No sound,picture ok

When was the last time u replaced the projection bulb,yes it could be that simple the projection bulb it dead.The bulb last only about 1 or 2 years,by using the tv on about 4 or 5 hours a day.

If the convergence option is still in the on screen menu its usually related to resistors on the convergence power supply board

a professional. Electronics go threw a self diagnostic to check for problems. it sounds like it's found one.

normaly the audio ics go bad cap or 2 make sure audio sing is present on input of aud ic if so chk opt if opt bad replace ic and capacitors around ic good luck this should fix ur prob parts nte semiconductor.com 25.00$

Go into the menu and set contrast to full, bring brightness up to an appropriate level after.

Don't understand why, perhaps rca contracted microsoft for their programming, but when I unplugged the TV and it rebooted, everything is fine. I still am concerned about the warning on the back.

Ok. no U can hear the audio for the channels?... this set has no bulbs to replace. does it shut down. does the front green light flash. if u push menu on remote does anthing come up?

Sounds like it could be the entire light engine.  The part is available on the Internet, but it runs $700 - $1200 without the lamp (although it sounds like you could use your existing lamp without a problem). These parts, however, are notoriously hard to find and may be backordered for months.

May not be worth the cost, but that's up to you.

1)replace convergence IC's w/best quality. re-align as needed. 2)recheck audio,source and selections in menu. PVAT!

i founfd this, it could be the problem. Symptom: NO VIDEO Cause: Found L306 was open. B+ to pins 21,22 of PFC2 at the FC. find L306, will be hard to find with all the boards, but L306 is a coil. if you can find it use a multimeter to see if it's open. 450 sound slightly high but if you have a service call or pickup & delivery it might be right. hopefully you find the coil bad. good luck.
