TV problem
Hi My Panasonic TV model number TX-W28R4DP has just gone wrong. This happened suddenly without warning as the TV was switched on. The screen has scrolled up so that there is a black bar at the bottom and shimmering black lines through the rest of the picture, see picture below. http://i18.photobucket.com/albums/b1...erseyes/tv.jpg Does anyone have any advice please? Thanks in advance. Kris |

TV problem
Appears to be a problem in the vertical frame deflection circuitry. Possibly
the output ic, associated capacitors and other components. Post actual diagnostics you have done or off it to a qualified service facility. "Every Strangers Eyes" wrote in message ...

TV problem
Not done any diagnostics as I'm a complete novice when it comes to TV's.
I guess it'll have to be scrapped as the cost of repairs will probably out weigh the cost of a new TV. Thanks for the help though.

This is probably a rather minor and easily repaired problem. --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name AND either lasers or electronics is included in the subject line.
