I have an exentia pc,its one of those all-in-one pc and monitor.

its only two months old Obought for 300 quid from a shop with 1 month warranty.now I'm having horrendous problems with the screen intermitently flashing off and then on again.

weird stuff. even weirder I notice it happens,say if I open a browser or program its fine but when I close the browser the screen flicks off for couple of secs then comes back on again...this happens every single time.

sometimes also when I click on start, the same two/three second screen goes off?

other times the screen just goes off for a few secs then comes back on (the gaps in time ca be several minutes or just seconds). sometime there is no regular interval.

obviously I know why the shop were selling them off cheap.but can someone suggest what migh be causing this and maybe a solution? I mean it is odd particularly the closing of the browser every time making it flicker to off?

any help appreciated.
thanks
Al

Coulld be a few things

The first thing that came to mind when opening things, was the PSU, I think that its worth taking a look at that.
The next thing would be the drivers fro all the hardware and flash roms.

The last thing would be cooling and heat. failig that I would say that the invertor is on its way out.

Couple of things to look at:

1) Some of the exentia's have an external monitor port. You can rule-out a LOT of things if you can plug another monitor into the PC and determine if it also blanks at the same time, or if it's only the built-in display that has the problem. The manual (should be available online if you need one) should tell you how to have the output on both monitors at the same time. It may even default to to that status, or it may even have a standard "composite" or "S-video" output you can use with a regular TV. Resolution isn't important here...just whether the display works or not.

If you don't have another monitor or TV, then borrow one. It will save a lot of time and energy with this simple step.

2) Do programs keep running while the screen is "off" or does the entire pc appear to lock-up?
(e.g. it could be going into some form of suspend)
To check this, start a program that takes a long time to finish doing something, invoke the symptom, and then determine if the program got a lot more done in that intervening time, or whether it just resumed where it left off. Alternatively, you can start the Task Monitor, select the "performance" tab, and see how much the screen has moved horizontally while the display was "off". You might want to change the menu option "view>>update speed>>High" to make the horizontal scrolling more apparent.

Hello,

For those of us not up to it teaching level could you help with where this item is located and how we get to it so that we can replace it. If possible could you give us make and model type of your replacement parts so that we could get the same as we know that this works.

This looks as if you have solved a regular occurrence with this machine which as been inbuilt since they began selling it in the UK before they went bust!

P.S>:- and after they went bust and got rid of all the warranties promised to people who bought their products, the same people are now up and running again selling would you believe amongst other items a new version of the exantia?

hi there the memory i used was pc 2700 ddr 333mhz which can be bought off eBay quite cheaply as shops don't tend to stock that sort of memory anymore , but what i suggest is you take the back off your exentia whicj is quite tricky so be very carefull when doing so these things have two inverters and 1 of them as gone which is causing the screen to flick on and off intermitantly, i would suggest you swap them around as that what i did also and the screen as not flickered ouce since , i personally think it only uses 1 of them at a time and not sure why it has two inverters as most tft screens only have one , when you finnally get to the motherboard behind the screen you will see the inverters 1 is located at the top of the screen and one at the bottom and are connected via 3 cables on each which just un plug very easily , i hope this info helps all you guys , kindest regards aj

Hello AJ,

Many thanks for the info, could you advise the process for taking apart the machine, I can see there are 6 screws along left and right hand sides but nothing else other than taking the stand section apart by taking off the stand bolt and nut, any further advice would be appreciated.

Regards

MH

It's not the same people by the way. A company from Bromsgrove (the same that snapped up Carrera when it went bust) bought the leftovers from the administrators (stock, customer data, furniture, etc) and now have licence to manufacture under the name Elonex but are in no way the same people. They decided not to give money away by supporting customers who were not theirs as new owners, and had the right to choose either way. They pass most enquiries from old Elonex plc computer owners onto us at ECW, also known as http://www.elonexparts.com, telno: 020 8202 9065
The exentia is very tricky to take apart and rebuild but we do it day in day out - happy to help anyone on this forum with questions.

Hiya, i've got an exentia with the blinking problem also and have found that changing the ram around, opening the system and the display output (to a tv etc) are 'temporary' solutions and usually (for me anyhow) stop the blinking for a good while.

i am considering getting a new external monitor and using the display via S-Video as that's the only output the machine has. Does anyone know if it's possible to do this (will i need an adapter, do i need a widescreen monitor due to graphics card etc)?

also, i have a good set of instruction with pictures (.pdf file) to open the machine if anyone requires.

cheers

I'm sorry but there is no written version of how to take this machine apart. However, we do repair these using the experience from repairing when working at Elonex.

all you guys that repair the exentia are only posting because you want to repair the pc for a price , and your not exactly cheap so get off this post i'm am genuine and have helped lots of people out on here with dissmantleing the exentia and the inverter faults all u want people to do is send it to so you can charge the near on 200 for a repair and labour when the machine isn't worth that , find advertising your business else where people here ar elooking for advice so they can either do it there selfs or to know what the problem is ,
the intermitant screen going off is mainly caused by the inverters failing guys a temporary fix is to swap them around , but is only temporary
getting in to the exentia is tricky but ill help in talking you through it as much as possible
and as for these idiots if they wanted to help you they would tell you this and explaine where you can get the new inverters at a reasonable price , thanks all

You obviously have a job or source of income from elsewhere. Some of us actually earn our living through computer maintenance industry. Help away......enjoy yourself. We are not hiding any manuals.....we don't have any. If you had rent and salaries to pay, you'd also charge labour and not do things for free. I'd like to know in good faith how long it takes you to take apart an Exentia, replace parts (not psu) and rebuild, and how much per hour you think a company should charge.

acctually self employed i own a company called ajcomputers and have been in the i.t industry for 15 years , the people here want advice not you lot advertising your business for profit , if you want to advertise go elsewhere other wise help poeple in a cost affective way , it's costs nothing to write a few lines on here to help a few people out for free thats what these forums are all about, not for me to try and make money from people specially when theres a credit crunch , as i said before take ya adverts elsewhere
