Insignia cd player model ns-p4113

CD player works well and sounds good while on battery power. The instant that I plug in the 4.5v dc cord, powered by the car's cigarette lighter, the unit shuts off completely. The cord indicates powered with a green light illuminated at the lighter's plug-in end. Any suggestions as to the problem? I don't want to keep buying batteries if it can take an external power source.

SOURCE: No Power

in your power board near the back of transformer you have a backup power source of 5volts. that is for the cpu and the power relay swicth. can you check if you have that 5volts present. What i can see only in your unit is a major brekadown of your main amp section, all power transistros must be busted/shorted, and no chance even for a click on the relay. that is also feature of the protection. you wont be able to get the unit started even for a while. the fuses for yamaha do not normally blow and very often only your protection circuits enables. but in your case it is a very bad output stage now that you dont even get the display on to see the trouble in the built in diagnosis.

SOURCE: Power on problem

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

SOURCE: Sony Str-DE945 5.1 not Powering Up all !

It's possible there are several bad solder joints on the front panel PC Board which can cause non responding controls, loss of sound. I repaired mine that way. Try turning it on with remote, see if that works.

SOURCE: I have bought an used Nakamichi AV1. The unit

I also have an AV-1. I suspect you might be missing the pair of bridging pins (looks like a shiny u-shaped stubby nail) inserted between the center of the "Pre-Out" and "Main In" rca connectors on the back of the unit. There are two sets, one set of left and right each for the Front and Rear. Without these, you will get no output from the unit.

Hope this helps.

We can't get the NS-PDVD8 to power on when it is plugged into the car power outlet. The light to the power cord is on and we know the power outlet works. Any suggestions?

Most likely your DC power supply input jack on the NS has cracked loose from where it's soldered onto the circuit board inside.

I have an insignia T.V. that I picked up on the curb. The power cord was cut. I want to rewire a cord to it. It has a white and black line. Does the white line go to the fat plug or the thin plug in the...

it will be a DC power supply normally so i would not plug direct in the mains.

normally there is a marking on the unit of required voltage also the white line is usually + and black -

and it could be anywhere from 12v onwards

best of luck.
