After a lightening strike hit our house, our Panasonic Viera powers on but does not have a picture or volume. The best buy geek squad set the TV up but did not plug into a surge protector. Is the TV done?

I would say there is a good chance that the power board has fried , or some rectifiers on the power circuit have gone, i would check the mosfets for damage too. I would try a working power board in it to see if any life is shown before writing it off

Panasonic viera tv model #TC-L42U25 Had a lightning strike tv went off. Hit power button it comes on no picture or sound then turns off and flashes code 12. Is there any hope? Thanks,Patrick


Most likely your A board, which is the main circuit board. Best to call a technician for that. This may help.

Tip

BEST BUY GEEK SQUAD ROUND-UP


I can confirm that this level of incompetence is quite common. It is Best Buy's standpoint that Geek Squad is an extension of their sales strategies, thus their hiring practices reflect that standpoint. Many Geek Squad "Agents" are hired or transfered to Geek Squad based upon their merits as sales people, NOT technicians. This strategy, combined with the pathetically low pay level (which any certified or experienced technician would laugh at) results in untrained staff programmed to follow certain sales strategies. In my experience, many of my fellow employees were on the same technical level as the customers across the counter seeking support.

Best Buy did settle with Winternals / Sisinternals and integrated many of their tools into Geeks Squad's authorized repair disk (Much of which is purely automated). At some level, Best Buy has internally recognized that their Geek Squad staff is mostly unqualified and have catered their corporate licensed / developed software to reflect the situation. This not only showed Geek Squad's incompetency (again) but also shows how news media is more interested in scaring you than actually helping you. It's good that the big chains got this bit of negative press on a local station but you should also applaud the store that did it for free - at least post their name and address and show an interview with the owner or clerk.

Mom and pop shops are usually run by people that are hobbyists first and business-folk second. Whenever someone at my company asks for personal computer help that I don't care to deal with I send them to a small shop in our town - one with Windows 3.1, Windows 95, Netscape Navigator and Word Perfect stickers are mostly-faded on the window. I know they'll be treated honestly and fairly. No charge just to examine a computer to add onto the actual repair.

It's sad how many people/companies are more interested in making the most money from a problem instead of trying to solve it fairly.
and LASTLY "1st thing that video is at least 8 years old I remember seeing it when I was young in highschool."
Perhaps you are thinking of the PC World investigation of major retail computer service departments? I remember reading it long ago:
http://www.pcworld.com/article/3764-6/pc_repair_ripoff.html
The article is from Mid 1998. A damaged IDE cable was part of the problems on their test PCs.

From the article:
"Of 55 problems tested across 20 stores, a total of 30 were misdiagnosed, ignored, or went otherwise unfixed. Best Buy and Computer City each missed on 9 of 15 tries."

THE REAPIR WE WERE TALKING ABOUT WAS A 10 TO 20 DOLLAR FIX :()

AND


A confidential settlement has ended litigation initiated by Winternals over copyright infringement regarding Geek Squad's use of its ERD Commander software.

The lawsuit should end following a July 7th motion from Winternals lawyer David Weaver, who cited a settlement agreement reached between the company and Best Buy, which owns Geek Squad.

Instead of a lengthy lawsuit, Winternals now has a three-year agreement in place with Best Buy. This will permit its Geek Squad of tech assistance personnel to lawfully use licensed programs from Winternals and Sysinternals. This includes the ERD Commander system recovery tool.

The problems for Best Buy and Geek Squad started in February 2006. Winternals had conducted training sessions for Geek Squad employees, as part of its negotiations with Best Buy to license software for its 12,000 Geek Squad workers.

Then the negotiations ended abruptly. Coupled with the admission from employees of Geek Squad and Best Buy that they had been using unlicensed copies of ERD Commander, Winternals began to investigate.

They set up systems needing repair in multiple locations, and put calls in to Geek Squad for assistance. Geek Squad staffers either used unlicensed copies of ERD Commander, or had them in their possession.

In April 2006, Winternals sued in US District Court in western Texas for copyright infringement, circumvention of copyright protections systems, and misappropriation of trade secrets.

I have an Insignia 50inch Flat with no picture or sound just went black


Most likely the power supply board or the fuse. Insignia is really an LG TV. It is Best Buy's house brand. The Geek squad can fix it.

Panasonic Viera TH-50PX80A. After lighting strike, inputs do not work.


The set MAY have a hard reset but you would have to call Panasonic to find out.

What happens with lightening strikes is RF gets into the set in two ways--via the power cord (usually a dead set is the result) and via the coax or cable fitting.

It sounds like it was the latter--it may have confused the microprocessor in the set(input issues) so unplugging set and or a box if used (receiver unit also!) may or may not help.

Surge protectors rarely operate quickly enough to stop this and even if the cable feed is protected stray RF can get past that also.

try my suggestions and then call Panasonic.

The best way to set up a TV such as yours without a calibration device is to get a high definition picture of someone's face on the screen and adjust the color, brightness and contrast until the face looks as life like as possible.

My screen is cracked it will not show a picture or volume can i get this fixed or do i just need to buy another tv?


You could potentially get it fixed, but depending on the size of the TV it might be more cost effective to get a new TV. Dynex is a "store brand" that usually has lower quality components in it. You could check with the Best Buy Geek Squad on what the cost would be to repair the screen. That's also assuming that it is only the screen that is broken.

That happened to my TV and it ended up being that the screen overheated and blew. Best Buy Geek Squad was going to order a new screen but replaced the TV instead.
