RCA 52" HD Big Screen (D52W15)

I have had my RCA projection TV (model # D52W15) for a little over 3 years. I read this TV is the same as model D52W20 without the screen protector. About a month ago the TV made a popping noise and went out. The TV attempts to come on and then shuts off due to what we assume is the circuit protection. With the help of a friend we found a connection loose on what we are assuming is the SSB board. The connection was re-soldered and the TV worked for about a month. A couple of days ago the TV did the same as before. We pulled the board back out and looked at the solder points. We didn’t notice anything wrong with the solder, but did notice two capacitors were popped. We replaced both of them, but the problem did not go away. We reseated the ribbon cables and blew out any dust with compressed air. We also checked the tubes for any cracks or leaks and found nothing. We tried holding down the power button to get the error code(s). One post talks about receiving a 19 error code (one flash and then nine flashes in a row) we could not tell if our error was a 2 or 11 (http://www.fixya.com/support/t104008-rca_hd_model_d52w15). We unplugged the control panel as stated in a previous post and it did not change anything (http://www.techlore.com/forum/thread/18490/RCA-52-quot--projection-tv-mo...). Does anyone know where to find an explanation of the troubleshooting codes? Any suggestions on where to go from here would be greatly appreciated? I apologize for the length of this post, but I wanted to supply as many details as possible.
