No inputs work except component

01-18-2011, 11:53 PM

Basically none of the inputs of my Toshiba 57H81 tv work except for the component inputs. Anything else hooked up, including coax cable, results in a distorted video with little to zero audio. Is there something I can do to fix this? Personally I just want the coax cable to work so I can watch tv, so if this is possible I'd be fine with that. Thanks so much for your time.

*The TV was gifted to me by family for college, this has been a known problem however it's been kept amazing shape so abuse is unlikely.

Re: No inputs work except component

Apparently my tv has a bad scan converter board. Any idea on how I could replace it myself?

ASUS ROG Strix G713QR - Keyboard, backlight and side LEDs don't work

by hollox123

Hello, I have an "ASUS ROG Strix G713QR" laptop, and for approx. 3 months I have the following problems:

1. Laptop keyboard doesn't work
2. The backlight on the laptop keyboard doesn't work
3. The x2 side LEDs (red) on the laptop don't work

The power button works, the touchpad works, and all the USB, HDMI, Ethernet, etc. ports work.

I already tried to reinstall all the drivers and reinstall Windows. So I don't know what to try anymore that is software-related.

But I am strongly aiming that it is somehow a BIOS-related problem,...

lenovo 330s-15ikb, led num lock key always on and numbers don't work

by resistor83

hello everyone, I have a particular problem with this lenovo ideapad 330s-15ikb. I had to replace the motherboard due to liquid damage, after replacing it I noticed that some letters on the keyboard do not work. So I bought a new keyboard and now all the keys work except the numeric keypad area. In practice the num lock key LED always remains on and the numbers do not work. Has anything like this ever happened to you? I also tried changing the keyboard again but the same defect remains on the numeric keypad.

I tried updating the bios but the problem remains

DYMO Rhino 5200 Industrial Label Maker that the backlight does not work any ideas

by sam_sam_sam

I just bought a used one for a decent price for a used device it prints very nicely and clean and clearly so I am not going to complain about it but I would like to get it working again anyone have any suggestions on how to repair this back light

If I can not get the controller to work properly then I will probably have an external power supply for the backlight because it is difficult to see the screen without out it

One —>the LEDs might be bad
Two —> the buck converter or regular might be bad
Three —> the controller might not...

My touchpad doesn't work, Asus laptop motherboard X455LJ REV 3.1

by Rhaverz

Good afternoon friends

I have an Asus laptop motherboard X455LJ REV 3.1 that the touch pad does not work, I was trying to check if something was wrong at the drive level but I did all the necessary installations and the touchpad still does not work.

I have a feeling that the error goes more to the board level because the touchpad is not recognized by the device manager and it is supposed that even if it does not work correctly it has to be detected.

I even checked that the data bus made a connection between the touchpad and the motherboard and everything...
