Vizio TV Freezes when connected to a Network Issue

After having my brand new Vizio have freezing issues from the day that I brought it home and 3 exchanges later, I finally have a resolution to a problem that i'm sure is common, but can't find a single solution and not even a mention of this from Visio themselves which is strange. My tv would work flawless, until I wanted to connect to a network via wif-fi or wired. As soon as it would connect everything would freeze up.. No response from the remote or the actual buttons on the side of the tv..a million power resets won't fix this so don't waste your time going thru those frustrating steps. Trust me, I exchanged my tv 3 times over a course of 3 months through Visio (all very smooth and hassel free experiences I might add) but they just couldn't find the right answer and I was frustrated and on the verge of returning it. Then I reached tier 3 tech support at visio and they got down to the solution together and if you are having this issue here is your solution and should solve your freezing problem so you can enjoy an otherwise fantastic tv. When connecting to a network either using wi-fi or ethernet make sure that any computers or other devices that may be using a DLAN network or DNLA software is disabled or turned off. They cause a conflict with the tv's network settings and causes it to freeze. In my particular case I am on a Mac and had a DLAN network running on a program called TVMOBili, once i turned it off and no other devices are running on DNLA everything works perfect. Hope this helpful and saves someone from going through the same frustration as I did.

SOURCE: SV470XVT Vizio picture freezes

Hello, This seems more like an interface problem then a board issue. Which interface are you using Component Video, HDMI or , RF(F Connector)? If you are using the RF (F Connector) there might be a problem in the tuner including the RF and IF sections on the circuit board. If you are using HDMI there might be a problem in the HDMI Integrated Circuit If you are using componente video the there might be a problem in the video circuits connected to the RCA jacks of the Component video input. If I were you I would have the take the TV back to the shop and have these items checked out, because board swapping is not the proper thing to do. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

Hi, Mary with Dish Network Customer Service. Since the DVR is the only thing having the freezing issue, it sounds like it maybe a hard drive issue. I would recommend resetting the receiver. Unplug it from the power supply for 10 seconds and then let the receiver reboot itself. If you are still having this issue, I would recommend calling Dish Network and we will need to replace the receiver. Hard Drive issues do not resolve themselves and only get worse over time. Please let me know if I can be of further assistance.

You must be talking about the 522 DVR. If so then there could be issues with your hard drive or a cableing issue. be sure to connect all sat in connections and if you conitune to have this issue call 1-800-333-3474 for tech support as your issue could take extensive troubleshooting. More than likely your will get a replacement DVR and if you still have the same issue then a tech will need to come out to check cableing, ground and lnb's on your dish.

VIZIO VS42LFHDTV10A Freeze Up


Just unplug the comcast and see how the tv works, if the TV works fine, then you will now the trouble is not your TV.

It is not likely to have the same issue in the new TV, just unplug everything and use a dvd to see how it handle it.

Printer FREEZES and prints blank pages


I DON'T THINK ITS THE PRINTER. THIS IS A SOFTWARE OR NETWORK ISSUE.

1 IT SOUNDS LIKE CORRUPTED FILES BEING SENT TO PRINTER, OFTEN PDFS. CLEARED ALL PRINT JOBS? ALSO AS400 PRINT QUEUE?
2 ALSO SOUNDS LIKE A VIRUS POSSIBLY "Adot.BAT". go online to housecall.com and do online virus scan.
3 OR, SOME OTHER CHANGE OR NEW DEVICE ON THE NETWORK MIGHT BE INTERFERING.

FIRST, TRY ISOLATING THE PRINTER FROM YOUR NETWORK. UNPLUG THE PRINTER FROM ALL DATA INPUTS AND RESTORE DEFAULTS. (LEFT OR RIGHT BUTTON TO SERVICE MENU, PUSH CHECK BUTTON, LEFT OR RIGHT TO RESTORE DEFAULTS, PUSH CHECK BUTTON).
IT SHOULD RESTART, THEN CALIBRATE. NEXT PRINT A CONFIGURATION PAGE FROM ITS MENUS, IF NOT TWO PAGES NET CARD IS DEAD.
IF OK SO FAR, TRY CONNECTING IT JUST TO A LAPTOP. USB ONLY THIS WAY, OR USE A NETWORK HUB, SEPARATE FROM YOUR NETWORK. INSTALL ANY OLD LASERJET DRIVER OR PRINTER ON THE LAPTOP JUST TO TEST IT.

IF ALL THIS WORKS, THE PRINTER IS FINE. BEFORE RECONNECTING THE PRINTER TO YOUR OFFICE COMPUTERS, FIX YOUR NETWORK & INTERNET OR VPN PROBLEMS.
THEN, DELETE ALL HP LASERJET PRINTERS & UNINSTALL ALL HP DRIVERS ON ALL NETWORKED COMPUTERS AND SERVER. (EXCEPT ZIPPED DOWNLOADED DRIVERS). START NEW HP PRINTER INSTALLATION COMPLETELY FROM ZERO. REINSTALL ONLY THE DRIVER YOU NEED. PCL5 IS RECOMMENDED.
