If a connection is made incorrectly, you’ll need to use a de-soldering braid or a solder sucker to remove the solder and reconnect the components.

Hyundai terracan car stereo has error 6 with cds, now error 3 plus amp-grd. nothing works at all anymore. how do i fix?


At least you tried. Good for you. If you want to keep going, pull it out take it apart and look for bad solder joints. It's already broke, how much more can you break it? Radios usually go bad bad from solder joints. Can you use a soldering gun? If you don't, replace the radio.

How to take out 2 bad capacitors in my magnavox modle 50f231d/37


Get a soldering iron, some solder and solder wick. Use the wick and the iron to remove the solder off of the legs of the cap. Remove the cap. Install the new cap exactly the same direction the old one was in. With solder and iron, solder the legs on to the board. Cut off the extra length of the legs and you are done.

Fdl keeps showing and my washer willnot start.


Hi,

The washer thinks the door isn't locked so it won't start a cycle. 99% of the time the problem is with the CCU circuit board, located in the machine, top, back, plastic case. Whirlpool had quality control issues with their circuit boards and in this instance there are bad solder joints, also called cold solder joints, at the point where the spade connectors and relays (5 of them) are supposed to be firmly soldered to the circuit board. These joints control communications between the door lock and also the motor control section at the bottom of the machine (usually a F11 code will show with motor problems, the same cold solder joints are to blame for that too) The cure is to remove the CCU case with circuit board, it's easier that way, then remove the circuit board and touch-up those bad solder joints I mentioned. If your not up on soldering techniques, just remove the case with circuit board and take it along with this response to a good appliance repair shop and they should be able to help you out. The solder points to touch-up are easy to spot, they are the largest solder points on the board. In the end, the removal of the CCU case takes longer than the repair. Good luck.

Washer display dl and beeps then display F and wont do anything


Hi,

The FdL code is saying there's a communication error between the CCU circuit board and the door lock. 9 times outta 10 the problem is with the CCU circuit board (inside machine, top, back, plastic case) There are bad solder joints, also called cold solder joints, at the points where the spade connectors and relays (5 of them) are supposed to be firmly soldered to the circuit board. With these bad solder joints it's hit-or-miss if the CCU board recieves the the signal that the door is locked or not, and without the door locked info going back to the board, the machine will do nothing. The cure is to remove the plastic case with the CCU board in it, it's easier that way. Once the case is out then remove the board and touch-up those solder joints I mentioned. If your not up on your soldering techniques you can remove the CCU case with board and take it, along with this response, to a good appliance repair shop and they should be able to help you out. The solder joints to be repaired are easy to spot, they are the largest solder points on the board. Good luck.

Gives an error code of dl f . already replaced door lock


Hi,

The problem is with the CCU circuit board. There are bad solder joints where the spade connectors and the relays (5 of them) are supposed to be tightly soldered to the circuit board. These bad solder joints, also called cold solder joints, are preventing communications between the door lock and the CCU board. It also allows bad communications between the CCUboard and the MCU board (motor control) that will flash a code F11. The cure is to remove the CCU case with the board in it, it's easier that way, then remove the board and touch-up those joints I mentioned. The CCU is located in the machine at the to in the back. If you're not up on your soldering techniques, you could remove the CCU case with board and take it, along with this response, to a good appliance repair shop and they should be able to help you out. Good luck.

I have a Daewoo DWD FD1233. It's brand new & 12 minutes before end of cycle it comes up with E8 as an error. The machine wont spin after that. What can i do? Lots of wet washing.


Daewoo e8 - engine error! or Bad soldering.
Remove the control panel (the one in which many connections). Remove the rear rubber compound around contacts blue relay.
Resolder them. And it will be all ok!
Or - remove the entire back of the compound and look for where the bad soldering (cold soldering ). You can see it - blackened or exfoliated. Just solder all.

I have a 55in Sony TV model KDS-55A2000. In the last few months I have gone through 4 lamps. They keep blowing out and I also lose sound when this happens. Can anyone tell me what is going on with my tv...


sounds like you have bad solder joints,some may have hairline cracks in them from overheating and you may just have to have it serviced.You can open it up and look for bad solder spots and remove the solder with solder wick and resolder it with some good solder.most places use led free solder which doesn't seem to with stand the heat.

How to solder capacitors?


Soldering capacitors is not difficult. First you will need access to the rear of the printed circuit board which has all the solder connections. I don't know which type of caps you are talking about but you must be sure to make a note of which way round the existing capacitors are seated on the board. Large value caps usually have two solder tags at one end or wires coming out of each end. If there are two solder tags at one end then the plastic sleeve on the can will usually have a series of dashes down one side - this indicates that the negative connection tag is on that side. Alternatively you may have a series of plus signs to indicate the positive connection. Caps with a wire at each end of the can will also be marked with plus and minus signs to show which way round to connect. You will need to make sure you replace the caps the correct way round.

For a soldering iron about 25 watts is usually fine for this type of work.

Suggest you also use 'solder wick' to remove the existing solder when you take out the duff caps. This is used by placing the solder wick over the joint and applying the soldering iron to the solder wick. After a short interval the solder melts underneath the wick. It is drawn into the wick and leaves a clean board. You may have to clip off any solder laden wick if there is much solder to remove.

With all the solder removed you should be able to lift off the old caps and replace with the new ones. For good joints make sure that there is no corrosion on the tags or wires. Failure to do this will result in what is known as a dry joint. It looks like a good soldered joint but will not conduct electricity.

When soldering in the new caps make sure you use resin cored electronic component solder. Other types have a high melting point and will result in bad joints. Apply the solder between the iron and the connection you wish to make. As soon as it flows and makes the joint remove the iron. You may have to apply solder on both sides if it is a tag connection.

Try not to heat up any semiconductor devices with hot solder. The usually require lower wattage irons to prevent overheating.

Just a hope - when replacing caps with a wire at each end you can sometimes clip off the old wires close to the can and use the wire left in the board to connect the new component.

Happy soldering.

Speedo dont work on audi 200 89


It's one of three things. The sensor in the transmission is bad. The wiring from the sensor to the speedometer is bad. Or the speedometer itself is bad.

Bow in tv


Hello trumpold,

The bad new is the resistor is bad. If it is reading 2 ohms its bad because the rated value is .29 ohms and 5% tolerance. I would venture to say that the convergence amplifiers have gone bad. due to excessive current. Since the deflection and convergence boards work together they might both be defective. I would first suggest that you take the TV to a qualified TV repair shop, to perform the repair, but if you what to do this yourself you will need the following items:

1) Schematic of the TV in question (www.servicemanuals.net or www.manualsparadise.com

2) Signal Generator or use the on-board Signal Generator (look in schematic for usage.

3) Multimeter (for resistance, and voltage readings)

4) soldering iron, solder, and de-soldering tools (solder wick, and de-soldering pump)

With these items you should be able to determine the components you need to change, and remember follow the instructions in the schematic exactly as to board removal.

Before reinstalling the convergence board after changing out the convergence amps and ALL (I maen ALL) biasing resistors, check for solder bridges and shorts, removing them with the solderwick.

I hope this helps

Thank you,
