Was watching tv something popped tv shut off.now power comes on but no picture or sound

The main power supply board has to be troubleshooted. It is best to replace it as card basis.

The television is shutting itself off to protect itself. The blinking light is a code pattern. The specific code determines whether or not you need an LCD Controller Unit, Main Board, power supply or something else. You would need the service manual. There are parts distributors you can get it from and the parts as well. If soldering and tv repair is not something you are entirely familiar you may want to seek a tv repair person. The manufacturer's support may walk you through the service menus to complete a factory reset depending upon the symptoms.

You will need the y and x sustain boards replaced, possibly the buffers. very expensive repair. you can replace one board but its best to do all of them.

Power board short and bad capacitor blown, capacitors usually pop because of shorted or open rectifiers and linear devices that warp inside. This happens due to excessive heat exposure from the current draw. Bad diodes and FET's are usually the root cause as to why capacitors bulge then eventually pop. This means the the x-y sustain boards are not getting their supply voltage resulting a no picture....

The red light flashes an error code for a technician to read, the tv is in protection mode to prevent further damage. Get it serviced at your local repair center or take it back if its under warranty.....

I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Best Regards and Smper Fi

if you could see light orange or green is has power is probably teh Y and Z board

It is a power supply problem. As your set is nine years old all the electrolytic capacitors at the power supply area may be out of range. If you are not familiar with electronic repairs it is bettter to take to service center to check and decide according the cost you will asked.

Hi! I think something to do with power supply.Try using different power outlet or have to replace the fuse inside the unit.If your tv is withing the warrenty dont open it,call samsung

Burnt small 2KV capacitor near flyback xformer....original is
221K....I use 271K / 2KV ...Possible burnt 1K 1/2 watt resistor
and shorted zener diode ....ECG 519..................T.
