Remote won't change volume, channel numbers don't work

IF its the original remote for the device, the circuit board is just dirty and is not getting good contact. If its a universal then the codes may not be 100% compatible with the device or the remote isn't 100% compatible either.

The volume on my curtis mathis television is not working properly. the numbers are low but volume is high.

There is some fault with the control section to volume circuit. Contact any experienced service technician. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

2000 buick regal. Losing fuel pump voltage

http://www.bbbind.com/free_tsb.html free wiring diagrams ! Enter vehicle info. year , make , model an engine size . Under system click on engine ,then under subsystem click on fuel controls . Then click the search button , then click blue link .The 7th diagram down shows two fuel pump relays , This I have not seen before ! One is speed cont. relay an the other is just fuel pump relay ? The speed control one has a resistor in the electrical circuit . That is way your droping voltage .
Fuel Pump Electrical Circuit Diagnosis (VIN K)
Fuel Pump Electrical Circuit Diagnosis (VIN 1)

The PCM alters fuel pump speed by energizing the fuel pump speed control relay. Under normal conditions, the fuel pump speed control relay is energized. The applied voltage to the fuel pump is controlled by a resistor assembly. When higher fuel volume is required due to increased engine load, MAP sensor value over 90 kPa the PCM de-energizes the fuel pump speed control relay circuit. The increased voltage to the in-tank fuel pump allows a higher volume of fuel to be delivered to the fuel rail. The PCM also compensates for low system voltage by energizing the fuel pump speed control relay.

Have it check for codes !

Why does the radio volume go up without turning it up?

Hello
It is an electronic component mistake in the circuit board. Even though the volume is controlled by a knob, it actually works in cnjuction with and electronci circuit, usually controlled by an IC in some sets or with a transistor with others. You have to find out the faulty component on board. It is really a skilled work. Eventhough the faulty component won't cost more, loacating it is a skilled job indeed. You must have thorough knoledge in electronics, and the schematic diagram of your set. You must have knoledge to follow the schematic diagram too. You may be pretty handy, but this is not enough find out the faulty component. Must be an expert and must have succician expereince in repairing electronic circuits. OK.

I need a volume control pot. for a RCA WHP150C 900MHz wireless headphone. I cannot find a circuit digram nor do not know how to order it by part number (since I don't have the circuit diagram). I need a...

Hello Arthur.
If the pot has an engraved / embossed / screen printed value on it you may also be able to buy an exact replacement from your local electronics component stockist.
Otherwise take it with you as a sample.
Pots are standard values, so most component stores will stock your one.
This will be cheaper and speedier than ordering one.
Regards, Clive.

An i get the diagram for the ON OFF switch and volume control? mine is damaged i like to fix it

-"Can i get the diagram for the ON OFF switch and volume control?". I built mine based on a schematic generated by tracing the printed circuit board of a working unit. Some component values are non-standard but I just used the nearest standard values. The ON/OFF switch was also replaced by a toggle switch because the original is an integral part of the volume control. The 9-pin mini DIN connector presented the greatest hurdle in my part of the world but got lucky cannibalizing a discarded Strobe Pro scanner. The completed unit worked as charm. The schematic can be found here: http://i1192.photobucket.com/albums/aa327/aguinart/Creative5200.jpg.
