SOURCE: tv wont turn on get audio then tv shuts off timer lite blinking

If TV stays in stand by with audio but no video, then common faults are the ballast board, or a fault on digital board.

If the led stays blinking , and tv turns off then the TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

The ribbon connector which goes from the FMT to the DM is disconnected or not seated properly thats the only thing that will cause the 4 4 error other than a broken ribbon socket

SOURCE: blinking timer light and cannot turn on

How many times does the LED blink? Does it blink 6 times, pauses, and repeats? Or is it some other number of blinks? Or does it just blink continuously, once a second? (Note: on Mitsubishi's it is normal for the TV to blink rapidly for about 90 seconds after you plug the TV in, while the TV runs internal self-tests.) If the LED continues to blink continuously after 90 seconds, then the problem is on the DM board. There are 4 electrolytic capacitors, grouped together. I believe they are either 820 uF (mfd - microfarads) or 1000 uF at 16 Volts. If you check them, you will see that their tops are swollen (slightly rounded; not flat across). They will check okay with a capacitance meter or ESR meter, but don't believe your meter! Replace those 4 capacitors with either 820 or 1000 uF capacitors rated at either 16 or 25 volts. Make sure you use good, high-temperature (105 deg C) low-ESR capacitors. I recommend the "FM Series" capacitors from Digi-Key corporation, part number P12366-ND or P12379-ND. Less than $1.00 apiece. Good luck!

Timer light blinking and tv won't turn on


Not much info to go off of, and the video is a bit blurry. Try unplugging the tv for a minute or two, make sure to leave it unplugged to allow power to dissipate. Then try again. Otherwise I would suspect power supply problem.

I recently replaced the TY-LA1000 lamp but I'm getting a yellow flashing light that goes on every 5 secs.I made sure that it was installed correctly and tried resetting the timer by pressing + and - o


Yellow flashing light? Did you get any picture? Bet, not!
It means: your lamp door interlock is not engaged: did you forget to turn the locking knob? Did you install lamp compartment door? That might be the only issue. Lamp timer blinks 'red", while TV works normally. Reset the timer, it's gone, along with annoying message. Yellow means: interlock or thermal protection is off. Try to repeat lamp installation procedure. then, you'll find out your mistake. don't need to remove the lamp. It would be "red", if lamp won't fire up.
good luck,
Alex.

No Picture - Sound


I just had this problem fixed. In my case, it was because the insulation on the CRTs was cracked, and when it would warm up, the shielding would separate and would let 5000 volts arc across the main board. This, obviously, damaged the board. The tech didn't catch the arcing right away, so they replaced the main board twice before they used a high-temp RTV to patch the insulation.

The power-cycling was a result of the damaged board.

The point of this story is that the broken part may be a symptom of the real problem.

I hope this helps someone!
