Comment on Fix an LCD Monitor by Patrik

There’s a whole forum dedicated to this problem lol. badcaps.net/forum
I’ve been registered there since 2007. Tried fixing a computer mainboard with bad caps and ended up kinda getting addicted to fixing stuff. Since then, I’ve fixed countless (well over 100) defective LCD monitors that I’ve bought dirt cheap on ebay or gotten for free because they were about to end up in the trash.
Similar story on LCD TVs, a bunch of computer mainboards and especially powersupplies and even some home audio gear.

All the big name manufacturers keep on using crappy caps in their equipment (especially computer monitors and TVs), most notably Samsung with their garbage “Samwha” and “Sam Young” caps and LG with their constant grab bag of junk caps like Su’scon, Capxon, Hermei, etc. :/

This just screams “planned obsolescence” to me.. especially because the majority of electronic devices (like DVR’s, monitors, TVs, etc.) seems to die half a year or so after the warranty runs out..
And yes.. if the bad capacitors didn’t damage anything down the road, replacing them is usually all that’s needed to make the device in question work again.

I made two of these. One from coat hangers. The other from a spool of thin alluminum wire. They both are working fantastic. Am getting loads of channels.

Thank you. I have an arduino. Am waiting for 6 ervos coming from China. Your article gives me what I need to know to test them when they come in!

Bid, the 2.2k resistor should not be in series with the motor. It is simply a pull up resister so that the transistor will turn off. If it is getting hot, you have connected it wrong. Try checking your schematics. When each transistor turns on, the current goes from +5, through the motor coil, through the transistor, then to ground.

have anyone got a decent speed out of the motor using the schematic. the series resistor(2.2k) connected to output reduces current.if you use smaller resistance (50 ohm) for supply from 5-9v.the speed increases.but the heat loss from the series resistor is so high that i actually burnt my finger.

also even when i apply input current through the base the motor continues to run. the transistor is running saturated . i cant figure out why the current is flowing through the motor when the collector voltage is 0 when running saturate.

I’ve seen similar stickers on harbor freight hammers:

Do not do this or that or something
else. Always blah blah blah. Blah.

Thanks a lot for the help! I just tried the step by step procedures and now I am hoping that it works as I just fixed my adapter right now! I will keep you updated on my next post as soon as I plug it into my stereo system of my 2005 Honda CRV

I am a complete ignorant trying to find his way. I loved your tutorial but I have a big doubt.
I have two stepper motors but they only have 4 wires. Since yours has 5 I don’t know wht to do…

Would someone help me please?

Thanks,

Carlos
