The negative battery connection came loose from the circuit board

The remote control has space for TWO AA batteries. The cells are placed in ''series''. The negative wire (conical shaped spring) that leads to the circuit board has come loose and does not complete the circuit any longer. What is best way to resolder to a circuit board?

Will not retain presets

Many times a capacitor is used in place of an actual battery. On Harman Kardon receivers this component is on the front side circuit board behind the receivers external display. Harman Kardons website provides the actual location and part number if you dig around for the service manual PDF.

Dvd remote control sensor not working

If you are using the Player's original remote, if you have a cell phone with a camera and display or a digital camera with a LCD display, place the remote in front of the camera and press a button. If the remote is functioning, you will see a red flashing light on your camera screen. If not, check the remote's batteries and connections at the battery location for corrosion. Beyond that, there's not much else to check. Generally, the IR receiver in the players don't go bad, but it's possible. If it's an expensive unit, service is an option, if not, it's cheaper to replace. DVD players start under $50 for an ok model.

Try fixing your remote controller, because sometimes when we neglected to replace our remote batteries for a while, it will leak and it will build up on the contacts of the remote pad.

Take off the battery, open the back of your remote, lift the circuit board, clean the green painted part with cotton balls slightly damp with rubbing alcohol as well as the black thingy behind your remote pad, let it dry put it back together, replace with a new battery and try if it works.

Good luck

Tv does not respond to the remote with sound

The most common solution to your problem is to install new batteries to the remote. Also sometimes the batteries are loose, fix this by putting a card board wedge between the batteries and the battery cover.If this does not work try reprograming your remote.

Sony ICF SW55 always OFF

I have the same radio.

It was given to me not working
I took it apart.
Was surprised about the contacts not being soldered
After re assembly and with new AA nicads it started.

First it would take clock and then go off
losing clock settings.
then it comes on and starts fro factory CAL menu.
after repeating many times now coming on with all functions
volume not great
sensitivity/signal strength good
Now after recharging batteries stays on and last longer.

It appears that resistance/poor contact with circuit board of battery connections causes l;oss of voltage.

Suggest follow these steps cleaning with solution and may be also re tensioning contact contact areas.


good luck

Mm50 battery dead

If you take out the 8 screws on the back of the mm50 it comes apart easily. The one 18650 rechargeable battery is held in by two screws and 1 connection on the circuit board. Pull the connector out and unsolder all leads. Solder in a new 18650 battery in its place and put it all back together. OR.. For MORE power... Solder in an extra 18650 battery in parallel with the original. DO NOT forget to solder back in the Protection Circuit Module that is in place there... Or you can order another one from a place alike

Just a thought, but maybe even the new batteries aren't making good contact (you have replaced the batteries, right?).

Remove the batteries, using a cotton swab and alchohol, clean the contacts in the remote. Then install fresh batteries.

If that does not remedy the problem, you may be able to locate a used remote for your model. Do a google search for remote control resellers, or check a popular auction site.
