Question about Panasonic TH-50PHD7UY 50 in. HD-Ready Plasma Television

3 Answers

New TV - no picture at all

I'm installing my father-in-law's TV. We've checked that the hook up is correct, gotten the right adapters, but still have no picture at all on the TV - not even white noise. Just blankness and a buzzing sound. The TV is a Panasonic Plasma flat screen, model #TH-37PH9UK. We have the cable box hooked directly into the TV using the red and white audio cables, and an S video cable (we've also tried to use a Coax, and the red, white and yellow all together - still the same problem.) Panasonic customer support is now closed. Please help!!! Thanks, Brenna

Make sure the cable box is on. If the TV has never been hooked up before, it doesn't know which input it is supposed to display until it is told or it finds out,
If you turn the TV off and back on ,when you change the wiring it will search for an input signal. If you don't it will stay where it is

Try pressing input on your remote and make sure the source is selected to what you have it plagged in. For example cable box plugged into hdmi1 set input to hdmi 1. Also can you access tv setup at all? If not your tv might be bad to begin with.

SOURCE: Panasonic TH-46PZ85U Plasma TV

Symptom:
TV shuts off unless all the input (phono and HDMI) cables are disconnected. The
symptom may be intermittent.
Cause:
There is an abnormal AC voltage entering the TV from one of the input cables or AC
outlet.
Remedy:
Follow the Testing procedure to determine if there is a problem external to the product.

Concept
Constant symptom
If the TV no longer shuts off when all input cables are disconnected, then one of the
input cables is introducing abnormal voltages into the TV. Panasonic Plasma TV sets
have 3 wire AC plugs.
As a result, abnormal voltages introduced into this TV will cause the TV to shut off for
protection.
Intermittent symptom
If the abnormal input voltage is borderline (marginal), the TV shut off symptom may be
intermittent. However the cause may still be detectable with a voltmeter.
Protection Proof:
Release the protect mode - the TV has to be unplugged to reset this protection circuit.

Threats from the HDMI input:
Excessive voltage from an HDMI cable connected product will activate the Plasma TV’s
protection circuitry. Placing an isolating / buffering connector (sometimes called a voltage
conditioner) between the TV and the HDMI input cable often solves the problem.
Testing -
Unplug all the HDMI inputs from the TV. Turn on the TV. Plug in the HDMI inputs one at a
time. The cable that causes the TV to enter the protection state is connected to the product
that has the excessive voltage (and signal). Avoid connecting this product until an isolating
connector is found.

SOURCE: My Panasonic Viera 50" 1080i

The Panasonic doesn't detect the presence of the signal on the antenna input so it just skips it. shut down the player and turn the cable box on before attempting to switch sources.
But why aren't you using the Composite RCA connection on the cable box ? Not only you would get a much better image but the tv would detect that change in the AV source and should switch by itself. If it doesn't then the control processor is faulty and the entire mainboard will will have to be replaced

Hi. I've just hooked up my 3500S to a new Samsung


Hi
  • Make sure your SCART cable is fully cabled...for IN and OUT connections..
some SCART plugs works one way..I recommend to replace it with another one at least for testing..
  • Second option,buy an SCART to RCA/S-video adapter and use that one for "s" connection..
here is an example of SCART TO COMPONENT & S-VIDEO adapter on the URL below..

Sound is not working. everything is plugged in right. got the tv from my father-in-law who always had it hooked up to a receiver box. now we have it and dont have a receiver box and are unable to get any...


it sounds like the internal speakers are just off. you should be able to navigate the menu and find where to turn the speakers back on. i have my tv set up with a surround sound system and turned the internal tv speakers off. should be in the sound settings or with a picturre of a speaker.
