Question about Zenith B27A76R 27" TV

1 Answer

Black Shapes Encountered on TV Screen

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.

Re: Black Shapes Encountered on TV Screen

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.

If you lost the remote for a zenith television and want play a movie on an input, use the channel up/down buttons to navigate. Ususally if your on ch 2, press the down button. Line 1/2 will appear on a blackscreen if the device is off. Otherwise, I have had great success using a GE universal remote with my Zenith tv/vcr combo unit. (by the way, I work for the technical support department for my city's local cable company)

The short answer is no. You will not need a converter box. This set contains the ATSC tuner required for the new over-air signals.

Pip for my iQB36B44w

The PIP may only work with an external tuner or source (VCR, DVD, CATV box, etc) If your TV doesnt say "dual tuner" then you need an external source for the PIP (Use a VCR and its tuner for instance)
