SOURCE: TV on/off light keeps blinking red light/no sound or picture on screen

Here's a solution that I received from an TV expert in another website: "This sounds like a power supply problem. i have seen it several time on your model. i would not keep trying to turn it on it might damage something else in the tv. the reason it is shutting off is because the power supply is putting out too much voltage. a repair cost will range around 300-400. this is a great model and well worth a repair. here is a web site that might help you in finding a repairman.
http://www.nesda.com/locator/state_search.php." <-- $300-$400 is too much! But throwing away a 300lbs TV will cost a lot of $$$ for the towing and dumping too. I haven't decide what to do yet.

How many times is the LED blinking in between pauses? that is possibly a error code if you can determine the number of blinks.

SOURCE: standby light keeps blinking. tv wont turn on

If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

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

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

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 , starting the flashing light.

If you are in situation one, then the TV 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.

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.

Green light blinking, tv won't turn on


Lamp lifetime is not 100% predictable. A lamp may fail without notice, although this is not usually the case. The picture is more likely to become noticeably dimmer as the lamp nears the end of its lifetime.

While there is nothing wrong with using a lamp until it fails, some customers may want to purchase a new lamp and replace the existing one when they notice that it is aging.

If the lamp fails in a Mitsubishi MicroDisplay TV, there will be no picture on the screen and a red front panel LED indicator will illuminate.

Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

The power light is just blinking red on my panasonic 1080i hdtv. cant even switch it off using the power button. picture and sound come on for about a second when the tv is switched on after power cord...


The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

Power light keeps blinking Red and TV will not turn on


Is the light blinking constantly or is there a long pause then more blinking. If constant check the lamp door switch . Usually it is broken or jammed. If you jumper it and the set comes on that it. 4 blinks is bad fan.
