TV repair help guidance sought on a Mitsubishi VS-45VA1
TV rear projection TV
Manufacturer: Mitsubishi Model: VS-45VA1 Model year: 1993 Overall Dimensions: 40w x 50h x 21d Screen: 36w x 27h,... 46" diagonally What's known good: Each of the three projectors (red, green, blue) are fully operable and in focus. Audio is unaffected and functions well. The symptom is akin to the effect viewed as a partial signal block from HBO in the late 1970's. where the picture shows up on screen with a wavy horizontal flickering side to side motion. Depending upon the input signal strength, the horizontal wavering strengthens as the signal gets stronger. When using an antenna ( tested both antenna 1 input and antenna 2 input), Channel 8 can receive marginal reception as the the channel is broadcasted from 45 miles away. Some snow (weak signal indication), a little spotty (microwave background distortion), but very few wavering lines as compared to viewing a VCR/DVD input. All other channels are too distant to receive (I have not activated cable TV yet). On channels without formatted broadcasted signal received ( snow microwaves only), there is no indication of wavering lines at all, and no indication of a malfunction. With the input coming from either video 1 or video 2 (front and back tested) having an 8mm camera connected to the TV, and active, and panning the lense to the kitchen (not so bright), horizontal distortion exists. Then when panning the 8mm camera to view through the window outside in the bright sunlight, the distortion intensifies and the video output on the TV screen becomes unrecognizable. Without any signal input showing up on the screen, in the case of the full screen TV setup menus, all text colors and text are sharp and background color is picture prefect. This is also the case when the vhs is connected and the stop button is pressed) with a tape active but not playing. The output is the pretty blue blank screen (normal attribute in this scenario) and the display statistics (date, time, position counter) appear in picture perfectly clear white lettering. I am fully capable of dismantling and replacing any of the circuitry board components. If you have any TV experiences / thoughts to share (however trivial they may appear), I'd appreciate your input. Thanks, Ken |

Thank you once again for your kind words. If you know the parts I need, your continued input is apperciated. Thanks, Ken "Michael A.

Thank You, Ken What an attitude for someone looking for help, and too ignorant to use the right newsgroups. news:sci.electronics.components was created to help designers track down OEM parts, not to fix TV sets. BTW, the words are 'ENCOURAGE' and 'KNOWLEDGEABLE', if you're so hell bent on 'knowledgeable persons'. As far as 'knowledgeable', I started working in TV repair 43 years ago, and worked in electronics repair & manufacturing until a few years ago. I was also a Radio & TV Broadcast Engineer Keep up the arrogant attitude, and no one will bother to answer you. -- http://improve-usenet.org/index.html aioe.org, Goggle Groups, and Web TV users must request to be white listed, or I will not see your messages.

I am viewing it in sci.electronics.repair and it seems appropriate for that newsgroup. |
