I'm guessing that you've already taken a look at Apple logo then blue screen since you mentioned that you checked for long screw damage and most of that thread talks about screw issues. Since this seems to have begun occuring without any obvious precursor (droping the phone, water damage, repair gone wrong) it could be a software issue. I read through this article and it seemed helpful: http://vkrepair.com/iphone-5s-blue-screen/ There is a section on software solutions that recommends the following. First try: (1) Press the home button and the lock button at the same time and hold them until your iPhone 5S shut down. (2) Power on the iPhone. (3) When you see the Apple Logo, press the volume up button until it boots up. This might take a few tries. You may have to hold onto the volume button for a few minutes. If you're still having trouble, you may have to reinstall the iOS on the device completely. To do this; (1) Plug the iPhone into your computer. (2) Power it down by holding the home and lock buttons....

Have you tried fiddling with the settings on your TV? You should be able to adjust screen brightness by clicking the 'Menu' button on your TV or remote and selecting the setting called 'Brightness'. You can also adjust the color in this same menu.

Hi @knhoffman. Since it sounds like your touch pad is still functioning, I would guess that it is your LCD that is broken. That being said, the LCD and digitizer tend to be sold as a single unit and it generally makes more sense to replace both parts at the same time. We have a great repair guide that shows you how: Remplacement de l'écran complet du Samsung Galaxy S4 If you want a little more information, a very similar question was asked before that got a lot of great replies.

Hi @scott76, how long have you had the phone for? Batteries do have a finite lifetime of about 2-3 years or 300-500 charge cycles. So, if you've surpassed that lifetime - it's possible that you need a replacement battery. Did anything in particular happen to damage the phone in anyway? Was it dropped? or perhaps exposed to moisture?

Hello, hizeada. Error code 32 corresponds with an open lamp cover. If your lamp cover is in fact closed, then chances are the lamp cover is either not installed properly or the lamp door switch simply isn't working. You can try to troubleshoot this by removing both the lamp cover and the entire rear cover. First, check the operation of the switch. You want to ensure that the long lever part of the switch is not broken and is in the correct position to make contact with the lamp cover when everything is reassembled. If the switch seems to be in good condition, go ahead and reinstall the rear cover and lamp cover and check to see if you are still getting the same error.

From the information that you have given, my best guess is that the side panel buttons on your TV are malfunctioning. It sounds like @oldturkey03 had the same idea. If this is the cause of your issue, a temporary solution might be to simply disconnect that panel completely, and only use your remote to control power, volume, etc. If you take the back off your TV and locate where the side panel buttons are, you should be able to see a wire connecting the panel to the button control board. Try disconnecting this wire. Let me know if disconnecting the panel fixes the volume fluctuation issue. If it does, you may want to consider looking for a replacement. At that point I can try and help you find the part online! Good Luck!
