Pull out the plug for the TV and leave it out for one hour at least.  Plug it back in and it should be ok.  It will re set itself.

I the same problem and I found that the Capacitors used on the power supply portion of the circuit board were leaking and/or bulging. These parts were failing and as a result the problem worsened with time. If you are able to remove and solder new parts on to the circuit board follow the following procedures. Or get a technician to do the repairs.

1) Make note of connections at back of TV.

2) Unplug power cord and other connectors from back of TV.
3) Remove back of TV with a Phillips (+) star shaped screw driver.
4) Note the position of all connections to the main board.

5) Remove circuit board taking care not to damage any of the components.
6) Locate parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors.

7) Remove and replace parts with capacitors of equal physical size that are (1000 uf ). I would recommend a voltage rating of 25v or 32v. Note that the voltage refers to the amount of voltage the capacitor can handle. The higher the better.

8) Reinstall and reconnect the circuit board.
9) Replace back on TV and setup the unit as before and you’re done.
10) Enjoy!

I replaced the parts for just under $10.00.

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.

SOURCE: mitsubishi projection tv wont turn on, blinking

ONLY 1 of 2 things can cause this problem----

First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---

Notice the one or two pairs of wires coming from the front keyboard of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)

The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---

These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.

If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.

If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---

You can call them and get a quote for repairing the receiver.


Let me know what more information you need--I am here to help.

Samsung lcd tv can't find a source, buttons on remote control don't respond, nor buttons on the control panel on the right side of the TV device


consult the owner manual or call Samsung---this set likely has a lockout feature that locks both the remote and the keyboard out.

You might also want to research this by taking the model number and Google key words "remote lockout" etc.

Goog day. I have a Samsung LE40A559 LCD TV and about a week ago it stopped responding to the remote. Remote itself is working as when the TV is off and I push buttons on the remote the blue light on TV...


The flashing blue light shows that the TV is receiving I.R. from the remote but doesn't mean that the signal being received is recognized by the Samsung. If you have a "universal" remote then your TV code may need to be re-entered/reprogrammed...changing batteries in a "universal" will usually require it to be reprogrammed.

Also...because of the remotes construction (rubber membranes with carbon dots that short across PC traces) I've seen certain buttons stop working altogether.

Timer light blinks on and off and tv wont turn on


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.
If ever resetting is no effect then the problem is in the "DM board"
The constant blinking green light means that the TV is not booting up. This is a common problem on this set. Hope it may help you; Regards, VOTIT

Set top box and remote control


I have the same problem. When I move the 8300HDC away from the TV, or power off the TV, the remote responds. There seems to be some kind of RF interference, which makes no sense since the TV shouldn't emit RF, and the the box should be using IR only for remote input. My TV is a 46" LCD Samsung. Try turning off the TV and see if the 8300HDC responds to powering on and off with the remote.
