Seven blinks indicates a high voltage shutdown which has exceeded 33,000 volts and immediately sends the unit into a safety shutdown. In this case you would need to check the power supply regulation circuit and horizontal circuit for the failure. It could be as simple as the horizontal output transistor having failed to something more complex or expensive. Need to have it diagnosed for that to find out.

Mom's Sharp Aquos TV no sound or picture there is a green flashing light where the power light is I heled the volume up and channel down while the TV was unplugged. plugged it back in sound no picture


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Here's my suggestion , unhook all the external components to the TV and leave the TV unplugged for more than a few minutes (a day/overnight). The next day plug the TV into the wall outlet (not the powerstrip) without anything hooked up to it, and turn it on. See if it comes on. Sometimes unplugging for a few minutes/hours is not long enough for it to reset itself.

Panasonic cinemavision 1080i power light blinks red twice, will not turn on


The clicking sound is a safety device that prevents that TV from starting because a fault has been detected.

The fault is also indicated by the two blinks. Two blinks point at a problem with one of the low voltage lines (it should be 15V) from the power supply. The PSU is the part to be tested and eventually replaced. Before calling the technician try to unplug the power cord and leave the TV to rest for about one hour before restarting.

Wont turn on


sounds like the tube is out. could be the transformer but probably not. I don't recommend you try fixing this yourself.

However some rcas are funny: unplug it again and leave it unplugged for about an hour then try again.

Power button is green - no blinks / no picture / no sound


Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.
