We usually refer to this event as the "kiss of death" syndrome. It occurs because the protection circuit (a sort of electronic fuse) has sensed that one of the many sections inside your tv has exceeded the normal current flow. This is generally because of a shorted condition somewhere in the circuitry.

The protection circuit shuts the set off and keeps it off until the fault is corrected. You can sometimes get it restarted by doing a reset. Do the reset by unplugging the power cord for 4 hours; then power it back up.

The problem is, if you cannot get it restarted, that you don't know where the shorted conditions are. It could be in any of the nearly 10 sections within the tv. It requires an expert tech who knows how to get inside, defeat the protection circuit and test the various sections.

Most common is a problem in the high voltage/horizontal section or the vertical deflection amplifier section. These repairs are quite expensive and will run as much as $200 to $300 - sometimes more.

So, I cannot give you an exact repair estimate because it is impossible for me to predict where the problem may lie, but most of the time it is on the expensive side of the range.

Sorry for the bad news.

I have a Hisense led tv model F39V77C.


Yeah, replace the set since it appears to be trashed. But if you have a few bucks lying around you might want to try replacing the unit's power supply to see if that resolves the many issues you have.

Panasonic TC-P55UT50 plasma went black. power light blinks 7 times, pauses blinks 7 times. Is this a power board? or Y-Sustain?


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.

My Sony KV-36XBR800 will no longer turn on when power is pressed it clicks and sounds like it's turning on but the screen stays black and the stand by light blinks 7 times.


7 times mean no horizontal deflection. So check horizontal output an solder of it and associate parts.Often resistor and transfo driver of base of h. output.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!
