Television and Home Theater

I am going crazy here, because I fixed the issues with the green blinking light with no picture, Thanks for your help everyone, but Now the tv just shuts off giving me a message that the tv will shut off to check for air flow blocked.

 I can't find a fix or a part for the thermal sensor, nor can I find the temp fix to determine if that is the main cause. Anyone dealt with this or have a test to narrow in on the route cause.

Please help.

Hello:

 I have a WT-46809 that stopped working recently.  If I turn it on, I get a quick flash of green text on the screen and then it shuts down.  Checked the diagnostic code, and it's a 21 (X-Ray Protect circuit).  Based on seaches on this forum, the problem could be a large number of things.  I checked all the fuses and they are all good, including the pico fuses.  I don't see any obviously leaking or mushroomed caps.  My question is two-fold:

Is there anyway to test a STK392-570? I just ordered some off of what seamed to be a reputable

dealer on Ebay. But still have convergence problem . I checked all the pico fuses, they tested fine.

I would of bought them from MCM or Electronic-Repair-Kits, But they are sold out! I have done this before on another tv with no problems!

Please  Help!
