Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

If you are getting no video at all, then we can use the diagnostic LEDs and the power LED to help determine the failure.
