Question about Mitsubishi VS-50707 50" Rear Projection Television

1 Answer

No signal through Ant-A and/or AntB

I can not get a signal when the coax is plugged into Ant-A and/or Ant-B, its just static. I can veiw cable when I run it through the vcr and change the input to input-1. The same time the Antennas quick working, the remote to the tv did as well. The remote still works on all other components.

Projection TV. DVD works. Cable often seems, "untuned". Static & un-fine-tuned sound of channel with black screen. Then, later, it will come on just fine. Sometimes, will go back to untuned status.

I would suspect your cable box first. I would unplug the power cable from your cable box and wait 60 seconds. Plug it back in and try to watch cable tv. I would also make sure the coaxial cable going from the wall to your cable box is connected properly. I would also make sure the cable going from the cable box to the tv is connected properly. Test your tv and see if it works correctly when you watch cable. If this fixes the issue you are good to go.
  • If this makes no difference use a set of new cables if you have them.
  • If this does not work then call your cable company. They may have to replace your cable box.

Static on Powering on

You can start out by resoldering all poor solder connections and look for bad capacitors they will be puffed up on Top.

When I hook up my cable box to ant a or ant b I get static, but when hooked up to inputs 1-3 I receive a good signal.

Call a good TV Tech and tell him your TV's Tuner is not working. He can then give you an accurate estimate to repair by phone.There is likely an open resistor / fuse that is not letting power get to the Tuners. That is a 31 volt DC power line to the Tuners.

these are not cross compatible an rca hook up is a base band signal basically raw data, and coax(cable line) is a frequency with a carrier best suggestion I have is to buy a vcr with a coax out put and rca input that way the vcr can pick up the video signal then remodulate it onto a channel frequency and send it to the tv

You are losing a VERY small amount of signal using the transformer. It won't even be noticeable I'm sure if you switch to the coax in but the fewer connections you go through the less the chance of a bad connection. Use regular " Ant. In " coax connection or " RF in" whichever the wording is on the back of your set. Good Luck!

Hello,65613 mits

Good Day, boofis68;
Sound like you may have voltage concern,9 volt source. Check for 9-volts DC to the Terminal PCB at connector JA pins 57 and 58 if missing, check IC9C25 (9-volt regulator) part # 270P677030 on the Signal PCB and replace the two caps. Good Luck, big IRISH.

Mitsubishi rear projection no picture and static sound

I assume you are using a cable input, such as a box or the main Cable line connected directly to the TV. examine the main Cable Coax, look at the copper wire that sticks out from the connecter, make sure it is long enough, if its to short, gently pull it with a long nose plier until it reaches the rim of the connector. Sometimes when connecting the coax to a source, the copper wire in the coax is to short to make contact, and as a result you get no signal. Hope this solved your problem.
