Hi all

I've been an avid reader of this site since i got my F710BT.

I've spent days reading posts comments, trying to find someone else with the same problem as me and some sort of resolution, but i can't.

I've had the 710 for about 2 months working fine, about two weeks ago it would start to boot up and after about 7 secs (still on splash screen) it would go blank and the illiminated button would also turn off (does NOT reboot), i can still here the fan. No matter how many times i pressed the reset button it would not go back. Yes i've tried booting into testmode, but after about 15 secs it again goes blank.

If i leave the car for over 7-8 hours it will then boot up fine, but if i try to reboot i get the same issue as before until i leave it for 7-8 hours.

So leaving it 7-8 hours i managed to get into testmode;

I've flashed a backup from a f700bt, i've deleted those '4 files' on my flash disc and also the contents of the igo save folder as described on this site, none of which make a difference.

The reverse camera is switched off, the hardware & software bypass are fitted.

I've tried all the solutions i can find on here, the only thing i haven't tried is an installation of a different 710 EU backup, because i haven't got one.

All i can think is like some others have mentioned previously it may be a hardware issue.

Sorry it's a long one but wanted to fully explain, any advice greatly appreciated.

Thanks guys.

Sounds like it could be a heat issue maybe stopping it booting up. After a period of time the heat disappears which then allows it to boot. Have you tried unplugging / plugging in the main power connector at the back and checking your power leads. Also if there's a fan inside it must have vents, check that these are clear from dust etc.

Is it still under warranty ? If so I wouldn't even bother messing with it and just go and get it exchanged / repaired.

Steve, It's been taken out all power leads checked, it still has the same problem when it's sat plugged in on my seat, i.e no vents covered, so pretty sure it's not a heating related issue.

It maybe that the fan is working but the fins on the heat sinks are full of fluff. with you describing the 7-8 hour wait this does point to a heat issue. It may also be a component failing and only working when cold.

Is it still under warranty ?

Afraid not i bought it i bought it second hand. Do you think i should get someone to open it up and take a look at these heat sinks?

So today had the unit out and opened it up, it's clean as a whistle, no dust or anything. Thought maybe the processor would be similar to a laptop and need thermal paste so took a look at that, it's not the same, it's kind of a sealed unit.

Also been thinking more about it being a heat problem and i don't think it is as i drive to Devon today (4 hours non stop) with no problems at all. Yet when i arrived i turned the engine off then back on again to check it and after 6 seconds went back to the blank screen with fans whiring.

Back to the drawing board, any ideas guys?
