I have a 37 inch lcd hd tv made by Curtis model 3717A. I bought the set about 18 months ago. When I attempt to turn the set on either manually or by remote, the on/off light begins flashing but there is no picture. After leaving the set unplugged for several hours I was able to turn the set back on. Since that time I stopped using the tv's on/off, instead just using the cable box. My cat stepped on the power strip yeserday and now the tv will not power back up. Help.

My Sanyo DP26648 is completely dead. If I turn it on, the power LED comes on for about 5 seconds then goes out. I can repeat this twice, and then the power LED won't even come on. Unplugging and then replugging the TV will once again allow the Power LED to come on for 3 cycles in attempting to turn on the TV. I guess replugging in the TV allows a capacitor to recharge and power the LED? Is this TV repairable or is it time to replace it?
