Re: Samsung Rear Projection 47" TV goes into stand by on...
I am sorry to disappoint you but a TV problem can only be fixed by electronic technician. If you want to do it yourself, you would have to learn electronics. Start by learning basic electronic, and then read a book on how to fix televisions. Without knowledge in electronics, you won't be able to understand a book on fixing a TV. I have been fixing TV since 1998, and I started after dropping out of electronic engineering class. I learned most about electronics on my own, and you can too.

The tv have a problems known as a convergence problems,it dead.The tv colors lines R,G,B mis alignment,have colors shadows or look like 3D pictures.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts on the tv convergence board is dead,must be replaced to solved the tv picture convergence problems.The shop,will cost u $300-350 for parts and labors.
The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

This is a convergence problem and if you can solder, you should be able to fix this yourself. First open up the back and locate the convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. Post the markings here and I'll confirm you have the correct ones. Try resoldering the pins on the ICs. If that fails to resolve the problem, you will need to replace them.
