My VIZIO vx32L/hdtv10a remote only lets me change channels. No volume up/down or power on/off function either

u have a failed board. new board costs more than the tv

I had a similar problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. I didnt hear an arcing sound though. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound. I would check the ceramic fuse first on the board that gets power from the plug.

HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine.I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

I would say the high-voltage transformer which acts like a power supply itself is bad. Noth the board!

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

I have the exact same problem, let me know what you find. This the 1st I've tried the DTV, has your DTV ever worked.

why should i tell you (fixYa) how i fixed the problem for free? You wanted to charge me for your info so i think it's only fair that i charge you for mines. I did figure out and solved the problem.

there a problem on power side.. chage the ic and the resistor going to ic and check also the signal diode.

sound like the inverter circuit board problem. check & replace back same part# inverter circuit board. hopefully could help!!
