Try to hook up to external monitor. if it works your screen is bad. If not it could be your GPU. cost of repair from us would be like 70-140 to repair including return shipping.

SOURCE: Won't recognize battery charger

The battery might need to be replaced.  If it works plugged in, but is not charging....it is simply not holding the charge.  I know it seems strange that when it is plugged in without the battery it will not work, but that sometimes is the case.

SOURCE: Screen for hp pavilion dv4000 won't turn on

i would try hooking up an external monitor first.
If you get video display then this would be your CCFL backlight and or inverter and one or both would need to be replaced. if this is the problem, its best to replace them both at the same time.

If you dont get any display at all, then try unplugging the DC power plug and removing the battery. let it sit for a few minutes and then hold down the power button for 10-15 seconds.
Try plugging the DC power plug back into the computer and then try booting.
If it is still doesnt boot, then i would have to suspect motherboard issues.
hope this helps

SOURCE: my notebook will not turn

Thank you for using FixYa

Apparently the batteries are only designed for a one year life cycle unless you have the extra long life battery. Assuming you have tried to reset the computer and even tried to remove the battery and replace it again, HP has more information for you, but it sounds like it may be gone.
Here is the HP site link.

Have you had a issue where you heard a high pitched whine or fan like sound?

Examine the color wheel- can be done with lamp removed--look in the opening the lamp faces---is wheel intact or missing any pieces?

The set will turn lamp on for a instant and then off if it detects wheel not moving at full speed or not at all.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

Should the power light be green or red, when I turn camera on it shows a green light then turns red


Red light indicates that the camera is out of charged., Try to charged your battery for 3-4 hrs if you encounter flashing red on a fully charged battery you need to call kodak 1 800 235 6325 ext 12

You can charged you camera using 5V AC Adaptor or a USB cable taht attached into the computer

I can't turn on my myvu video glasses when it not charging.


You need to charge the glasses for longer perhaps? I got the Shades 301 pair from my girlfriend who never got around to using them. I have it connected to my comp with a usb cord. The little light on the black box controller started off blinking a purple-ish blue, and now it's blinking orange. I think the blue color must mean battery dead, and the blinking orange i figure means it's taking a charge? I'm going to wait and see if it hopefully turns green! Then i'll find out if they'll work with my ipod touch 2nd gen.

No picture or sound, just blinking power light


Hi...I am sorry to say that I had this exact problem. It ended up being the upper and lower panel drives. I contacted Hitachi and even though my unit was out of warranty, they agree to pay for parts. I paid for labor myself, and it cost me $199.95.

Good luck with it...let me know how it turns out for you.

Blank screen, no sound


If ti blinks three times, then it may be an issue with the flyback transformer. It's called "three strikes"...it tries three times to come on, and after that enters a safety shutdown mode to protect the TV. Might need to have a professional shop take a look at it.
