Open Question

Vizio Gv42lf will not tune digital channels

I have a vizio gv42lf (about 2 1/2 years old) and it will not channel up or down from the remote. I go the the cable setup menu and scan for channel, and it finds 81 analog channels but does not move the digital channel bar graph. I have to cancel out of the channel scan. It still works great for analog channels, A/V inputs, RGB inputs and HDMI inputs.

Don't buy it. VIZIO is not standing by their products.

My GV42L had issues from the ssart and now it shows No Signal and shuts of in 2-3 seconds. I read many similar issues on this site with VIZIO.

Well you need to do some troubleshooting first. No pictures/No sound can be caused by failed 12v/24v power supply section due to bad caps, or it is not getting the PS_ON signal from the main board, or the inverter boards have shorted circuits that cause the 12v/24v power supply to be in the safety shutdown mode.

This can be due to possible AC factors in the power supply and is due to poor regulation. So check for faulty, leaked or weak capacitors, if the fault clears up on heat then thisis for sure. If so you can simulate heat using a hair dryer to pinpoint the area of fault and confirm. Also placing a capacitor of similar value in parallel to the suspected capacitor will confirm as the fault changes.
Attempt only if equipped.

Older person cannot handle two remotes


You can program most satelite remotes to work on any device. Most are universal. If not, I suggest purchasing a universal remote. You can view remote codes online to program your device to your remote. New ones come with instrucions and codes.
