Television and Home Theater

  Hello,i asked my partner to change channel as i disliked the chap that was on,and blow me down,the tv went into standby.She now blames me for no tv!I am an amusement arcade tech and work on all sorts of electronic and electro mechanical equipement,and in the past vectorbeam and various monitors(few yrs back).Anyway,standby,flashed once,stayed on.Got service manual,entered service mode via remote,led off and 16khz?

Have a Mitsubishi WS-55807 with the following symptoms:

1- TV stays on. Sound is fine but there is no video on any input. I can not check for progressive scan. I can see the OSD. I have convergence problem.

3- Heat sink of convergence ICs is cold (even after replacing the ICs). I measure correct voltages on the IC pins (-24 volts and 25 volts). I don't get any convergence grid (crosshatch) following the instructions.

4- Measure 12 volts in and 9 volts out on the IC9C01 and 05. Correct voltages also at IC9C02.

I have Sony Viao Laptop and Sony Bravia LCD TV, ia there a way to connect to the TV Wireless instaed of AVG?

If not, can I connect with AVG and use Vista Media center TV using the LCD TV tuner in the TV?
