So I bought a lenovo tablet for dirt cheap and I'm trying to fix it. I think it's from either the cable or the connector on the lcd screen. Both cable and connector look fine. I've opened the device and apply pressure where connector and cable meet and by holding my finger there it fixes it. I have cleaned both connector and the cable with isopropyl alcohol and it's still the same. The line are mostly red sometimes green and cover the whole screen. Touchscreen still works fine and so are the speakers. And this happens sometimes. The lcd flickering usually happens when my tablet is being moved.

My LVAC 200 wont stay on for more than a few seconds. I have only had it for about a month.

Hello everyone, i'm new to the forum, and i was thinking about certain things, but first let me tell you a little about myself.

I'm 25, currently finishing my EE studies and i love electronics. Apart from designing a few PCBs and fixing a few minor electronic devices, coupled with some soldering skills, i was wandering about a side hustle. Looking at broken electronics including gaming consoles, tvs, phones, guitar amps and other, i wondered is there a way to earn money buying those broken things, repairing them and then reselling them?

I know that i have to find a niche that would suit me well, but i'm struggling to find answers about what niche is not too hard to get into and that can earn some side hustle money?

Sorry if this question is out of place or if it's not suitable for this kind of forum, i'm a bit on my own in this journey. Thank you in advance!

My phone fell since then and I have only had problems with network and range. Some places not much and sometimes not at all, someone can help me where the problem may be so that I can solve it

It seems like dropping your phone may have caused issues with your network connectivity. Here's a brief guide:

1. Check for physical damage:
   • Dropping your phone could have damaged its internal components, including the antenna or network receiver.
   • Inspect the phone for any visible damage, such as cracks or dents.
2. Restart your phone:
   • Sometimes, a simple restart can resolve temporary network issues.
   • Power off your phone, wait a few seconds, then power it back on to see if the network connectivity improves.
3. Reset network settings:
   • If restarting doesn't help, try resetting your phone's network settings.
   • This will remove saved Wi-Fi networks, Bluetooth connections, and cellular settings, so you'll need to re-enter them.
   • Look for "Reset Network Settings" in your phone's settings menu.
4. Update software:
   • Ensure your phone's operating system is up to date.
   • Manufacturers often release software updates to fix bugs and improve performance, including network connectivity.

By following these steps, you can troubleshoot and potentially resolve the network connectivity issues caused by dropping your phone.

My 2017 27" iMac had the logic board replaced just over 12 months ago. It was working fine after that. I moved overseas, and it went into shipping for 3 months. On getting it back about a fortnight ago, it would not start. Where I am currently stationed, there are no Apple Stores or approved Repairers.

SYMPTOMS

• Power switch works, and fans come on.
• No startup chime.
• Nothing on display (remains black).
• If I power it down by holding power button, it turns off, but then starts back up again after a few seconds. I have to remove power cable immediately it turns off to keep it off.

DIAGNOSTICS

• I have removed the RAM. If I try to start it up without RAM, it produces the 'no RAM' beep, but symptoms remain the same.
• I have removed the display screen. LED 1 lights up when power cable is plugged in. LED 2 lights up when I press the power button. Fans run high (as expected with no display). LEDs 3 & 4 do not light up.
• There does not seem to be any obvious damage or poorly connected cables on the inside, although I have not yet taken off anything other than the display screen.

WAY AHEAD

• I cannot replace the iMac, nor can I get one shipped to me, due to where I am currently deployed.
• Is there a PRAM battery in these models that could possibly be drained down after 3 months unplugged? Could that cause the symptoms?
• Is my only option to get hold of a new logic board and replace? Sadly, that is probably more expensive than the iMac is worth.

Thanks to anyone who has any helpful advice on what to do next.

I thought I would update this question. Unfortunately, it is not good news.

I managed to source a second hand logic board that I was told was working.

I followed the guide, removed my old logic board, and replaced it with a new one. Same SSD, same RAM, same screen, same PSU. On startup, there are exactly the same diagnostics as above. Now, it might be that the 'new' logic board has the same graphics chip problem as my previous one. However, is there anything else that could cause this symptom?

Thanks again for your time.

Sorry for incorrect phone model, but I couldn't find my phone model in the list of models, so I just went with the one that most closely resembles my phone. I have a T-mobile Revvl 4, and the phone says that it's charging when it's not and the screen just randomly turns black, and it's had issues like this for 9 months. I have to constantly turn it off and then back on again to get it to temporarily work again. However, then the screen just turns black again, and the issue continues. My phone briefly stopped having the issue for about 2.5 months. On December 14, it was raining and only a little bit of rain got on my phone, but not enough to cause any water damage. I'm not sure if it's because of the rain or not, but now it's going back to saying that it's charging even when it's not, and the screen is randomly going black again.
