Sorry Donna, Any thing that i would tell you to try, you would have to understand the lingo and the theroy in electronics. A TV set is no where to be to experiment with as they hold alot of HI voltage ,even when they are unplugged. If the setd over5 years old, Maybe its time for you to thinkl about buying a new one. Good Luck

No longer has picture - voice still working - can it be fixed or is it worth fixing?


Not knowing brand and model number most of these sets have a 4-5 year life and parts for a set of this age may not be available.

The risk in repairing a set this old is it may just fail again and again.

Black screen with sound


My 47" LCD Smart T.V. was working fine last night. I got up this morning and I have sound but no picture. The VIZIO icon lights up as usual but I get no picture, only sound. From the time I turned it on, nothing appeared on the screen. I have already tried unplugging it for a while and still nothing.

Black and white only


Well - it's fixed - but no thanks to anything I did.  It's just all of a sudden working fine again.  I tried three different dvd's the other night, and all were black and white.  But last night the same dvd's were back to colour.  Who knows?
But thanks for asking.

Viewsonic problem


Have you checked the SCART leads?
Usually seems to be the cause of this kind of thing.

HDMI quit working I use this tv for a PC monitor, HD satellite viewing, and XBOX 360. I was having intermittent problems with the HDMI audio bleeding in to the other inputs. Sometimes if for instance I turned on the PC, I could hear the audio from the HDMI output on the satellite receiver through the TV speakers. Other times, I might just hear a crackle in the audio when in PC mode. If I switched back and forth between HDMI and PC inputs a couple of times, both issues would go away. I tell this just as background to what happened next. Since I have my PC hooked to the VGA input on the TV, I have been forced to manually switch the HDMI input from the Satellite receiver to my XBOX 360. (Sorry, I was too cheap to buy the $100 switch). Anyway, I usuall make this switch hot (TV on, Satellite receiver on, but XBOX off. This system although a pain, was working until yesterday. I was watching HD satellite, when I decided to play XBOX. I switched the HDMI cable, but when I turned the XBOX on, it wouldn't start up. I immediately assumed my XBOX had crapped out , but when I switche the HDMI cable back to the satellite, the TV would not recognize the signal. I have since tried the XBOX and satellite on another tv with HDMI, and both still work fine. I am thinking that some sort of switch in the tv has gone out, but I don't know. Should I just junk this TV for a new 1080P? My problem with doing that is that I use PIP with the PC on one side, and HDMI on the other. This tv does that, but I can't find another tv that does.
