Turning off

SOURCE: 50v 100uf capacitor

The problem is a $1.09 part. You will need a soldering gun, multimeter, etc.. Or someone else who is electronically inclined.

The fix for it is here:

Ofcourse test the Va voltage before attempting the fix. My Va had around 10V and should have been around 70V.

I have the 46" Dell model with the same problem, Dell Logo all pixilated and fading out to black screen, and this fixed it. Part cost $1.09 plus shipping.

I can't take credit for this persons post so post thanks on the fix.

Just note, TV's can hold electricity even after being unplugged. So if you try this keep that in mind. You shouldn't mess with it until an hour or so after you unplug it and even then there could be electricity in the large capacitors that can harm or kill you. Google "discharging capacitors" to discharge the electricity from the power board. Attempt at your own risk.

SOURCE: i have a westinghouse sk19h210s will not turn on.

their right volt rate will not matter as long as it is higher do you have any other indecation of the unit getting power? if not check you fuses if so you mainboard could be your problem check carfully for more bad caps

SOURCE: Failed Repair Job. A friend of mine called a

replacing the 10V caps with 25V caps is perfectly fine. In fact, if it was manufactured like that, those caps may not have blown.
Replacing a 680uF with a 1000uF could be problematic depending on it's function.
680uF is pretty specific when 500uF and 1000uF are much more common and therefore cheaper - one would think that the engineers would have tried using those in the design rather than a 680uF - makes me think the value of the cap is important to the frequency of the circuit it's in.
Other concerns might be whether he got any of them in backwards or not.
That's a rookie mistake, but still an easy enough one to make (for a rookie).
Also, with that many swollen caps, I wonder if there were any that leaked out the bottom before swelling at the top (IE - if some caps were missed in the replacement procedure)
Also, with that large a number of caps gone, other components may have been compromised or blown.
I'd be testing the transistors around those caps (most likely punched through rather than open), looking for fusible links (surface mount fuses, 0 OHM resistors) that may have opened up etc.
The initial attack on the problem was basically correct, and in many cases probably would have fixed it (if say the 680uF cap was functioning as a ripple filter).
But when that didn't fix it, a deeper analysis should have been done to complete the repair (including locating a 680uF cap).

Testimonial: "Excellent and through description of recommendations."

SOURCE: Want to know if I

NO. The capacitance must be the same. The voltage can be higher but never lower.
So you will need a capacitor of 680uf 50v. A capacitor with a higher voltage rating will work. They just cost more.
So for the power supply;
> Use ones with the Low Equivalent Series Resistance ESR rating
> Use ones with the same farad rating
> Use ones with the same or higher voltage rating
> Use ones with high temperature rating
Give this information to your parts supplier and they will get the right part.

A temperature rating is not an electrical rating, and will not directly affect the electrical characteristics of the circuit. Higher temperature ratings only mean that the component will withstand higher temperatures. This can help provide stability to the electrical characteristics when the circuit is exposed to the higher temperature, and of course provide better longevity as a result.

Most electrical / electronic components that have values that can be changed usually can be changed to HIGHER values, nearly never a lower one. Capacitors may be substituted with others that have higher ratings in temperature, accuracy and voltage. Their unit of measure is the farad. In some very specific cases, even the farad rating can be increased. Inductors are similar to capacitors. Their unit of measure is the Henry. The Henry value, like the farad, should remain a constant. Like the farad, the Henry value as a rule however should not be deviated unless you know what you are doing. Resistors can have their wattage and accuracy values RAISED freely without fear of adversely changing the circuit. Increasing them usually provides better stability.

So, why not use components with these higher, more desirable values? Easy! Space and money. The higher wattage values require more space as they device is physically larger to dissipate the heat. Higher accuracy requires tighter controls on raw material grading and production processes.. all of this translates to more labor and higher costs. It doesn't make sense to buy an expensive 100v rated capacitor for use on a 5v circuit - when a 20v capacitor will be more than adequate - for a fraction of the cost.

I hope this helps and good luck! please rate my reply. thanks.
