Not working i turn it on and my blue light comes on but flashes about 5 times then yellow light comes on and it goes completely off. help please

Hi,
This tv has 3 indicator lights on front, Power, Lamp and Temp
I assume Temp light is blinking 5 times after every 5 seconds, if that is correct then it is problem of clogged air filter located in light engine that need to be cleaned.
Below is an image of light engine and air filters locations are marked with red circle, it is job of professional to fix this issue because complete light engine need to be take out from tv cabinet.
Hope these info will help you, let me know if you have additional question or need service manual copy if you want to repair tv by yourself.
Thanks.

You replaced the lamp. Did you have a look at the PSB-Power supply board for blown capacitors? They should be completely flat at the top (X).

Check the batteries. Use good quality bateries for these digital cameras. I would highly recommend good quality rechargeables.

I had the same problem. The many instructions available don't have quite the right details. This worked for me:

1. Turn off the BT150 by holding down the answer button about 5 sec. until the blue light goes off and is not flashing.
2. Turn on the BT150 by holding down the answer button about 5 sec. until the blue light flashes.
3. Keep holding the answer button, and press and hold the volume + button for another 5 sec. until the blue light comes on solid.

sorry - i posted my response at the original thread : )

Definitely it is not your computer. When it was given the signal to go OFF, it did but like completely off.

check your warranty with that monitor and exercise it.

Yep u got it ! warranty or new monitor

I was told by the repair service to unplug the power cord for about 5min. This resets the internal computer. I think this helps but does not cure the cause. Good luck.

post your model. Sounds like the blue CRT is shorted. But let me know the model and I will let you know how to test it.

Usually this problem is due to the firmware. When the firmware is updated to version 1.62.02, this problem usually will be corrected. The older firmwares have problems in recognizing the battery and allowing the battery to power the unit.

You will need a wall/AC charger for the operation. Plug in the wall charger and USB cable at the same time. Your Zen should power on when connected to direct AC power via the wall charger. Once it is powered on, connect the USB cable to your computer. Then begin the firmware download.

If your Zen does not power on when connected to the wall charger, your unit is dead and its time to replace it or get the motherboard replaced via one of the Repair services offered on this website.

If the upgrade button on the firmware window is not available, it is also time to replace your motherboard due to corruption of a chip on the board.

I have a 56" model that I have had a similar problem. My bulb burned out in <90 days. Warranty was 90 days on the bulb itself. When the TV picture goes out, the indicator LEDS blink on and off.

Here is what you have to determine:

1) First cover the left LED with a piece of paper so that you can't see it blinking. I don't know if your layout is the same as my TV. You may have to switch the paper blocking the LED.

2) Pay attention to the other LED and READ its' flashing code. In my case, the code was 2-3. It would flash 2 times, pause briefly, then flash 3 times. This meant code 23. That indicated the bulb was burned out.

3) If you look in the manual, It does have a code list of some sorts to tell you of the codes and their meanings. Hope this helps.
