The timer light keeps blinking fast. tryed shutting the tv off and plugging back in and it works for five min. then goes back to blinking

I have a 70 inch aqua sharp tv. The model number is LC-70LE857U. The stand by light blinks 2 times slow, 5 times fast. Tried resetting the TV.. Nothing changed. Please help.

One of two things...first hold power button while you hold the up button on your remote, this will reset your tv to manufacturer's settings....you could have sleep timer on.....if this does not work, you have to replace the lamp, my tv did the same thing and it happened to be the lamp. Hope this helps, good luck

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!

check your sleep mode...

It seems this is a self diagnostic function. the official sony codes are as follows

• Five blinks - AKB circuit (automatic kine bias), 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. In addition, unit could be in IK blanking, try turning up screen slightly.
  
• Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.

It sounds like you have a video input problem. Have you unhooked all inputs from the TV and tried to power it back on by itself? Hope this helps

it must be recording soething have u got IQ?

Check C81A2, C81A3, C81B3 and C81B4 (1000 uFD, 16V, 105C) on the DM PCB.
Check C8F19, C8F21, C8F22 and C8F27 (1000 uFD, 16V, 105C) on the FMT PCB.
If any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).

POWER SUPPLY PROBLEM.YOU MUST HAVE SOMEONE REPLACE TWO TRANSISTORS,VARISTOR,FUSIBLE RESISTOR,4 CAPACITORS & HORIZONTAL OUTPUT TRANSISTOR & RESOLDER PINS ON HORIZONTAL DRIVER TRANSFORMER.GOOD LUCK.4TUNE

it sounds like the 1000 mfd 16vdc caps on the dm board have gone bad, but with out a model number it is hard to be sure..

hold the menu bottun for 10 seconds
after press power

see if that works
