I have an Insignia NS-LCD26F TV (Some places list it as a Haier) and the guy tinkered with it and it's missing some parts on the power supply. I'd like to find out what they were and replace them. The power supply part number is AD151M24. If anyone has one of these power supplies or a schematic for it, I'd appreciate it.

Re: Need Help Finding a Schematic for a PS
Did you ever find out the value of the capacitors for the Insignia NS-LCD26F TV Power Supply? I have the exact same tv and someone replaced the caps of the powersupply output and atleast one of them is obviously the wrong size in uF value and in physical dimension. -

While diagnosing one of these boards with no backlight voltage i came across a Chinese schematic fragment with a Haier logo in the top corner
it nearly perfectly matches this tv board down to the component designators
thought i'd post it here as there is little info out there on these all in one boards and obviously no schematics from insignia... -
Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this... -
Had one of these come in for repair with a blown battery and a WiFi issue, battery has been replaced with genuine battery (twice) and won't take a charge works fine on AC, WiFi issue gone away.
