Chassis is ATC010a. When i plug it in, it makes a clicking sound. When i press power...it turns on for half of a second and then goes off. The green power button flashes over and over and then stays on after a while. No picture, No sound. I need assistance with this. I found this TV...I know alot about computers, but TV's lol no way. Can u help me?
I'm experiencing the exact same problem. same model and chassis number. I've tried searching the web for the schematic (this is how I found your response, BTW), to no avail. Any clue as to where I might obtain a schematic?

I Just started to service one of these RCA ATC-010 chassis,I found a shorted Horizontal Output transistor 2SD-3402.
This could be just a failure of the transistor itself or the transistor failed because the flyback transformer has either shorted windings or internal diodes. These parts are not expensive,I suggest replacing both at the same time to save yourself future aggravation.
I have to jump start mine from a fault switch with an extension cord, once it starts up, I unplug it real fast and plug it into the normal power bar, and just don't turn it off

It is the 169 chassis-over 300 different models used it and are different-answer something for me--does it have a GREEN power light that comes on for a second and goes off?
I know this set well and to be honest hated working on them--Let me know about the power light and I will tell you what I know.
At one point in time this was a very good set--I do understand about paying a lot to get it fixed and having it bad again.
I am here to help people and I bet I know more about this set than almost anyone else here.
It sounds like the High voltage transformer has gone out. If you open the back of the tv and look on the right side, you will see a large (4 - 5 inch) black cylinder with a large wire coming out of the top. without touching anything, look and see if it is cracked.
IF you would like help diagnosing your set. Go to the enclosed link. They have the service manual for your set and offer unlimited chat support for only 29.99. Just click on your sets manufacturer and you will see your model. Then click on the contact us link and provide your email address and they will email your manual and instructions on how to obtain your support. I am one of their techs. This manual contains step by step procedure for troubleshooting Your RCA DLP Light Engine http://servicemanuals.vstore.ca/
This sounds like something best handled by an experienced tech since the fix involves extreemly high voltages nearby, If you have a very good knowledge of the inner workings of tv's then ask for more information.
If you blew the fuse, the TV would do absolutely nothing - no lights, no sounds, nothing. It could be that the loud zapping noise you heard was the high voltage transformer arcing or shorting out. This could have caused the horizontal output transistor to short, and the set will not start as a result. You should have the set serviced by a qualified tech.
I have the same problem-still troubleshooting...so far still not find the cause. DM1 power supply output voltages are operates correctly. Signal output of microprocessor up and down (no good) that turn on Q14105 and latch optical isolator U14102 to power the unit but both of ohmed out ok. it hard to troubleshoot the main board with power on.
