If your tv does not turn on at all Look for the voltage rectifier, voltage regulator. Diodes and resisters in the power circuit. Burnt solder traces, the flyback transformer, the horizontal and vertical output transistors. and especially bulging or dry electrolytic capacitors (which is what caused all of the others to fail) The symptoms that the electrolytic capacitors need replacing are lines on the screen, and later black bars on the top and bottom of the screen. To test any semiconductor use a solder ****** and a solder gun to remove the solder gently until you can remove each part test using a multimeter on diode setting. test the legs in any order for open circuit or short circuit if you have a high reading one way and a small reading the other way then the component is good. Any component that gets hot enough to need an aluminum heat-sink is suspect.

Simpson esprit 450 washing machine. Sometimes it will do the final spin and othertimes not spin at all. The machine is 11yrs old.


Probably a timer problem but you need fault finding knowledge and a test meter to find the fault. There are a few other reasons to not spin. You haven't said if you have a test meter or fault finding skills.

Kenmore dishwasher is flashing E2f2


duplicate question > This appears to be another ... posting same answers

Appliances branded with the Kenmore logo and sold through Sears are produced by other major manufacturers.
So First: Using the Sears Model Prefix Chart, find out which manufacturer produced your appliance to find the right repair information. Locate the model number on your appliance and match up the first three digits before the decimal point of the model number to find the manufacturer.

Then search the appropriate manufacturer Fault codes to diagnose (and hopefully fix) the problem

Washer fills and washers btu won't drain or spin have already replaced the water/drain pump but still will not drain Model number is GLWS1339ESO


This applies to most washers:
Loss of power to a drain pump and /or drain valves can usually be traced to two main problem areas:
1. Faulty timer (aka rotary control) units
2. Discontinuity due to wire fatigue or loose connections.

Fault finding of #1 can be difficult, particularly if the person doing the fault finding does not have the necessary tools, and does not understand machine logic or the steps that create the whole.
Fault finding in the case of #2 is somewhat easier, since visual and/or manual inspection is a great aid. However, a multimeter is still an almost indispensable tool and allows easier fault-finding and diagnosis.
