Question about Mitsubishi WS-65819 TV
TV Powers up and you can get to all the menu screens but no video, only audio. Tried for picture on Ant A and Input 1 and 2, all hooked up to different components but same results. If you disconnect the RCA Video cable the TV goes into the 2 minute shutdown mode and when reconnected it goes back to a blank screen so I know it senses the video signal. At first thought it was a setting (one year old remote lover roams the house) however I have been through everything I could find and can't get the video back, there were no problems leading up to this. After cleaning all the dust out there are no apparent problems with any of the boards but 90 percent of the time they aren't apparent.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

This sounds like a bad connection or a bad capacitor in the 220 volt source that supplies the voltage for the CRT boards. You will need to get a schematic and trace out this voltage from the PM board to the CRT driver boards when the set acts up. it could even be a connection on one of the plugs from the PM board to the CRT boards. Sorry but not a real easy repair. Might take some time to trace unless a component is failing. Good Luck

check if your unit is cable compatible.if not , you need to buy a cable converter.much better if your cable converter has audio/video out.

need to replace the stk's and some other caps, usually have to resolder the chasis on both convergence and power supply chassis.
