The power button is broken how to turn ontv

Hello Andrew

You didn't specify what you mean by "Broken"

Do you mean physically broken or
It just doesn't turn the tv on?
There are separate answers for each.

1:To fix a physically broken switch you could simply open the TV up and attach 2 wires to where the switch contacts are soldered to the PCB.
Run the wires to a new switch. Probably a NO (Normally Open) type. A Round switch could be mounted easily with a drill hole through an unused area of the case. Pressing a NO switch closes the contacts momentarily to trigger the digital turn On.

2:You could remove the old switch & attempt to get an actual replacement or a similar mountable switch from a components supplier.

3:If the switch is actually physically OK and the internal contacts are working (test with multimeter) then the problem is with the digital switch mode power supply that supplies power to the main circuits.

This would probably be caused by leaky Electrolytic Capacitors on the power supply PCB.
In that case, if your up to using a soldering iron and locating the Cap's then this would be an inexpensive way to fix the TV.

Good Luck

Lg model Lgle4500 when turned on will have no audio/vid or light on button display. Only the click of powering on/off. have turn it on/off for several minutes before it starts working properly. ideas?

Capacitors ...LG is known for blowing capacitors just about the time the warranty runs out. If you can see the capacitors in the lower left / middle, bludged & or black ...they are blown. If you r handy, you can fix it yourself. Pick up a soldering iron & solder (garage sales cheap, this time of year). Mouser Electronics or EBay will have what you need. Take a picture before u start to unplug anything. Pay attention to negative side & the size u remove from board. I have fixed about 5 of these now & it's always the capacitors.
I hope this helps,

Need advice on capacitor purchase for pentair spa pump

There are so many models of what may appear like the same motor, but the internals may vary????
If you can take off the cover & look at the capacitor itself, that is your best bet. You need to at least be at the equivalent of the same range of MFD!!!! Example 72 - 93 MFD!
You can go slightly higher, but not by much!
If you can't read what you currently have, then contact Pentair directly. They may be able to assist you with the right information.

I have a Yamaha RX-V630 Amp/Tuner. It recently blew or burned up another capacitor. Second time in about 4 years. What coukd possibly be making this amp do that. It was professionally installed. Both...

Electrolytic capacitors are known to fail due to heat over time, as they will dry out. Depending upon cost of replacement, and if you are happy with the amp (repaired), consider repair. Repair service should check voltages to ensure circuit is working properly.

If a ceramic or tantalum capacitor, look at the circuit parameters. Check the other capacitors nearby for signs of failure.

Formula to calculate rating of capacitors in airconditioners

It's not fixed formula, but as per basic rule, easy method tocalculate for motor capacitor. (2650 X full load amps) divided by supply voltage(mentionedin capacitor)= MFD. (Plus or minus 10% to 15%) Ex: 1 Tr which gives full load amps of 6 amps (2650 X 6)=15900 divided by 240(VAC)volts=66.25MFD (10% to 15% plus or minus) You can fix 56.32 mfd or 76.18mfd So, you can go in between 56.32 mfd and 76.18 mfd. If you calculate of 440VAC capacitor, it will be 36 mfd. Hope, it will be helpful . Thanks.

Why does my sub and amp go into protected mode when i turn my headlights on


Devices go in protect mode when a fault condition is detected. These include insufficien voltage, excessive load, shorts and contact, overheating.

In your case the problem is usually excessive power draw. A contact in wiring can also cause the problem, but this is far less common.

Use a capacitor fix the excessive power draw from the amp and sub.

Check your mute on /off status through your remote. If it is changing status & no sound,
It looks like sound circuit problem.Contact service center for assistance.

Loud hum out of BaseCube 12 subwoofer

Actually I"m having the same problem. It is most probably the capacitors on the power supply internally. they are known to dry out and go back. cheap easy fix by a competent electronics repair facility. Also Cambridge will fix it for $75 plus shipping

How to fix a popping sound

This problem could be a normal thing in the amp, or there could be a problem in the muting circuit. I would contact the manufacturer to check with them , if theres any common issues with this amp. Also I've seen custom car amp installs where you hook up a speaker delay circuit that you can build from a few parts like a couple of capacitors a few resistors , a 555 timer IC and a relay with high current contacts. I have also seen these already factory nmade in good auto stereo shops. Good Luck
