Here are some pictures to see how it came out.

How?

One eBay seller have the cheapest universal plate for LCD monitors the prize is only 33 USD, anyway Jeelabs has all story…

I noticed that quite often it burns faster electronics, lamps than themselves.
I made a few holes on the body, for better cooling.
Lamps with additional cooling, had more life. Then I started to combine.
Correctly electronics from lamp which blighted associate with lamp where blighted electronics.
This practical advice, unselfishly share with friends electronics.

Advanced electronics can perform change of faulty components in step-down switch electronics:transistors, high-voltage
capacitor, rectifier diodes etc.

Also, do not dispose of faulty energy-saving bulbs I’m sure it will be found and a transistor, capacitor, or some kind of SMD component.

This is a guest post from my friend Dr.Petar Avramovski writer for the magazine Emiter. Thanks Peter for this unselfish idea and thanks to what you shared this idea with us.

The process proved to be very long and painstaking, but also very rewarding.  The steps presented here are not exact, and you will no doubt find your own way of working which is more effective in the case of any particular board.  However, I believe the basic procedure is essentially correct for the majority of boards which are too complex to reliably hand trace. Without the need to invent the process, things should progress more quickly.

For simple boards, it is probably better to use pencil and paper to draw the board onto squared paper, replacing components with their symbols, and changing track crossing places to avoid components.

So enjoy..

Thank you Petar.

There are spray “contact cleaners” available for this purpose, but in most cases just mixes the dirt and grime already inside with more dirt and assembly grease and may make the control operate worse than it is already.

To accomplish this we will need about $20-25 and a few hours of spare time.
