I'm glad I found this thread, although now I'm even more frustrated that this is happening. Like others have reported here, I've had my Pavilion A6300F since late February 2008---just past the two year mark (and if you consider that I was out of the country for two months during that time, then it's only been used for exactly two years!!!)
Today, I was online at TripAdvisor.com when my computer all of a sudden showed a blue screen and then shut off. It went back on briefly once and then nothing. Like everyone else is reporting, I hear the hard disk spinning, hear the fan running, and the DVD drive starts up, but my monitor says it is not receiving video input. I've tried resetting the CMOS and removing the lithium battery on the motherboard for five minutes. I checked all of the connections and everything is secure.
I'm really annoyed. I have been a loyal user of HP computers for the past several years and have always recommended them to family members. In my searches across the internet, it seems like this particular model is failing consistently right around the two year mark. While I'm generally comfortable installing hardware on a computer, I've never replaced a motherboard and am not sure if I feel comfortable doing it myself. If anyone has any tips, I'd love to hear them. Otherwise, I will be buying another computer and it certainly will not be another HP.

Well looks like I am in the same boad the the Pavilion A6300F Monitor not working. I got this pc from a friend who said it would come on but keep getting message "monitor not connected". I new that it would be a simple problem or a complex one. I have read the other posts here and see there seems to be a problem with the pc motherboard being defective. One thing I did notice is that the video connection for the monitor is not a very well made connection. Considering how stiff a monitor cord is, the connectin is only supported (physically) by the motherboard itself, thus making it easy to damage if the cord gets moved or snatched. Also noticed like a little connection switch at the base of the plug to the metal wall of the machine, like some sort of ground. If you pull back on it with monitor cable connected, it will make contact as though closing a switch as though this is some type of safety switch or something.
However even after connecting an moving in several directions and making sure the 2 little metal tabs are touching the plug, still nothing.

Yes, the a6300f motherboard is a real dud and seems to die with a very high failure rate right around the 2 year old mark. Unlike more commonly failed components such as disk drives, CD/DVD drives, video cards, etc, the MB is not easily replaced and can require an OS re-install (and possible loss of data if you cannot get it backed up in advance). You would probably need to re-install all of your programs (which in my case will be very difficult and time consuming). In addition to this forum/thread, there are many other references to these problems, not to mention the high percent of users who just call HP and either pay them for a replacement/upgrade or scrap the computer and never buy another HP.
I have bought HP computers for many years. I am an electrical engineer who has worked in the computer industry for 25 years I am am highly confident that this is a MB failure due to a defective part. I would like to see HP admit that this is a high-failure-rate component and either compensate all buyers or replace with a different MB for free (goodwill extended warrantee). I am sure that many of you have also paid extra to buy HP workstations over other brands due to their reputation for quality. I feel they have a significant reputation to protect and they will undoubtedly lose more money by losing each of us and our acquaintances as future customers for decades. I am frequently consulted by my friends on which computer to buy and I will not recommend an HP if I lose faith in their quality and willingness to stand behind their product. BTW, here are some other URLs that reference this same problem...

Yep, 2 years exactly the same problem. Seems disapointing that HP are not responding to the issue on the forum.
Thank you for previous comments at least gives some direction regarding the issue.

Thank You!!! to ChucksComputers you saved my HP A6300F computer.
I followed what you said and installed the Intel DG43GT motherboard and my computer is back to life using all of my original hardware, hard drive and OS. The computer did have to do some self diagnostics and a few reboots before it was totally up and running. Once everything was back to life I had to spend some time loading the new driver software and reconfigure the video settings ect... but that was much easier and far less expensive than setting up a new OS, hard drive and such.
So anyone else out there having the same motherboard failure this fix works and I did it myself. I would consider myself at an intermediate level when it comes to this sorta computer stuff, no formal training just previous hands on experience.
BTW: I got my board from TigerDirect for $79.99 + S&H w/ expedited shipping it was here in a couple days.

I also had this problem on my 1 1/2 year old a6300f and replaced the motherboard with an ECS G41T-M2 Gold (V1.0) from NewEgg. Unfortunately, when the motherboard went bad it allowed me to boot several times followed by a variety of crashes before it went to no video. After replacing the motherboard I was unable to boot to Vista possibly due to corruption caused by the crashes so I had to try a system recovery. Well, system recovery either from the D:\ partition or from previously created Recovery DVDs don't work because of the motherboard tattoo. After many attempts somehow I happened to hit a certain sequence that allowed me to access System Recovery and recover the OS. However, just before getting the desktop prepared I got the dreaded "Code Purple" error. Fortunately there is information on the internet on how to get around this so I finally completed the install. It's a real shame that HP has not offered to replace these flawed motherboards. I know that HP representatives monitor this forum and I urge them to scalate this issue with management. During recent years HP's reputation has suffered due to support inadequacies and ignoring the number of viewings that this thread has received will further contribute to this negative view. A little good will on HP's part could go a long way in restoring credibility and help prove that HP's "Total Care" is not just a logo but a reality.

I have somewhat the same problem I have A dell 31 inch monitor when the computer is turned on you can hear the computer booting up but the screen is blank after using the remote I turn the monitor off and while turning it back on I hold the button down for forty or fifty seconds some it turns on the screen but most of the time it takes three or four try's to turn on the monitor.

hi I just got a 2nd hand HP dc5750 SFF PC - however on startup the monitor returns a 'no signal' like above. The monitor works fine on my existing pc so it's not that. I am connecting thru the monitor plug not the DVI - any thoughts??
