2007 dodge nitro so the fuses for my door locks and wiper pump keep blowing. Took the fuse box out checked all the wires. There is no exposed wires or wires crossing. Anything else it could be.

What # fuse's J5 25amp , J4 25amp , M 30 15amp , M13 20amp M33 10amp . All these fuse's are power supply's for door modules and to the wiper / washer switch . The washer pump is controlled by the totally integrated power module . I suggest you google TIPM - dodge totally integrated power module . Chrysler , Dodge , Jeep all use this componet . Also watch youtube videos on finding a automotive electrical short . That's what you have a direct short to ground on those power supply circuits

Why is audio warbled and seems slow?

Belt slippage or excessive friction in drive. Roll up sleeves and check it out.

Tv have a humming sound, sounds like a soft power saw running.

Possible that the noise can be associated with a faulty frequency in the switch mode power supply. So if you see a blurred or warbled picture then check the main capacitor in the power supply as it can be faulty and so produce the A/C ripples in he power so that the SMPS works with a difference.

There is no power to the radio it does nothing will not light up.

Check the fuse on the back of the stereo, usually 25amp blade fuse, and there could be another near the other end of the power lead. If that doesn't work, run a new earth lead (black on the back of the stereo, to any earthed metal), power lead (yellow, to a good positive terminal or to the battery), accessory lead (red, to the ignition switch or a fuse associated with it). If neither of these work then your head unit will more than likely be dead or have a security feature stopping it from powering up.

Older cobra 29ltd channel 1-32 all receive channel 20. 33-40 are ok but it transmits on the right channel also motor boats in receive on channels 16-19.

you have a bad channel synthesizer chip on the board i dont know which chip they use,as for the motorboating in the audio,you most likely have a bad electrolytic capacitor in the crossover circuitry before the audio output I.C.( can have 8 or 10 pins on them depending on which chip it uses) mounted on the side panel perpendicular to the board,they run warm,but should never run hot to the touch

Bad ground feedback?

Make sure you run the Positive wire from battery on one side,which is normaly the drivers side. Then run the remote wire and the spearkers on the passininger side. Feedback comes from two places, Your radio or your amplifiers. If running to amps always run sepert positive wires with 25amp fuses on each. For the ground (8g) and power wires are always best at 4g or 8g wiring. The ground wire must go to a clean spot of metal that is ether the frame or chasey of the car. Plus use metal srew to mount the ground wire. If it is not giving you feedback then thats a good ground which is ok to mount 2 or 3 amps max. If you still hear feedback, it's time to look at the radio and make sure the ground wire is good.

The Cause of Problem:

The Power Buttons electrical circle sometimes just braked it by one of sensors and the result is the 2 beeps and Power Supply is in protected mode error.

The whole computer is turn off but the power button is turn on and this is the nub of the matter. Because if you want turn on the computer you can't because already turn on but just the Power button and you can't do anything.

The solution:
You need just change the Power Supply and don't do anything just the power cable put into the Power Supply after turn off computer.
Finaly change back the Power Supply.

Dlp tv will not "fire up"

if your tv is on warranty take it back to the supplier.the problem with your tv is in the power supply there is a open regulator in that circuit along with the H .O. Transistor there is a black that feeds from the HOT to the flyback which also needs to check probably it is also open.good luck my friend
