Vizio GV47LF Television - Answered Questions & Fixed issues


I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

Hi Anon,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.

Chromecase is a USB 'stick' type device with a USB interface. The RGB port is a video only port on the TV and not compatible with USB signal levels or the physical plug type.

The ABL circuit to main logic board should be checked. It is a skilled work. In most cased, this board might need replacement. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

A very common problem w/ this set is a fuse that will open, that is located on the main board(the board w/ the tuner on it). This is a very small surface mounted fuse, it's white in color, and located at the upper right hand corner of the board, if looking at it from the back of the set. The location number is F3 and the fuse is 1.5 amp. I have seen many of these. I would definately start there.

If the problem is same with different input devices and you have ensured there are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

Same problem on our GV47L-FHDTV10A was caused by a VERY small fuse on the mainboard. On top right of mainboard there are 3 small fuses they are white with gold ends. The left one (f1) is 1.5 amp we just soldered one from radio shack on it to bypass the fuse and it is working like a champ now.
