Possible missing internet ribbon - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hi all,
Recently picked up a Samsung Tab 3 with a smashed screen and broken charging port. Replaced the charging port now and hooked it up to power supply. Had no life, plugged it into PC so i could hear the chime when it does turn on and it connected straight away so there is power there.
When looking at the back just now, I have the gold ribbon from the screen on the left, new black ribbon from charging port and that's all. Looking online and the back of the tablet, it looks as though there should be a third ribbon on the other side? Is this right? If so, what is that ribbon for and where could i pick one up.
If it should power on without it, will a cracked screen matter? I have not received the new screen yet but the digitizer is in good shape, ,cracked screen plugged in. Will the cracked screen matter or should i still see some life on there?

[Q] Epic 4G Charging Problems. Please help!

Hello all,
Today, I decided to take my EG4T in for repairs, as I believed the charging port was defective. After the Charging port was replaced, I attempted to charge it. When I did, I got was a faint blue light on the indicator. The screen flashed on and displayed the charging battery thing, but it flashed off just as quickly. (This occurred before I got the charging port replaced.) I tried different outlets and I am going to try different chargers later, but I want to know if this is the cause of a dead/bad battery.
If this helps, My computer reacts when I connect the phone to it, but disconnects when the screen turns off.
It also got very hot prior to the point of not charging at all.
Thanks in advance,
Arius.
It could be a bad battery, but it sounds like what happened when one of my battery connection pins was pushed in too far, used a paper clip to pull it back out and no problems since.

Menu & Back Buttons not working after screen replacment.

Recently dropped my GT-I9195. Surprisingly from about 2 feet onto hardwood floor while in a case, must have just hit it right because the screen stopped working.
After getting the replacement part, following and double checking the disassembly tutorials available online, everything except the Menu & Back buttons is working. Home button works perfectly, just not the other two, no response and no light on either.
Has anyone replaced the screen/digitizer in the past and knows what I might be missing. Any help would be great. Thanks!

Look at flex tape at left, down side of screen. It is responsible for buttons but I don't remember is it only for home or all 3 buttons. Anyway if it's connected and You didn't teared or broke this flex tape You can't fix it without tearing apart whole screen. Just ask for replace whole screen part for new one without damages.

Nexus 5x volume components

Hi,
While I dissasmbled my nexus 5x, I accidently ripped the two components of the volume- button. (You could see it in the upper side of the photo below - the first two components right to the barcode)
I belive it some kind of resistores or capacitors.
Can anybody tell me what are they and what their values?

Also,
After connecting homemade portable charger, my usb port doing problems. First it won't charge by connecting and cable that isn't the original charger, after factory reset it works without any problems.
I can now now charge it OK and also transfer files to the computer, BUT USB audio do not works constantly (5 seconds on 5 seconds off) and the same is the OTG. It seems the connections are fine (Ill re-solder them later). Anyone heard about a similar problem? What could be the cause?
Thank you!
Hello Bro. I have the similar problem: My phone got wet and when I was drying it with the heat gun, the components of volume + and - were deployed. I dont know if this can fix.

Can an old Samsung Wireless Charge cause damage to the screen?

Part of the touchscreen is now unresponsive.
The last thing that I did before it broke was charge it on my Samsung Wireless Charger.
- didn't drop the phone
- no physical damage on screen
- no recent OS software update
- screen was still working this morning -> charged on wireless charger -> suddenly became unresponsive
- tried safe mode and turning it off and on already. Will try to Factory Reset after backing up
Anyone with similar experience? Searching online points to a damaged digitizer, which requires a screen replacement.
I don't think the charger is the culprit for the unresponsiveness, I have charged all my notes up the 10+with some really old charging pads, one is an old generic one that I bought for a a note 3 back in the days!

Broken display or other problem?

I bought another broken SM-T805 and when i start it (cold start) takes about 15 seconds before the screen starts to malfunktion.
It starts to show small multi colored LCD defects on the left side and it ends up showing like you can see on the picture. The screen works to use and all other functions works.
What I can see and feel is that the temperature is sometimes a bit high on the processor and the screen. I have tried to change motherboard (SM-T800) and another battery, but the problem is still there. I havenĀ“t been able to use another LCD-cable.
What do you think? Is the display broken beyond repair or could it be another problem?

Check the ribbon cable is seated properly in the FFC connector on the motherboard
Be careful with the locking tab. Panel I guess could be faulty
For heat issues see the mod thread about using thermal pads
