No picture or audio.power light blink on once and turns off

My pioneer 5020FD Kuro tv. when I plug power to the unit, a blue light blinks 8 times pause 2 sec. and blink 8 times repeating this and if i press power button it clicks red light and makes a clicking sound and goes back to the blue light blinking again, it did this once before and the picture came on fine until i turned it off and now it just blink the blue code.

um u should turn your tv off for like 10 minutes , i think yourr tv is a internet tv so let it cool sometimes sony internet tvs freeze with black screen so try it out.
good luck :)

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

Hello,

Once your television blinks about 9 times then it means there is a problem somewhere most likely the lamp of the television. Another source of this problem is also a bad capacitor from either the main panel or the power panel.

If your remote turns off actually it is because there is nothing to operate on the television, so once your television starts the blinking light, the remote will not be able to operate the television, once you unplug the television and plug it back then press the power button, the remote will do the same.

Until the television is fixed is when the remote will work normally.

Take care and good luck

The codes are....0650,0226,0108,1650,0037,0367,0516,0361,0056,0548,0853,0163..PROGRAM..Turn the TV on, press the TV button on the remote, press and hold the MAGIC button until the LED blinks, the light will blink once then twice, enter one of the four digit codes, the light will blink twice, press the power button,the TV should turn off, if not, repeat the steps using a different code until it does....hope this was helpful....

.there are several codes. try each one seperate.

1. press and hold setup button until the red light stays on.
2. press and release the desired mode button (example t. v.) the light will blink and then stay on.
3. enter one of the 4digit codes.
note: if the code is valid the light will turn off if it flashes it is an invalid code.
4. with the device on press the channel up and down. if the remote only controls some of the functions try another code.


CODES:1171,0116,0167,0176,0922


1.manually turn on the t.v.
2.press and hold the setup button.
3. press and release the tv button the light will blink once and then stay on.
4.press the channel button repeatedly up to 300 times until the device changes channels. the light will blink and then stay lit.
5. press and release the mute button to store the code the light will go off.

If its a four digit code remote. I may be able to help.. Try these...0171, 1204, 1326, 1517, 1963, 2002..
Good luck
