I have read the other posts for this issue without success. I am trying to connect my windows HP Pavilion N5425 to display pictures on my Mitsubishi TV with a monster cable connection. I did it years ago so I know it is possible but don't remember how I did it. When I try hitting FN + f5 nothing happens on the screen. I have the monster cable connected to the video jack on the tv and swiched the input appropriately. I did see one reply about checking/changing the bios on the TV but no reponse. If that is the suggested solution, how do I do that with my TV? Thanks, Jay

The first thing to check is for proper power. Try connecting your charger with the battery removed and powering up the computer. If you are not successful with this, it may be that the charger is defective and not charging your battery. Advise that you purchase/borrow a supported laptop charger. A local HP repair center should have a compatible charger that you could use to test. If it is not the charger (the laptop should work without a battery), then you have motherboard problems. Memory or other issues would cause a power on but errors. No power up at all is going to require some sort of board replacement. At that point, your choice is warranty repair service or, if out of warranty, best bet will be replacement of laptop.
I'm assuming you are connecting the laptop to the plasma screen with an HDMI cable. If you have done so, then have both the TV and laptop turned on. Log into the laptop with an account. After you have logged in, you can press the function key (Fn) and usually its F4 (the key has a picture of a square, this represents the external display connection) at the same time. The plasma tv should display what is on the laptop.
So, Fn + F4 should work.
*** IF YOUR HP LAPTOP IS A "DV" SERIES WITH"GRAPHICS BY NVIDIA" *** (Example - "HP Pavilion dv2000", "dv6000", etc.) PLEASE READ THE FOLLOWING: ALL of the "DV" series have a serious problem due to an inefficientHEAT SINK, which is shared between the video chip & CPU. Video failure is inevitablegiven enough time.
To verify if your Nvidia Graphics Chip has failed, FIRST - takea look at the other solutions postedhere, which are excellent troubleshooting techniques.
You won't see any dimmed video (backlight / inverterproblem) AND you won't get any video by connecting an EXTERNAL DISPLAY either.You will see all the pretty blue lights, but NO VIDEO... nowhere, no how...L
OK - IF THIS IS YOUR PROBLEM, READ ON...
Almost all of these chip failures can be fixed by RE-FLOWINGthe solder connections, both internal to the chip, and external to themotherboard.
THIS PROBLEM IS SO COMMON, that without further ado, I'mgoing to direct you to a couple of YouTube posts (there's TONS of 'em on thisproblem with solutions ranging from ridiculously stupid to way too extravagant& complex for the problem at hand.
LET ME JUST SAY THIS: I've fixed several of these so farwith 100% success just by heating the chip with a small butane torch for short intervals.Don't try to go too fast, just slowly raise the temp to where solder will flow.Using a small pencil torch will give you the precision needed to get the jobdone, WITHOUT all the elaborate shielding techniques that you might see is someof these vids.
CHECK 'EM OUT:
Try updating ALL Video Card & HDMI Drivers from manufacturers web site, that will probably be the best chance at a fix, this is a driver issue. Connect up this way... Start TV... plug in Cable to TV & PC, now, startup PC.
a password just switching on automatically i have not heard before. usually bios passwords have to be turned on and set in the bios. if you are working with a machine that has a system/bios password the only alternative is to contact hp and let them assist you. be mindful they will ask for you to verify ownership and possibly even provide a purchase receipt. this is to prevent theft of laptops. if the unit is out of warranty, they may even charge you. in the event this is a windows logon password there is nt password reset software that can allow you to reset the administrators passwords. so...if the password comes on immediately and does not allow you to proceed to windows you need to contact hp. there really is not easy way around the bios password with a laptop.
try connecting an external monitor to the unit. if you get the same or similar issues on the external monitor then you have a GPU issue on the motherboard. It will need to be REFLOWED or replaced. If you do not get the same issue on your external monitor, then you need to replace your LCD. Our shop replaces these LCDs for 140-180 so i imagine you should be able to find something similar in your area!
on your display properties, switch windows to appear on your laptop. and do not connect your LCD when booting your PC. there is an option in display property that says extened your windows to this display... that is your LCD.
