Question about Televison & Video

2 Answers

Vizio VO47LFHDTV10A-B No Picture, No Sound I have my TV connected through a Sony A/V receiver for sound and HDMI switching. I was watching TV and switched to my computer. When I switched back it looked like the 2 video streams were on top of each other. Right after that the TV picture and sound went out. I'm hoping that it is a fuse or or power supply problem. I have a second TV of the exact model that has a hole in the screen that I can use as parts. Can anyone help? Thanks Wayne

Have a VIZIO 47" flat screen led tv, VO47LFHDTV10A,the screen went black, but still had audio, I replaced the power supply, with a refurbished unit from VIZPARTS, still screen is black and now no audio, the voltage seems to be correct on the power supply output, I have 24v, 12v, and 5v, I also found caps on the master and slave inverters blown (crowned and leaking) 680uf 35v, I have ordered these capasitors, which might fix the black screen but finding it hard to understand why no audio after replacing the power supply, can anyone Help?

Please find above your user and below is your service and repair manual, use this to troubleshoot and hopefully repair your unit.
it is nearly always my professional opinion that one should always get a "Quote" from the manufacturers recommended service center, Toshiba in your case, please contact a local or head office and ask for a referral to an Authorised service center. I cannot stress how important that last point is. It is even worth the cost of shipping. You see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.

The main board is having an issue the AV inputs will eventually fail as well the HDMI are first to fail. Replacing the main board should solve the issue. You can get the replacement main board from www.tvcircuitboards.com

I have this receiver hooked up to a Vizio LED tv and a Vizio Blue Ray using HDMI cables. The surround sound works from the speakers while watching a dvd (HDMI -1 connection) but I have no surround sound...


AV cables don't pass surround sound through, they are pretty much just left and right stereo. You need to turn pro logic on on the reciever to "pretend" to play surround. The better option of course would be to use a digital signal like another HDMI cable or digital optical audio from the cable box, if thats what your using.

No play back from HDTV to threater system


Do you have set-top-box or antenna-cable directly to TV?
You have connected TV with received via HDMI, but that won't work in this direction - TV has HDMI INput only, not output.
You can use HDMI to connect HDMI-out on DVD player for example to HDMI-in on receiver and HDMI-out of receiver to HDMI-in on TV.
But to get sound from TV to the receiver, use spdif optical or coax cable if TV supports that - this way you will get surround sound.
But also your connection via analog white/red RCA plugs should work, but only for stereo sound.
