VUEALLPT 039

02/18/2014 8:29 PM

Good evening, please give me additional information about the ic called VUELLPT039.

It is a part of the tuner pcb of my radio from panasonic model SA-AKX52. I have the schematic of this radio but there is no information about this circuit. There is a little quarz oscillator beside this ic and it is not oscillating. I could replace the quarz oscillator but there is no frequency to read on it.

Thank you

I would contact Panasonic, this might be a proprietary chip...but it might be easier to just replace the unit....

Hi Randall, this is the chip. Thank you. How did you find it?

I found an used tuner pcb in repair store and installed in my radio. It is working again.

Thanks to all who posted comments.
