HD50LPW42 screen is black with antenna inputs


It sounds to me like you have a tuner issue, I have seen this before. If you have a good picture from other sources and they have the same antenna input, the tuner is suspect.

I hope that this helps you solve your issue.
Thanks

The picture went fuzzy (color alignment).


craighirman,

try going to the antenna input from the menu screen, then trying to do the auto focus, or manual focus. My Samsung won't let me do the auto focus unless I'm looking at the antenna for some strang reason.

What is your TV input connection? Are you using Antenna? Cable? Dish?

The Unusable Signal sounds like the TV is not getting a signal. Does your TV have a built in HD Tuner?

If you are using Antenna you might want to try setting up the connections and it should search for quality channels that you get good signal strength. If you are on channel 2 and there is no over the air channel 2 it may say "unusable signal".

Still won't work


Hi again,

This forum has much info re Mitsubishi PTVs. Nonetheless, an excerpt from there....
1.Set the Layer Switch at the top of the Mitsubishi Remote to TV.

2.Press and hold the POWER button, and while holding the power button enter 090.

3.Now the remote should function like this:

Power = Power On Discreet
Stop = Power Off Discreet
Pause = AV Reset

Pressing INPUT followed by:
PIP = DTV
1 = Input 1
2 = Input 2
3 = Input 3
4 = Input 4
5 = DVD / Component 1
6 = Component 2
SQV = Input STB
QV = Input VGA
PIP CH Up = Antenna A
PIP CH Down = Antenna B

4.When done, press and hold the POWER button and enter code 000 to return to the standard remote functions

No picture, sound OK...setup menu shows up, able to get picture in PIP


You will need to check the inputs on the television. You more than likely have a bad video in signal. This can be a bad cable or a loose connection either at the input of your television or at the output from your receiver, (cable or satellite). First, try wiggling the cable and then try replacing it. This should fix the problem. If not, your signal may be routed through a stereo or other switching device?

Picture is snowy on every channel. I hooked up my playstation and set it to the correct channel but the screen display is the same. I tried using the menu and the menu comes up just fine. The menu goes on...


If one tv looks good and another one dosent look good or operate correctly then we know for sure that the problem is not the antenna. Now the menu comes up ok because the menu is injected after the tuner into the video curcuit from a osd or microprocessor. sounds like you could have a defective tuner or antenna block assy.
