Question about Mitsubishi WS-65869 65" Rear Projection Television

1 Answer

Mitsubishi WS-65819 2002 rear projection

When you turn the tv on there is no picture on the antenna a or b channels sometimes there is audio other times its all just snow noise but no picture. this last for somewhere between 1 min to 5 min and then the picture comes on. sometimes it will go on and off during this time. If you use an input such as a dvd or any other not utilizing the antenna a or b input the picture comes right on no delay at all. WE usually watch a dvd while waiting for the antenna inputs to work. tried a/v reset and turning power off. Perhaps its a input problem. i did take the screen off and dusted and removed cobwebs from circuit boards but no luck. what do i look for for ?

1)possible bad RF modulator (the small box the A or B signal first goes thru) 2)Bad tuner (mounted on signal board) 3)or missing voltage to run tuner You could replace signal PCB,but that gets a little pricey.

Mitsubishi Rear Projection TV Model WS-55311

Rear projection TVs are dinosaurs. Sell it if you can get anybody to buy it and get an HDtv they're pretty cheap now not to mention thinner, lighter and better for your eyes. Imagine the space you'll save if you mount it on the wall and the cost of electricity. Not trying to be a jerk but it's time to move into the 21st century. The picture is waaaaay better.

There is not reception. Antenna A failed a year a go, I switched to Antenna B and now is not working either. When I connect Cable (COX) antenna inputs, A & B, do not detect it. My TV is a Mitsubishi...

Check if the video /audio input( AV) works ok.If so the tuner inthe set is defective and must be replaced.
please replace one to confirm after checking the +B voltage on the tuner being present.

Can't seem to add HD channels to Mitsubishi WS-65513

You need to run an external antenna feed to the air DTV input jack, bottom left. You can use your loop out if you already have an antenna connected to your antenna A input jack. Create a DTV device, then run your antenna setup for DTV.

No Audio with HDTV on Mitsubishi WS 55859; no problem w analog tv

Have had bad exprience with RCA converter boxes. The box will lose audio and has to be turned off and then back on. You may want to hit mute during this process, the volume varies from analog to DTV. If you have no problem with analog audio I would look into a different converter box.
