Question about Dynex 19 in. LCD Flat-Panel HDTV
I would suspect that your powersupply isn't giving the correct voltage to the mainboard (aka, tuner board) Once you open the tv, look for popped capacitors that are needing replaced. If you find any you will need to replace with the same uF value but a higher V value. This will correct the issue for the mainboard's voltage needs and you will notice that it will solve your problem.
If the power supply has been blown for awhile a mainboard replacement may also be needed, but I would try to fix the powersupply first to see if that corrects your problem!
