We need to know what make and model to accurately answer this question, but if you have a Sony, here is the information -
Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.
The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again. Here is a list of the problems that might have occurred indicated by the number of blinks.
Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
One blink - not used for the self-diagnosis
Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
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.
Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
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.
Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.
Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).
Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

SOURCE: Green light blinking- no picture

I recently had the same problem as well. I called zenith/lg and I bought this model in Jan of 2006. The lady on the phone said they are well aware of the problem. She asked me to have a copy of my receipt faxed over from best buy and then she'll set me up with their repair center. I was barely on the phone with her 10 min. The repair center is coming out next week to fix the tv and all parts/labor are being covered.

SOURCE: No power on LC32D50U Sharp

bobnyc, Is set under warranty? How old is it? Did it display a "perfect" picture yesterday, and not today. How is or was the AUDIO. Can you hear anything or nothing? Is the SMPS power supply board a "COMBO" or is the INVERTER supply located elsewhere? To where do the CCF tubes connect to get power? Tell me, do u have a good DMM, 100mhz Ocilloscope, Isolation transformer, and soldering iron/ solder wick???? If have some answer to some these ??? contact me @ louie12fix on fixya or at lmistyrel @aol.com PS: I highly recomend use of digital cam to take pic's before taking stuff apart. Could help when reassembling.

SOURCE: TV will not power up. red LED blinking 5 times

I always found the problem to be either a combo of the x-sus printed circuit board and the y-sus printed circuit board. It is also very worth checking out your poer supply circuitry as well. Good Luck.

Did you replaced its lamp in last 2-3 years?

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!
