Panasonic TH - Popular Questions, Answers, Tips & Manuals

Not totally sure what your asking but I think your saying your LED lamps aren't working, if that's the case replace them

I'd check your Panasonic user's manual, usually, there is a list of codes for "other" devices. There may also be a way to do an automatic upload of the Toshiba device's code if it is on and the right button on the Panasonic remote is pushed.

You can often find the digital channel numbers for your local stations in a guide like http://www.titantv.com/ or https://tvschedule.zap2it.com/?aid=gapzap . Alternately, check if the local stations websites offer a link to their schedule. This will usually list the channel/channel digital identity. Another source for the digital channel numbers are the antenna choice/position/direction guides. Look at http://www.antennaweb.org or http://www.tvfool.com . Tvfool.com gives the direction and signal strength for all channel transmitters in your general area. Antennaweb.org is much more conservative and will only give the strongest stations in your area. That conservative list assumes an external antenna and clear path between the transmitter and your antenna. In my area, the analog channel 7 became digital channel 7-1 . However, the channels 12 and 16 now transmit at 43-1 and 46-1 . However, after letting the TV do the auto-search, they are 12-1 and 16-1 when I type in the channel numbers on my remote. I hope this helps. I might be able to provide a list of your local digital channels if you add a comment with your general location. Cindy Wells

Can you see the TV's option menu?

Ive got bad news for you, about 90% of the time black horizontal lines are caused by the panel failing, your going to need a new TV. You can try replacing the timing board but the chances of it fixing it are slim..

First step check fuses then if they are bad replace them, also check the voltages on the various test points on the power board

Replace the remote first.

A guess would be you have some LED's in the panel that are going bad and its drawing to much current

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here.
