I think the tuner on the set is out , no picture or sound ,but I can play DVDs or other video source .. I checked the cable and it works with other tvs.. If the tuner is out can I use my Denon receiver as the tuner to the VS 45605 rather than replacing the tuner? Thanks R.D.

Need to know if set had any symptoms before it lost pic. These sets use a protect cir. IF it lost Vert sweep it will shut down the pic. IT was a common issue Mitsubishi used a kit to repair . IT is called the ic401 kit.
You are on the right track. If you cannot see a picture on either antanna A or B then the tuner is suspect.
You may try hooking the cable straight into the TV if you are using a cable box, if not then you should be getting a picture when your other video devices are turned off.
The fact that you get a picture on video tells me that the AV circuits are fine.
you probabily need to change the input, find the input button, when you hit it you should get a box on the screen, with inputs, highlight diferent ones and hit select- untill you get pick back, thats what my sugestion would be
The first things to check are the filter caps in the main power supply area. Usually this rolling is caused by 60 cycle hum coming from the wall. Try that first and update this with your results. Also, while you are in there, resolder any joints that appear grainy or have rings.
To all accounts it does, this can be checked by verifying that it has TWO antenna inputs. To get the PIP working, you will need to split and feed both antenna inputs. Seems to be set up this way to cater to PIP with set top boxes/convertors that have RF outputs
the 2 tuners can be spotted as the shielded assemblies with covers either side in the lower right corner of this pic. There is a mod floating around that involves bypassing the PIP to fix a fault that the set develops. This may have been done to your already.
If it works the way you have it setup now, leave that way. Plug all your video sources to the denon if possible and leave it that way.
If the denon has the feature to change channels like a cable converter then you can use it or if you still have a VCR you can also use it as a tuner just to tune the cable channels and use the audio/video outputs from it to the TV or denon receiver.
The tuner might not even be available anymore and if it's, is expensive.
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems, to activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source
You can buy a PIP circuit card on the internet(about $15.00) that can replace your current PIP card. It will bypass the PIP function which is most likely the problem. Instructions for instal come with new card. It's a relatvely easy task if you are in anyway technically capable. Worth the try. Rexman
