Should I be concerned?
I have a Toshiba TW40X81 HD Set, which is now 2 years old (I purchased it from Tweeters with a 3 year extended warranty). Over the past few months it has started acting strangely if there is a bright blue background and the camera pans in any direction the blue color flashes (blinks)
I have run both AVIA and Video Essentials and have adjusted my set but it still has this problem.
There have been a few other problems for example on the standard NTSC color bars in both AVIA and Video Essentials on the blue bar on the right there is an “S” curve with the color to the left of it. Also the over scan seems to be off as on the Superbowl I could not see the score bar (except for a tine bit) which was shown on the top of the screen.
Because of my extended warranty I decided to call Tweeters and have my TV looked at and I also requested my free yearly cleaning.
Yesterday 2 guys came over my house and asked me what the problem was, so I showed them and they both agreed there was a problem, in fact one of the guys noticed another convergence problem on the left side of the screen that I didn’t notice.
(Here is the part where I started getting nervous)
I told them that I requested my annual cleaning and they said no problem, the one tech instructed the other to go behind the set and clean the set. The 2nd tech grabbed what looked like a dirty orange shammie and asked my wife for some paper towels. He thank began rubbing down the lenses of the guys on the set with them (I was unsure if he used the paper towels or the shammie) He then put the cover back on the set and said he was done. (He didn’t clean the mirrors or anything else in the set)
The first tech was talking how besides the blue flashing problem that he thought my set has a convergence problem. So next he asked me how to get in to the menus so that he could check the convergence. I showed him how to get into the 9 point consumer convergence screen and all the convergence was fine. I asked him if the convergence screen in the service menu would be better and was told that he did not think that the Toshibas has a convergence screen in their service menus. (Being a member of AVSforum.com and HomeTheaterforum.com I KNOW there is a 64 point convergence screen in the service menu.) He said when he got back to the shop he would check Toshibas website to see what was in the service menu.
Shouldn’t a television technician know how to access these things?
He then stated now what the problem with my set appears to be a main board problem, and that the voltage from the main board was not being outputted correctly which is causing my problems with the blue flashing and the S curve on the NTSC color bars. While this does sound like a valid idea of what is wrong, he never took my set apart or went into the service menus to see if anything was wrong.
I am sure a main board is probably a very expensive item to replace. I would hate to see these guys put a new one in an not have it fix the problem, and even worse I would hate to have these guys make my sets performance decline more. I am already worried that they probably already scratched my lenses by using that dirty towel or a paper towel.
What should I do? I do know that Tweeters subcontract these service people. I have no problem with Tweeters or with anyone at Tweeters, they have always been a good company to do business with.
These guys have probably ordered the main board already, should I let them come in and see if they can fix it? Don’t get me wrong they were nice guys, however they did not seem to have any clue on how to properly service my set.
