Tv cycles on and off

Tv will boot up and show picture for about 1 to 2 secs then shut off. It just keeps trying over and over. The 5 leds show the boot sequence makes it till LED 2,3,4 at lit. Then it shuts down and recycles again. The service manual does not give indication what the 3 leds mean. Can someone help?

I just went through this as many others have done so I am sure that Hitachi knows it to be a manufacturing and software problem but will not do right by the customers. Judging by the date of your request you may have already found the repair.

The main digital board (part #JP50763) on my 55HDT79 manufactured in Feb 2007 fouled and had to be replaced. It has the new software on it that is supposed to prevent the problem from recurring. Bad news is that the final cost to me was 25% of the original price. Just the board costs $433.00.

How do I fix my power cycling tv??


I have found that the solder connections get loose where they connect to the p.c.b. please make sure its not plugged in and don't touch the hv probe going to the tube. It will be the last time. Be extremely careful and keep one hand behind your back. If that's not it, the power supply has gone south. Get another TV.

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

Panasonic projection TV does not turn on.


Power LED flashes orange 1 x 5 secs. = 1 of 3 fans stopped. TEMP LED flashes 1 x 5 secs, = Temperature error. Lamp LED flashes 1 x 5 secs. = lamp ballast error. (check lamp 1st.)
Hope this helps.

Optoma RD50 TV which shuts down on #1 fan failure


This could be a variant of, or a newer (or older) version of the "DMD fan failure" message.

Symptoms I had are, I stop hearing a fan when the message is displayed.
Then the temp LED keeps flashing RED until I either try to turn the TV on again,
Or turn MAIN power off/on again. BUT it repeats when I try to turn the TV on.
The picture appears normal until this happens ( about 15 sec.)

The solution is to FORCE a normal shutdown by hitting the TV off button
before the message appears.
You should see the power LED flashing RED/GREEN (cool down) and then RED (standby).

Good Day, checho3435;

Look for fluid on the PCB's or check these items:

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source). Good Luck, big IRISH>

No picture no sound


Hi,

Probably, the selftest fails while turning on. If this is the case, press input&menu buttons at the same time for 5 seconds, then the green led will start to blink. Let me know how many times the led blinks.

My Sony tv CRT


If it's between 5-10 secs, that's normal. You will turn the tv on and hear a loud (buzz/hum) that is the picture tube firing up, once it's fired up, it has a few more seconds until your picture comes up fully. That is about 5-10 secs from pushing the power button.

If it's taking longer than that, your picture tube may be going out.

I had a 36XBR250 and it took about 10 secs to fire up and show a picture, and it was 5 1/2 years old.
