Changhong Ruba 58? 4K UHD Smart LED TV (U58H7i) showing horizontal purple and blue lines. How to fix please?
I believe you can troubleshoot by following steps below:
- Check the source: Make sure that the issue is not with the source device, such as a cable box or gaming console. Try connecting a different source device to the TV to see if the issue persists.
- Check the signal strength: Weak signals can cause picture quality issues. Check the signal strength of your cable or antenna connection. If it's weak, you may need to reposition your antenna or contact your cable provider.
- Check the cables: Inspect the cables for any damage or loose connections. If you find any issues, replace the cable or reconnect it properly.
- Check the T-con board: The T-con board is responsible for driving the pixels on the screen. If the board is faulty, it can cause horizontal lines. Check the T-con board for any visible damage or burn marks. If you find any issues, you may need to replace the board.
- Check the ribbon cables: Ribbon cables connect the T-con board to the LCD panel. If these cables are loose or damaged, it can cause horizontal lines. Check the ribbon cables for any visible issues and reconnect them properly Check the LCD panel: If none of the above steps work, the issue may be with the LCD panel itself. A faulty panel can cause horizontal lines. In this case, you may need to replace the panel or contact a professional repair service.
Note: Opening the TV can be dangerous and may void your warranty. If you are not comfortable with opening the TV or performing these steps, it's best to contact a professional repair service.

I have a h p pavillion 15 notebook pc it powers on and goes to blue screen help it will not do anyting
Your laptop most likely has a corrupt file that windows needs in order to run properly.
You did not state which operating system is on the laptop so it's hard to be specific. In any case, hit the F8 key as the laptop is booting until you come to the boot selections.
From their you can boot into safe mode and see if that works. In some cases, this is all you need to do in order to reboot into normal Windows. If you see a "boot last known good configuration" boot into that instead of safe mode.
If you cannot boot into last known good configuration or safe mode, you will need to insert your windows repair disk or your Windows Installation disk and run the repair tool.
