Re: VIZIO VX37L will not scan Digital channels or respond to up/dn channel changes
Is anyone else able to see the pictures and LDO readings?

Re: VIZIO VX37L will not scan Digital channels or respond to up/dn channel changes
Here are the pics and the data. I noted on the LDS table when there was a resistor near the Adj pin on the regulator. I also noted on U10 where the Adj voltage was Zero on this main board and others I saw had a value of .33 for example.
I appreciate the help,
Best regards,

I can supply a picture of the mainboard later this evening.
Is there a list of the regulators by reference designator for the devices on the Mainboard?...Leave a comment:

I've removed the mainboard and I'm looking for an obvious problem and haven't see one yet. Perhaps I can get my hands on a known good mainboard P/N: 3637-0012-0150(3c), and install it to see if the problem goes away. I've been reading various post and there are some with similar issues of not being able to scan digital channels.Leave a comment:

Hello aaronwt6,
Were you able to accquire a schematic for the main board of the VX37L while you were repairing one not too long ago?

Budm,
This TV has only one F connector and it is used for both the Analogue and Digital signals.
tom66,
Thanks for the input, would you be able to provide your best guess where a potentially faulty 1.2V regulator on the main board might be?
Thanks for your help guys,Leave a comment:

When I was trying to scan the channels the TV was connected to my TW Digital Cable.Leave a comment:

VIZIO VX37L will not scan Digital channels or respond to up/dn channel changes
Hello,
I recently acquired the subject TV at the swap meet for $20. It would turn on and then off. After reading similar posts & threads I checked out the PS and its working as advertized. I then read about the possibility of the TV being turned of last while using the PC input. I connected my laptop to the TV and then turned it on and it worked. I then changed the input to cable and attempted to perform a channel scan. The analogue channels scanned ok and when it finished I expected it the digital channels next.
However, the digital channel scan would not start.... -
