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.

I have an LG 60PV400 plasma TV. While watching TV the screen goes black but the sound keeps playing. Sometimes the sound will just keep playing. Sometimes the TV while shut off.


Hi Joseph

Not sure what the LED codes will be. LG Tech support would know.
Is it under warranty still? If so, then get it to a service centre.

If not, Then you might want to check for leaky Electrolitic Capacitors.
This is the biggest ploblem with modern Digital (computer) Flat Panel TV's
Might be a little early to spot the "Bulging" or leaking until it gets worse.
If your up to it & you can spot the bad caps & unsolder & replace for a few bucks.

Good Luck

TV goes to blank screen standby after one second of normal functioning green power light on. When in standby state, the TV is blank like it's off and the red standby light blinks FOUR times.


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. http://electronicshelponline.blogspot.com/

THREE Blinks
B+ over voltage protection (OVP), unit goes to the standby
mode then displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
FIVE Blinks
AKB circuit (AKB), the timer/standby indicator blinks for about
30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,
try turning up screen slightly.
