About the second user with the remote problem, the problem is likely a bad IR sensor/board inside the TV, The IR circuit is the one that receives the remote signal.

About the original problem with the light blinking instead:

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.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

Hello
There is a system reset button on the front panel of your TV. You have to reset it. Resetting will bring all the settings to factory defaults. There is a small hole on the front panel. The reset button is behind this hole. To reset do the folloing:-

If the TV doesn't respond to either the remote control or the front panel controls or will not power off, press the SYSTEM RESET button on the front panel with a pointed item such as the point of a ball point pen or end tip of a paperclip.
The TV will turn off and the green led will flash quickly for about one minute. When the green led stops flashing, you may turn on the TV again. The changes you made while the TV was most recently on, before you used the SYSTEM RESET button may lost, however, the changes you made previously are not lost. Only those changes since
power On may be lost when the system reset button is pressed. All other settings are retained.
Ok.

How can I reset a Sony Wega tv without a remote control... I stand by button keeps on flashing and the tv wont stay on for more than 3 sec.


You can only reset the TV when you have the remote as it requires holding down the RESET button on the remote control, then pressing the POWER button on the TV front panel. The TV will turn itself off, then back on again. Then release the RESET button.
Regarding your problem with the TV not staying on for 3 seconds, you can try unplugging the unit for at least an hour to perform a hard reset of the microprocessor. If the unit still doesn't stay on, you need to check the power supply or the entire board for any blown or bad capacitor, shorted terminals due to accumulation of dirt, or broken solders. It may be a tedious task and requires an electronic prowess to do.

Mitsubishi ws-65615 tv flashing timer light. tv


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 keyboard2.gif 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 keyboard2.gif 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(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 keyboard2.gif 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.

Flashing green light


Did you try this yet

SYSTEM RESET
If the TV will not respond to either the remote control
or the front panel controls and/or will not power Off,
press the SYSTEM RESET button with a pointed item
like the end point of a paperclip. The TV will turn Off
and the TIMER light will flash quickly for about one
minute. When the TIMER light stops flashing, you may
turn on the TV again. Changes you made the last time
the TV was On before you used the SYSTEM RESET
button may be lost, however, the changes you made
previously are not lost.
POWER/TIMER Indicator
The green light is a multi-function indicator. This light
will flash rapidly for about one minute each time the TV
is plugged into the wall electrical outlet, when power
is restored after a power failure, or using the SYSTEM
RESET button. Do not attempt to turn on the TV again
during this period. Wait for the flashing to stop and
the light to turn off, before attempting to turn the TV
on. While the TV is powered on, the light illuminates
steadily. If the TV has been programmed to turn on
automatically using the Timer feature,

Power light blinking


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.

Color wrong...flashing red light


The light that you see flashing is the timer light. It is flashing because of the lack of red, green or blue. This would explain your color issue. It could e caused by the CRT (picture tube) itself or a bad connection to the CRT or a color driver component failing. Either way you need a technician to locate the issue. If its the CRT and it is out of warranty, most likely it won't be worth the repair.
