I just purchased this tv and have the following problems (I'm also
thinking about taking this scumbag on-line retailer to court for selling me this defected product): 1. When the tv is first turned on, no picture or sound for 3-5 minutes 2. Then, sound comes on and picture starts to flash (on and off) on the screen 3. Picture finally stable a little after another 3 minutes but still goes black randomly for a very brief moment What could be the problem? I'd appreciate it if anyone here could help. Thanks. |

If this is a new set, you should have a warranty. If not, it would have to
be properly serviced. The fault can be in the power supply, because of the fact that both the picture and sound are effected. Also, if the display is flickering, the backplane lamp, and or the power supply for the lamp may also be defective. These units are serviced at the modular level by the manufacture. If you can determine the exact modules to replace, you may get it running if no factory level adjustments are needed. It is best to have the proper facilities to service these sets, so that there is no guess work, and it can be properly adjusted if necessary. I always advise my friends to not buy any of these sets used. From my experience and from what I have seen, most of this level of electronic equipment is sold as used, because someone had a problem with it, or for some reason they were not happy with it. These sets are very expensive to service. They are also not as reliable as the older CRT type sets, therefore a service contract is a wise decision. The above is my personal view, from my own experience from working in the service business. -- Jerry G. ====== wrote in message oups.com...

Jerry,
Thanks for your accessment. One thing I didn't really make it clear was that when the picture flickers (goes completely black) randomly, the power seems to be OK (the green light at the bottom is always on). Could it be possible that the AVC unit is at fault but not the tv? Anyways, to whoever is reading this post and thinking about buying an LCD tv online, remember, DO NOT buy from DigitalGear!
