No you could use a cap with the same UF rating and higher voltage without any issues but the uf rating must be the same.

I recently bought a 100uf 450v capacitor to replace a 68uf 450v capacitor. Unfortunately there is no power being fed to the TV when plugged in. I was told by a local TV repairman that the uf rating...


The fault to your TV might not due to a defective capacitor. A higher capacitance valued capacitor, won't do nothing wrong. But as the capacitance value increases, the size of the capacitor will too increase. That's all. Check the fuse at the power supply regulator board. If it is found opened, make sure that something wrong with the power supply regulator board. Without rectifying the fault, never replace a fuse, as it will make things worse. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name/model number/IC used, in the search box at the top right of the display window.

Tested 68uf capacitor. Is 60uf accepable range? What is minimum?


It depends on the tolerance rating of the capacitor, but usually 8uf is withing tolerance

Hello, I am trying to fix the monitor LG L1951s that does not power on, I found the 68uF*450V capacitor bad, replaced this one but problem ramains. I have measured most of the componets on the power board...


The 68UF 450 is for the primay smps driving side, are you getting about 160vdc on that cap?
The PWM IC get the kick start DC voltage from the main bridge rectifier thorough a bunch of high resistance resistor to drop the 160vdc down to aboit 15vdc, once the PWM IC start working, one the winding will be the supplying the voltage to the IC to keep it running. If the DC output side detect short cirsuits (drawing too much current) it will go into shutdown, you need to find out if the inverter circuits has short circuits. The 5vdc and the 12~18vdc power supply will be running the minute you plug it in, you can solder in a 12v bulb at the DC output that feeds the inverter circuits (you can solder it directly on the DC filter caps for the 12~18 VDC filter caps of the inverter circuits). See application notes how this IC is used.

No blown MOSFET on the primay side?

MODEL DLT37C3 KEEPS TURNING ITSELF TO STANDBY WHEN


Mine did this to. Opened up the back cover, the power circuit board is clearly visible, on it is a HUGE electrolytical capacitor 26mm in height x 35mm in diameter 150uF 450V. Changing this for a new was the cure for me. Might work for you as well! Please be careful, the capacitor can hold a high voltage even after power is off and cable removed, make sure to remove the powercord! If unsure ask someone that can solder to do it.

You will need a soldering iron (quite powerful) and some solder to change it.

No audio, no indicators but blinking green LED by power switch.


Replace elco C61 (68uF/450V) ; it is empty or almost empty.
Also remove the dark-brown glue carefully. The glue turns from light to dark brown by heat and becomes conductive (some Mohms)

TV won't turn on


If that large capacitors is defective, the TV should still power up normally but it might produce a humming noise through the speakers.
I would suggest to check very carefully the capacitors on the secondary side of the circuitry, specially the 1000uF that filter the 5vdc line.
Let me know if you require further assistance.
