components bellow SB (opposite of the two lythic caps). Didn't see it and powered the board on.
I was greeted with it not starting. Came back to it a day later and shorted the PS_ON with GND to force it on. It sprung to life but with CPU stuck in reset (it was an FX 4600 I believe). Thats when I saw the...12-14-2024, 10:48 AM -

Hello everyone, Please excuse my poor English, but I'm using Google Translate ^^ I'm having a problem with the HDMI and USB ports on my 55OLED803/12. It's no longer possible to connect an HDMI device and see the picture. No matter which port I use, it only recognizes the device as an input source and displays it in the list (BD player, Fire TV, etc.). However, the actual picture doesn't appear in the same state. My home theater system also runs via the BD player - it still receives a signal and plays the sound correctly (e.g., from the TV program or an app like Netflix). This works with both HDMI...
