Same problem: LA40R71B

My Westinghouse LCD tv has the same lights on it It goes orange or red when there is no signal from that source... or while it is calibrating itself to the new frequency etc.

The problem may be in any three things.No 1: Internal power supply.No 2: The video section.No 3: IFT (Intermediate Frequency Transformer).
Solve:Check all the section one by one and find out where the fault lies.Then repaier the faulty components.

You need to check for standby 5vdc, it should be there the minute you plug the TV into the outlet. This a must have voltage. Replacement power supply is only $53 here: http://www.shopjimmy.com/catalogsearch/result/?q=Samsung+LN32A330+
Please post back what kind of voltage reading you are getting at the DC output connectors.

Sounds like maybe you have a sleep timer activated?  There should be an option to reset the tv back to factory reset, this might help you. 

Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan

what model of Sony is it? On many of the Sony projectors, a 3 flash error code indicates the lamp is not properly seated/installed or the lamp door is not closed properly

Unplug TV, take off the back. One each board there will be capacitors. the tops are flat unless one has blown then it is bubbled up. If you find one that is bad, copy the number and search the internet for a replacement. Unsolder and remove the old one ( there is a line drawn on the negative leg, mark the neg side on the motherboard so you can replace the new one the same way). Now solder the new one back onto the board. This worked for my TV, hope it helps

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

This is Sony's way of telling you that there is a short in you set.Probably the horizontal deflection circuit.(Horizontal output transistor shorted??). Also any other short. You need to take it to a techincian and have it checked out. It would be wise to get an estimate! Stargazer
