The set has a shorted horizontal output transistor and possibly a bad high voltage transformer. The transistor can be checked with a DVM but the transformer has to have its impedance checked with a "ringer". Also solder all stages in the drive circuit of the horizontal transistor. The power supply is making the noises because of the short on the secondary side. Thanks for using fixya.

No elecectrical won't start


hi lynn. the first thing i would check is battery and battery conection, after that, fuses . J would have to have more information about your dodge to determine what is wrong with it.( does it make any noises when u start up the engine? if you know the battery is ok but wont start up, u should listen if fuel pump is working after u turn key on in ignition. If fuel pump doesn't make any noises thats praboblay what is wrong solution : new pump

The common cause would be the power steering pump, it is rather low on fluid due to a leak in the system or it is defective.

Whiney noise


Diagnosing a noise like this is nearly impossible over the internet, have a local shop look into this noise.

All of a sudden my car won't start. The battery is good, lights work It's not clicking like it's trying to start. The engine is okay, the starter usually makes that horrible waahh whiney sound...


it can actually be your starter. many times a bad starter just wont turn at all. it can be that, a short, or the only other thing i can think of would be a blown starter fuse. you can check your fuse box in the engine compartment, it should be like a 50 to 80 amp fuse thats in a little clear box in the fuse section of your fuse compartment. hope this helps. and if fuse is good, you can try poking the starter with a stick and try to start. if it does something after poking it, then its the starter

Rear diff noise


We have to be sure where the noise is coming from, a advise you or ask someone to do the following tests:
  1. jack your both your rear tires and make sure its stable. turn your tires either manually or by shifting gear into reverse and try listening to any humming or whiny sound or vibration not only from your rear differentials but also your transmisssion and independent transfer case.
  2. Be sure it secured and will not move and will not squish you under.
  3. also check on your rear propellers, differentials for excessive play
  4. If you determined where it is coming from, check on your gear oils.
My own assesment from what you have just told us, is I would also check on your clutch system, because whiney noise only exist when you are backing up the car. I hope you would pin point which part is causing the whiney noise to save you all the headache of having it repaired.
Comment after you determine where it is coming from.
Thanks for dropping by fixya
