I have a power supply from a Polaroid LCD that has a missing EC. I didn't remove it as the TV was given to me. The screen was busted so I salvaged the boards for other projects. Now it turns out I need to fix this one. Hopefully I can sell it and make a few bucks to repair another TV. The power supply is a Polaroid MLT666AMH and the missing cap is ID EC 20 located between connectors 4 and 5. Has anyone out there got one of these boards or repaired one that might know the value of the missing cap? I think I will need a 1000uf 35v therre but I am not sure. Thanks in advance for your generous assistance.

Re: need help with power supply
If you go to Google Images and search for MLT666A you'll find plenty of pictures of the board.
For example, this one looks good:
http://futuregatetech.com/Websites/f...610786651e.JPG
If you look carefully, you see there 470uF and 35v on the capacitor.
That sounds right, it has to be 35v or more because it's on the 24v output. And 470uF is a common value, typical for that diameter and height of capacitor.
On this page : http://tvpartsfixit.co.uk/?search=t2...&Search=MLT666
The first page has a picture of your board.. if you zoom in you also see a 4 right at the top, so that capacitor is also 470... it's too small to be 4700uF and too large to be 47uF.Last edited by mariushm; 03-02-2013, 07:52 PM. -
Re: need help with power supply
Dang you guys rock on the board. I spent the larger portion of this day screening different pictures of this board in hopes of finding exactly what you found in almost no time. I didn't want to make the post but sometimes you have to stop being stubborn and ask for help.
I thank you sincerely for the assistance. Now I will go dig up a 470uf 35v cap and solder in on.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?by Tynan DillI was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

by sam_sam_samI have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
by sam_sam_samI have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
by JimBanvilleThe sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...-

by CMCMHello Everybody,
Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)
Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).
The outputs marked 12v and 20v are all measuring only 1v.
The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.
The capacitors physically look clean (no bludgesor leaks) and... - Loading...
