Re: Please Help!!
What kind of components that fit into those holes? If they are through hole components, I would use 24AWG solid bare wire and wrap the wire aorund the component's legs then solder, then I would apply epoxy glue on top of it.Never stop learning

Re: Please Help!!
The thing is most of the track as come off as you can see in picture. i gave it to a mate who said he could fix it and ended up coming back looking like that.
he burnt the tracks with the soldering iron and took the track off. i just can't see where it joins as im not good at this sort of thing.

Re: Please Help!!
OK, you trying to figure out how all the legs of the components are hooked up to each other and the orientation of the transistor due to the old copper traces are gone.
Can I see the top side of the board then I may be able to figure out which hole is the the Gate of the transistor.Never stop learning

Re: Please Help!!
OK, This MOSFET is used for the RF Power amp putput stage, Pin 2 of this MOSFET is SOURCE pin instead of DRAIN pin like other MOSFET, but since it is made for RF circuits which need to have minimum stray capacitance in the construction of the silicone die and the internal lead connection, they make pin 2 (middle pin) as a source pin.
Please se picture and spec sheet on how to put this MOSFET in place.Never stop learning

Re: Please Help!!
Do you get the power before? Can I see the whole picture of the board so I can see where the power is applied and the way you have install the MOSFET?Never stop learning

Re: Please Help!!
That power cable? (the gray cable on the bottom right of the board as shown in pic1, see if there is shortes circuits there, see if you have any voltage on that blue electrolytic by that gray cable.
I see a DC input jack by the gray cable also.Never stop learning

You need the meter for sure, do not leave the power connected since you may have short circuits somewhere or you may have bad power source, power switch, etc.Never stop learning

Re: Please Help!!
Just tested it by touching the 12v dc wires straight 2 the circiut board and it powers up ok. but when trying to power up through the proper way nothing happens.Comment

by wnlewisOK. I got the rocker switch figured out thanks to the good advice on this forum.
Now I need to figure out the correct wire to go to the switch from the broiler element and from the oven element.
This is a Whirlpool RDE3340 electric range.
The common wire on the switch appears to have a high temperature insulating material. I am guessing that both the wire to the broiler and the wire to the oven elements also need relatively high temperature insulation. What do I need to look for? The broiler is rated at about 2400 watts.

by emeskayWe have an Lenovo Yoga 710 15ISK that we use as a secondary laptop. To cut a long story short, around May 2023, while traveling, I connected the laptop into an electrical outlet that was already switched on. Something made a "pfft" sound and the laptop refused to turn on after that. After getting back home, I gave the the laptop for repair to an informal repair person. He replaced the adapter and an internal motherboard part, but after he returned it I noticed that the LCD did not look normal. Essentially, every alternate horizontal line on the screen had gone missing. The laptop was...1 Photo

I currently have a customer's vintage fan on the work bench to repair.
It uses an induction motor with 4 poles. One of the poles is open.
I couldn't find the break so i cut off the original wire.
I have measured the other poles and the resistance is about 28 ohms per pole and I measured the diameter of the wire with my digital calipers and it is 0.35mm in diameter.
I need to work out how much 0.35mm diameter enamelled copper wire i need to order for it to be 28 ohms. I have used this calculator and it says i need 160.35 metres.

by GlenBrimI got this recently as-is. Gigabyte 1070 video card.
DVI port is removed. I don't know why.
A wire is soldered across two spots where it looks like the DVI port was. I don't know why.
I've read of people simply ripping out DVI ports and the rest of the cards still working fine. Never read anything about soldering a wire in there for some reason.
The card seems to work fine, except it's stuck in low clock speeds. While starting a game or benchmarking, the clocks may momentarily increase to around where they should be, then goes way back down and stays...2 Photos - Loading...
