Insignia TV Powersupply

Hey, I am a student and I need to replace my power supply in my parents Insignia tv. I was wondering where you order the power supplies from and roughly how much they cost. Thanks in advance.

    I am fairly well with electronics and such for repairing, reading schematics and building them once I am given a schematic. However, I am not very good a diagnosing problems. I am wondering if you know what the problem with the power supply usually is.

    The TV will turn on occasionally but will power off after sometime (a different amount of time always) also sometimes the when it is plugged in and the main power is on the light won't be red and definitely won't turn blue once the other power button is pressed. When I read voltages it's reading 121.8 at the input and around 85 at the power supply. Do you know other places I should test or if it is just a component on the power supply that fails and if that is case there is a good chance I have that component around here (where I work) and can replaces just that. Thank you again in advance.

    I would suggest to visually inspect the electrolytic capacitors for bulging and leaky conditions or if you have a capacitance meter to remove them and test them outside the circuitry. The capacitors failure is very common on LCDs power supplies older then 12-18 months.

Insignia tv, will not power on. no lights are on

Try using a different room. The sockets will probably be on a different circuit. If that doesn't work, it sounds like a power supply problem on the TV. You'll need to replace the part. Unfortunately, it's usually cheaper to buy a new Insignia tv than getting the power supply replaced. TV technicians are expensive

Insignia quit working after storm

Check the fuses on the power supply board first. They usually blow when you get a power surge. You may be able to replace them and get the TV running for a few dollars. If the fuses are good then the power supply board will be the issue. The main board should not be damaged because the surge has to go through the power supply board first.

RCA TV Model F32444 Will not power on

The noise you are hearing is probably the degauss (it demagnetises the screen every startup). The most likely problem is the power supply. Do a replacement of all the caps on the powersupply board and it will likely fix your problem. Because it still has power to the degauss coils it hasn't blown the fuse. Power supply not starting like that is usually caused by a small electrolytic capacitor near the heatsink on the mains side of the powersupply. They can be replaced for about 10 cents.
Hope this helps
