My Samsung 42 inch does not switch on but the red standby light is on.

The most likely problem is the power supply has leaking or bad capacitors. Look at the power supply board and see if there are any leaking(oily looking) or bulging capcitors. Simply replace them with same value capcitors and you should be ready to go.

How to repair a LCD monitor?

Do you have a hammer?
then don't use it!

Usually LCD monitors won't power on or flash light or just have a very low light on them.
Mostly it is due to capasitors melfunctionaing.
You can, if you have the know how, to open the screen it self. Do it carefully since usually the plastic bazel is held by plastic hinges that tend to be brittle.

Check the boards and find the capacitor that seems to have "Bloated" (it won't be flat like the rest).
you will then need to change the capacitor and all the capcitors next to it with ones with equal value.

How to change the capcitor on WASHING MACHINE MOTOR WHIRLPOOL OPN 481903950297

Remove the mains plug and make sure there is no power supply to the unit. Now identify the capacitor and check the value. This is bipolar type and so you can connect any side after removing the old one and refitting with a new one.
Please check and confirm the value of the replaced one to be similar to the damaged one.

HOT transistor TT 2222burn after second replace. TV Samsung Model CS-21Z45MJ

Before replacing an other one, replace the freewheeling capacitor, the capcitor fitted between the collector of the 2222 and earth; usually of a value of 3500pf 2000VDC, some times this value may differ from set to set. If this capacitor has opened of developed in value, the result will be the failure of the horizontal output transistor, at switch ON itself. The second reason is the short in horizontal yoke windings. Even one winding get shorted, it will cause to a heavy load flyback transormer which in turn to 2222 failure. The last reason for this fault is defective Line Output Transformer itsef. Check these three.
Before proceeding, desolder out the horizontal output transistor 2222 fro circuit, and measure the frequency at the collector point of horizontal driver transistor. It should be around 15625HZ [may differ a little], with no signal. If this frequency is found higher than normal, The main IC jungle should be suspected.
Anyway, go forward after checking this frequency. OK.

My I O DATA ftv lcd television have a sound but the picture or display will not appear?

Check the power supply for buldging capacitors that are going bad especially in the inverter supply voltage, replace any caps found to be bad with same value as orginal capcitor, but make the voltage rating for each cap higher.

Horizontal black line running entire screen an 4 more lines running vertical

This type of fault in Plasma TVs are of power supply regulator capacitors. If any one of these DC capacitors, go low in rated value, proper smoothin of DC power does not occur. and black bars across the screen fro top to bottom will be the result. Just check for any capcitors of it power retulator side for bulged out or leaky. You have to open the TV to see whethere there is any of them is damaged. OK.

I have to unplug the TV, then rub the prongs briskly against my clothes, then plug in quickly to get TV to come on.

you have a bad capcitor in the power supply they will be domed or puffed on the top the can shape devices will have the value on the side

Wont turn on right away

common problem with this one it is a bad capcitor in the power board the can shaped capacitor will have a domed top from venting the value of the device is written on the side you could or have someone replaced the part and you should be all set

My philips plasma tv model 37fd9944/01s screen clicks and then switches itself off after 1 minute and well not stay on.

Probably one of the drive boards have gone out. There are 2. An x and y. One on either side. You may want to consider the power supply as well. Capcitors like to "vent" as we say in the industry. You'll see the top of them bulged out. This causes voltages to drop below a usable value.

Fan inside the house comes on and cool air comes thru vent but fan on outside compressor wont come on is is the capcitor

It could very well be the capcitor. If you have a duel capcitor (1 cap. that is used for both the fan & the compressor) the compressor may not run either. First and easieast try the capcitor. If thats not it and the compressor is running & all wires look ok than its probebly the fan motor.
Hope this helps;
