I am trying to source a replacement IC chip. It is used as the control element in a switching power supply ckt. for a flat screen TV. Part numbers I have are QSCA0S0MS012 or Mip2f30msscf Dip7-a1. As the second P/N indicates, it is a dual inline package with 7 pins as opposed to the traditional 8 pin conf. I have not been able to find a source or to cross reference it to a compatible IC. Can someone please assist in finding where I can purchase one of these chips. Thank you, Don

This sounds like a proprietary part. Digikey doesn't have it. Contact the manufacturer of the TV.

SOURCE: tv LCD RCA model L32WD22 what ic replacement can I use?

servicios,
Close the the unit up as you had before opening. Take the unit to a service centre and have them fix it. They don't have manuals to repair so, when they say, "We can't fix this" you take the work order and call1877-297-8391 and they will get you a new tv

Vizio lcd tv will not turn on but the


This is a very common issue with this model TV. The problem is caused by the power supply controller chip. This is a small 3 pin chip on the video logic board. When this chip fails the TV video board never gets the signal to turn on and display a picture. Here is a picture of the video controller board from the TV with the power supply controller chip circled, and here is a link to order the IC chip. Open the back of the TV and look at the little chip, you should be able to see that it is burnt. Replacing the chip should bring the TV back to life.

It looks like an IC has failed on your TV.
The IC is the vertical amplifier and needs to be replace to restore the functionality of your TV.

LG 42lc2d found u502 in power supply blown up.


You won't find a part number for this ic. These boards were made to be replaced as one piece. A new board should do the trick. If you can try to check for a short to ground. Most of the plugs on the board have voltages labeled. If there is a dead short you will see it with an ohm meter.

Same problem with mine


Based on what you have described, you have lost the power supply or main board. Unplug unit, carefully lay it of the front side, pull about 10-20 screws out of the back, look at the electronic boards, if you know what caps are, run your finger across the top of the caps,if they are swelled up, then that board is bad. Those boards go for 150.00 to 500.00 each.
