    Need model # of set, but basicly it sounds like a driver ic for the panel blew up. You should be able to open the back and see a hole blown in one of the ic's. Probably near the side you saw smoke coming from. It needs to be replaced. On some models, they are epoxyed over and cannot be replaced. which means you need a new set. Or at least a new panel. But it is usually cheaper to purchase a new set with better warranty and newer features. Good luck. and let me know if i can help you further. Guru Jay... Have a great day.

Yes it certainly sounds like the panel driver IC blew out and depending on the manufacturer, you will need to have the entire panel replaced. It seems manufacturers would have learned their lesson by now with the panels and made separate drivers for them.

Hello, A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed. This will cure the problem as they overheat being sat next to a heatsink that gets very hot! Try and change them for the same 3300uf but a higher voltage.
I hope that this help to rectify the fault of the projection TV....

Red band at top of tv


Hi,if its a an LCD RPTV it sounds like a light engine problem.Basically your tv uses 3 LCD chips that create the image .Each chip is like a tiny screen that blend together to get the colors and picture right.They are green,red and blue.When they start to fail you will start to get color discoloration or that red band you are getting.May the Lord Jesus bless you!
