NOT A GOOD IDEA AT ALL!

You likely now have one of two things happening:

1. Green power light constantly blinks and will not stop(should blink for 70 seconds and go out).

2. Green power light comes on and a few seconds later goes off.

Which do you have?

Tv wont come on


first of all you may unplug about 2 hours and try again as symptom shows some internal overheating or power failure going on

When you turn on power you hear a click and the green light turns on. Three seconds later you hear another click and the green light turns off.


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) and"menu" buttons on front of tv for at least 5 seconds and then release bothtogether.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Let me know what you find and I will assist you.

Samsung model hlt4675sx\xaa projection tv wont work. the stand by/temp light flashes red and the lamp light flashes green? it makes the sound that it makes when it turns on but no picture. we looked at the...


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

I have a mitsubishi ws-65315. When I go to turn the tv on the green power light comes on and you can hear the tv click on, but seconds later shuts off.


this model has a self check, when green light comes on and then goes off. Push and hold both the Menu and Input buttons on the front of the set for at least 5 seconds and release both.

Power light will blink a two digit error code like 2 blinks 2 blinks, a pause and then repeat it several times.

Let me know what error code you find and I will tell you what it means.

TV turns on, then turns itself off about 2 seconds later.


set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

Please help with tv! green blinking light wont stop and tv wont turn on


Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
please post your error code
