Yamaha CP 300 broken headphone jack

Some keyboards use the amp output sockets for headphone use.
You might need some adapters for your headphones.
If it fell in, you would see an empty hole. This would be unlikely because it is held on by two screws. If all fails, buy an amp with a headphone jack input. Plug the keyboard into the amp and use the amps jack.

Input jack fell inside

Yes, the jack MAY actually be broken. It will need to be serviced. Run cables through the handle to avoid plugs from being yanked sideways and breaking the jacks.

I want to use the Amp inputs on the rear panel. I require the jumper plugs. I have lost these as I have been using a mixer up to now. Can you help locate some please??

If you're trying you connect the LINE OUTPUT RCA jacks to the PREAMP INPUT RCA jacks, but lost the jumpers that used to connect the two, you can simply buy the shortest RCA patch cables you can find, and plug them in Left IN to Left OUT, Right IN to Right OUT, etc. The jumpers look like the two installed between RCA jacks below.


Do this for as many jumpers that you are missing.

Need the manual to find out how to setup AV3 & AV4 as Component input, or if it is compatible with standard component input. Does not seem to work

Well, lets start here first. I would like you to look at the input jacks for a/v3 and a/v4 and see if they are color coded RED-GREEN-BLUE. or if they are just YELLOW-RED&WHITE (audio). If they are RGB then just buy RGB cables at your local Best Buy. If any are just Yellow and Red & White then those are just regular composite video the same as the old vcr's. You can't make A/V jacks work like RGB component jacks.

Powerjack is loose when plugging in power,no lights battery can not be charged.

In order to fix this problem, you will have to fully disassemble your laptop to get access to the motherboard & the power jack. If the power jack is not broken but only loose, you can re-solder it to the motherboard. Otherwise, you will need to buy a replacement power jack (usually less than US$ 10), de-solder the broken power jack, & then solder in the new one.
When this is done, re-assemble back your laptop.

Ive got a 4 way amp the one block of two outlets nos 3 and 4 are working but 1 and 2 arnt?

check the channel mode switch on the amp it goes from 2 - 3 -4 make sure it's on 2 if your only using 2 audio jacks if that don't work check connections directly from that channel to speaker or jacks from player. jacks could be broken on inside if excessive pulling was made during installation if none of those are ur problem get the amp checked out

I Have the fender 212 soild state amp.When I plug my guitar in to the input.One of two things happen ethier no sound or a hum.I have had this amp in the shop .Had it returned to me and still the same...

You likely have a bad input jack. A VERY common thing with these. They don't like to work on the jack because one has to remove too much to replace it. Lazy shop! Sometimes the solder has just broken loose or the board pads damaged. Replace the jack anyway as they take a beating.

Find a shop willing to work on it properly and DON'T accept it back until it is fixed!

Another problem with amps can be the preamp output jack switch which fails to close leaving the amp dead... but it usually won't hum much when that happens.

HINT: Loop your instrument cord through the handle so when you trip and yank on the cord it won't break the input jack... saves a lot of jack repairs!

R40 piece is missing is that a problem

Hello crzykd129,

If a piece of a resistor has broken off, it's value has changed which affects other things in the circuit. It needs to be replaced with a new component to restore proper operation. The remaining portion is being severly overburdened everytime you power it on and it's just a matter of time until it causes some other part to fail.

Resistors are generic so try locating it by resistance value (indicated by the color coded bands), and wattage and replace it. Here's a source for all types of electronic components.

Hope this helps.

Hooking up system using HI-INPUT amp wires.

This may sound dumb, but are there any other inputs left on the amp? Most amps that i have worked with have a special set of inputs for high input. (by high input you mean speaker level right?) If those exist the obvious answer is to use those. They should be labeled, so just hook them up according to them. You may need a special adapter from the amp manufacturer. If you dont have any high level inputs or any not broken inputs left you have two options. You can either A: junk the amp or B: open it up and solder new connectors back on. (it sounds harder than it really is. There are four large pieces of metal to solder onto the board for a set of inputs)

Broken RCA / phono jack - where to find new part?

You can buy Panel mount RCA (Phono) jacks at Radioshack, I think a 4 pack is less than 5 bucks, That should take care of your problem.

Good Luck,
