Question about Panasonic TC-26LX20 26 in. HD-Ready LCD Television

1 Answer

2005 Panasonic LCD TV Model# TC-26LX20

There is a black/gray, 1 inch thick horizontal line that runs from the middle of the right edge of screen almost to the left edge. It tapers to about 1/2 inch about the middle (or center) of the screen and continues on. Only not apparent when whatever is on that portion of the screen is very dark. I paid $1800 for this TV and I hope this is easily, inexpensively rectified. Cable company (RCN) recalled/replaced an old cable box a few months ago because of "universal" problems -- details of which I do not know. TV was on shelf above that and is now on shelf above much smaller, replacement cable box Shelf below that holds my Panasonic DVD/VCR (although a Samsung DVD/VCR use to be on that shelf.) Bottom shelf holds my wireless router (Linksys) box connected also by the cable company.

    I am having the same problem with my TV with the same model number. Dark lines that start at the right side and narrow to a point as they go left across the screen. The lines are mainly visible in dark scenes but it is getting more prominent. I'm assuming it is a problem with the back light but not sure. I was fishing around to see if someone had found out what this is but nothing yet.

    I purchased my TV Feb of 2005... noticed the same creeping dark "cloud" about a year and a half ago .. started on the right side 1/3 of the way down from the top. It has since stretched across the TV and now almost touches the left side. Paid $1500 for it .. recently decided to shop for a new TV as the prices have come down.. called Panasonic 877-958-4372 to inquire if there was any kind of known defect with this model. Though they were very nice they actually said "this is the 1st complaint of this type we have received and with all the sets manufactured it is expected that there will be a very small percentage with defects". Though this is a reality I was kinda shocked to get that kind of response - like "oh well, whatever"... I am now looking to buy a TV other than a Panasonic and will be putting this one out to the curb.

I am also having problems with the same year and model number panasonic, it is at the repair shop now. I think it is a lemon tv. won't buy panasonics anymore. Tried all the fixes recommended by panasonic. It happens after the tv is on for longer than 1/2 hour. It happens with dvds and different hook ups. my samsung is fine on all the same connections.

Lightning hit nearby now my Panasonic tc-l3232c has sound but no picture what could be the problem?

Two issues come to mind on LCD/LED TVs with a blank screen. First and foremost, unplug it from the power source for a few minutes, then plug it back in and power on to see if your problem has gone away. If not, then the easiest way to diagnose the problem is to power on your TV in a pitch black room (or drape a thick blanket over it and peek underneath at the screen while it's on)... we want to see if the backlights are working or not. If the screen looks like it's 'lit up' with a dark gray tint to it, then we have backlight and there is another problem. If no backlight, then your set has a bad backlight inverter. In either case, this will require parts replacement. Panasonic is very tight with who they will sell their parts to, unlike other manufacturers and usually require authorization from a technician before selling them.

I can very well understand how disappointing this is. But no company can ever do a free replacement for such causes. You need to have pest control in the house as the cockroaches can damage any electronic equipment from microwave oven to audio/video equipment in the house. If you do not do that, it will be Panasonic today and some other brand tomorrow.
