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

I have a Insignia NS-L32Q-10A that will not power on. Now power on light or standby. I have replaced the power supply already. All caps look good and fuses check OK. What next???

ok, when you plug in the set, does the power light come on? Assuming you ordered a power supply in good working order, you may very well have a faulty main board. The power supply produces standby power that the main board uses to power the standby/power on light. Your main board also uses the standby power to provide the "ON" signal to turn on the rest of the power supply.

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.

27'' LCD panel compatability

Both power supplies are supplying the same voltages to the circuits but in order to use the one from the NS-27LCD 27" you will need to change the wiring configurations to make it work for the LCT2715..
I could repair the power supply from the LCT2715 for under $90.00 including parts, labor and shipping it back to you.
Let me know if you require further assistance.
