If the output are good, Check for a bad/loose ground. Check the solder near the input jacks, and tighten any and all ground screws that hold the circuit boards to the chassis. It could also be a bad transistor in the protection circuit.

Lincoln sp-150 idealarc will not arc any more ground output checked ok fuses checked ok incoming power 230v ok output term for + voltage to wire on spool nopower when trigger pressed.continuity from


There is a temperature activated switch near the transformer that will turn off control voltage until the transformer cools. There is also a fuse for the control voltage. That would explain why the motor won't run. There's a possibility that the trigger switch in the handle is bad too.

Picture ok sound through head phones only


Check the speaker/s. If the audio output by headphone is OK, and there is no audio output by the speaker; either the speaker or the audio output stage circuit will have the fault. Contact any service technician.

Picture, but no sound


Hello
Check the speaker. If it is OK, check the voltage at the audio output section. If there is voltage, and still you do not get sound output, repalce the audio output IC. OK.

Attenuated output


Since you are able to view the output i'm assuming you are using an oscilloscope and only the positive or negative half of the sine wave is displayed. The output stage will be using a complimentry pair of output transistors, one amplifies the positve half cycle the other the negative. These are driven by a driver stage (phase splitter). One side is not amplifying. First measure the pos' and neg' LT supply rails. If ok check
ouput transistors with analog Ohm meter for base / emitter / collector continuity. If the amp uses an output IC and LT supplies are ok then use scope to view input signal, if input ok but output bad then IC is suspect. Since both channels are affected your problem is most likely a missing LT supply rail.

Kenwood ks-122 in-dash car stereo/cd changer


hello chevi1981..what can happen is if whoever installed your system did not run your speaker wires properly eg if they have worn through and touching metal or a screw through the wires ,it can blow the audio ics in unit resulting in no sound.all these high powered units have above ground circuits in the audio stage .to check ,hook up a separate speaker direct to your unit,separate wiring ,if no sound, will most likely be the intergrated circuits..these will have to be changed by a tech as cd players are a beast to work on,also your 2 speaker wires should not touch one another.with your sec code if your have a removable face you may not have a code ,as removing face is your security .hope this helps

Tv set won't start up


as your reg. output is 40v & you have checked every possible things responsible for it. my suggetion is that first you isolate power supply from hor.section & see if power supply output is ok. if it is ok then check for short & leakage in h/output like 1 hor.output tr. 2 diode or cap in eht winding. 3 check for print near eht transformer. 4 disconnect yoke connector & check . 5 & finally eht or flyback transformer.
