Question about Zenith B27A76R 27" TV
I have a Zenith B27A76R console television I purchased new in February 2005. Over the past three months, I've had an incredible amount of problems with black images on the screen. These can range from a black rectangle to a long thin black line to having nearly all of the television screen turning black. These instances last anywhere from 1 to 3 seconds. The picture always comes back fine. These problems can occur anywhere from once every 15-20 minutes, once every few minutes or hardly at all during the day. We have cable on our television and we have a VCR and DVD player patched into the television. This problem occurs no matter if we're watching cable TV or if we're watching a DVD. I've called the local company where we purchased the television. He told me to check the cation settings which I did, but I think these black images are not related to captioning. Please advise if you have any ideas. Thank you! Paul in Wichita, Kansas.
Your problem is in the horizontal sweep and its called blanking. it happens on mostly zeniths sets as Ive seen it a few times and the only waty to fix it is to replace the entire chassis as there are no parts for zenith available just the module as a complete assy. Basicly, The blanking is suppose to only blank the top and the bottom of the fields of the screen that you don't see but it misfires and causes all sorts of lines, squares, and boxes on the screen. When i first was told of this problem i thought the same exact thing?? About the closed caption but the set came into the shop and didnt do the problem. I thought the customer was seeing things. Then finally on night late I CAME BACK TO THE SHOP TURNED ON THE BENCH AND THERE IT WAS!!! i SAW IT WITH MY OWN EYES!! I replace the Module and all was good. Thge repair was about 175 bucks. Good Luck in your repair. Oh this should not be attemted by a handi person, as there is dangerous high voltage inside these sets.
