Repair rc car circuit board Videos

+historyskyz Thanks for the info.

+Jack Scarpon Unfortunately this is the downfall of the H8C... a nice powerfull 7.4v system with motors being week point. Not sure if a manufacturer has made more durable motors in this size yet sorry.

+Dustin Dunnill Many thanks.

You can open and check connections. Also if lipos are discharged too low they can show wrong cell count. You could try charging a little at 1s then switch to 2s and see if it sees the correct cells.

Plug it into a smart charger and charge it. It will not last as long. But it will work fine for a while until you get a new battery.

+Dustin Dunnill Dobermandan is right.Dustin, you're also right that most lipos don't have circuit boards, but most 2 or more cell lipos do have a balance plug for charging individual cells.As the battery pack ages, individual cells often degrade at different rates. When charging 2S or more in series, without balance charging, If one cell can't be charged up to 4.2v, the other cells will get overcharged (and possibly explode). So in your 7.4v lipo's case, let's say one cell goes bad and can't be charged correctly. The other cell has to take up the "slack" because the whole pack will be charged up to 8.4v, rather than each cell being charged up to 4.2v. And without a balance plug, there's no way of checking if the individual cells are balanced.So Dobermandan is not joking when he says you're risking burning down your house. This is very serious, so please do some more research if you're still not clear on it.If a 2S pack doesn't have a balance plug, then there's a very good reason it has a circuit board, and bypassing it is asking for trouble. Don't do it.

+Dobemandan Somtimes you gotta risk it to get the biscuit

hows that? Please enlighten us. Most lipos have no circuit board. Have you had any lipos besides these toy versions?

as long as you connect correctly as shown in video, the MAH does not matter. yes.

+Keyshaun Thompson You have to get one that doesn't come with RC, then you put it on the same way.

+AbyssGTYep...Next thing you know they'll be selling birdhouse at walmart..

We all know tony did it cause he got paid

Blind I think? They're all pretty similar. The Circuit Boards are more the size of finger boards too.

+Leo Newt what kind a tech deck you have?

+John Frank I have a tech deck and these are better. They are somewhere in between wooden fingerboards and tech decks.

Just do tech deck this is cheap I would only use this for ramps

Watch YouTube vids

This video saved me a ton of money! Although my Stanley was somewhat different, it was still fairly easy to do. Your video gave me the confidence to do it myself. I had to pay a garage door repairman $75 to tell me that he would not fix, but replace & install an entire NEW opener unit for $500 - $600. I found a replacement circuit board online with S & H for about $60, so over all, I'm only out $135. Much thanks!!!!

The logic board is packaged in a an anti-static board for a reason. Unless the exposed electronic item and the person handling it are properly grounded, one should never touch a circuit board for risk of ESD damage. The handling of the replacement logic board in the video is more of an example of what not to do. Other than that, yeah, replacing the logic board is that easy.

Dan- How can I tell if the circuit board is the problem? I just replaced the drive gear which was worn out. The door opened once but then did not even seem to get power to even activate the motor. When I hit the opener button, I get a little click but that is it. Help

This is an excellent tutorial on how to change out a logic board on a Chamberlain Liftmaster garage door opener. My opener has been giving me fits for some time. I figured it was the logic board but it always appeared too difficult to replace. This made the job easy.

I came here to find out how to open the housing so I can have a look at the bulb receptacle and from the looks of things I only need to deal with the front of the opener - in either case, nice tutorial done with calmness a beginner like me appreciates. Thank you

My bulb on my garage door opener goes in and out it is not burned out t bulb it is like a short in the light socket. Will replacing the circuit board fix it

how to find out if the circuit board needed to replace.mine garage works fine suddenely stop.just click and click.now more moving

Sir. would like to ask if the garage door has to be open or closed manually is it also because of the circuit board too

My remote doesn't work unless I'm next to the door. I have replaced the battery, so that's not it

do you have to relearn the rolling codes if you replace the circuit board

Thanks for the instructional video. It helped me fix my opener!

Is there a simple way to tell if your logic board is broken?
