Picture shadow on rear projection Sony big screen TV


You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

Samsung 1080i compatible tv 42 inch


This is very common with Samsung and is considered a overheating or lamp issue. cheapest fix before changing out the lamp is to unplug the unit after it has shut off its fans and open the back up and blow all the vents and circuit boards off with can of compressed air. Then remove the lamp to get to the larger fan that is behind the lamp, be carefull to not let the fans to spin when you hit it with the air because it will spin the fans faster than they are ment to spin, so gently place a finger on the blades just enough to keep the fan still and clean off any dust you see on the blades and area. Put everything together and give it a test run. If it stays on longer you know it was just to dusty to stay cool , if no change then try the lamp.

2003 Samsung HDTV 1080i 42" wide screen has just developed picture problems distorted and red. Almost looks 3D. MODEL NO.:HCN4226WX/XAC SERIAL NO.: 37083CEX400297E


This is a convergence problem and can easily be fixed either by resoldering the pins on the convergence ICs or by replaceing them if they prove to be defective. Can you solder? Do you feel confident in replacing these parts?
Keep us posted.
