The image seems to reflect the possibility of problems of graphics processor.

Some models had a history of failure or bad solder connections. others may

have a combination of capacitors & other materials; Finally we have to fix.

One of the remedies for a graphics card problem, is a re - weld made by the

users who have taken their card from the computer & their cooked in the kitchen oven.

This idea has worked for some; You may be able to contact an authorized Apple

Service provider or see if any of the parts suppliers in line can answer questions

availability of replacement given to nine graphics cards, if you were

can be removed from the logic board or if it is affixed, or welded to the card.

An iFixit.com repair guide for your series of iMac (Intel-processor 2008) 24 inches

can show that if that article can be virtually eliminated, if if will show process.

The details of the computer in the bottom of your post isn't an iMac G5 model, and

There is no powerPC G5 processor equipped Macs after late vintage

2005 to early 2006; If the computer in the discussion is a G5 is not 24 inches

and would be a model of Intel. They use a different architecture than G5

powerPC even though in some respects are similar at least in the General design.

This contains all guide ifixit for iMac G5 Power repair (there is no 24-inch model)

https://www.iFixit.com/device/iMac_G5

If you have an iMac with Intel processor and an older iMac PowerPC G5, specify.

Don't know if a reset of the SMC or likely to alter the symptoms or change NVRAM

the Visual problem on the screen; an underlying hardware problem is a likely cause.

• Reset the management system (SCM) controller on your Mac - Apple Support

• How to reset the NVRAM on your Mac - Apple Support

If this is your model iMac (24 inch Early 2008) follows the model of generation identifier:

Introduced April 2008

Abandoned March 2009

IMac8, 1 model identifier

Model number A1225

EMC 2211

MB325LL/A order number

First Prize $1 799 (2.8 GHz) $2 199 (3.06 GHz)

You may be able to find the numbers of reference and research for replacement new or repaired

old stock graphics cards. A friend had one of these models of iMac 24 inch 2008 and

It failed due to a graphic processor; where she lived the BestBuy did not fix

She even if it has been purchased by them with their extended warranty; No applecare.

So, there are some out there in almost perfect condition, but not fixed, always.

Do not know if the charges involved would be the value relative to the other

later construction that can have no history of similar design construction. {Confirm the identity of the iMac.}

Sorry I don't have any new ideas regarding this problem.

  • Hello. Does anyone know why a dot on my videos but not my photos? Thank you.

    Hello

    I'm pretty new to DSLRs and I have a strange problem, I hope you pros can help with

    I recently had a canon t3i and use it mainly for video. A small dot (see below, in the yellow circle) has appeared in videos. It is always in the same place and it did not exist before. At first I thought there was something on the lens, but no, and the strange thing is, the point does not appear when I take still pictures, only videos.

    Nobody knows what this could be and how can I get rid of him?

    Very appreciated

    This likely dust on the sensor – don't be not alarmed, it is ordinary and easy to clean.

    There are actually two filters in front of the sensor - then 'dust on the sensor' is really the dust on the filter (nothing can really touch the sensor.)

    Most of the models of rebels have a self-cleaning - mode but it uses a piezoelectric effect vibrates the filter and I hope only to shake loose dust.  He used to always work.

    If this does not work, you have two options... it take a photo shop to clean (some stores may practice you a little money... even if I've heard of places that charge customers $50 - I think that's quite excessive.)  The other option is to clean it yourself.   If you do a lot of photographry, you can learn to do it yourself as well because it is something you will probably need to do from time to time.

    I have levels of aggressiveness that I use to clean a sensor... start by simply using the puffs of air (not very aggressive) and working my way up to the point where if nothing works otherwise, I could have possibly used the wet cleaning (but is almost never necessary.)

    Remove the lens, point the camera down so that the aperture of the lens is facing the ground (or resting on a table).  Turn on the camera, use the menus and select the self-cleaning option.

    See page 184 of your manual.  Basically you press menu, navigate to the #2 yellow key and navigate to "sensor cleaning".  Call the "Clean now" option (you may need to do more than once... but if it is not clear after 2-3 attempts, then the time to move to the next step.)

    By the way, to check if it is clear, put the lens on.  Set the camera to Av mode, compose a value large aperture (f-stop) - say f/16 or f/22.  Now, find a simple white wall (or ceiling) and take a picture.

    It is the sensor dust easy to spot VERY when you have a white non-contraste surface like a white wall or a ceiling AND use a high value of f-stop.

    It is clear, very well.  You are finished.

    If this isn't... next step is to get a hand blower - squeeze - like a Giottos "Rocket Blower.  I do NOT recommend you cans of compressed air.  These boxes will spray a residue (fuel) on the filter if you do not pay attention and then the filter should be cleaned at the wet.

    Access the menu cleaning sensor itself, but instead of "clean now", choose "Manually clean".  This causes the camera to raise the mirror and open the shutter to expose the sensor (really the filter).  Keep the camera pointed down and apply several puffs of air into the camera.  DO NOT let the tip of the fan touched anything inside the camera (otherwise you can mark or scratch the filter and make things worse.)

    If that is not ALWAYS clean, I use a magnifying glass to inspect the sensor to see what I'm working with.  You can buy these brands such as "Sensor scope" and they are inexpensive.

    My next step is to try a VERY soft brush to see if he brushing.  Use without pressure... just a few features very soft and very light should do.

    If none of this works, then it's time for the wet cleaning.

    Buy brand Eclipse cleaning solution (made by "Photographic Solutions, Inc." and transported in more real camera stores (not department stores that sell cameras).  You can also order online.

    You will also need the right size, cleaning swab.  This same company (Photographic Solutions) makes "Sensor swabs" but they come in sizes to fit your sensor.  For cameras with sensors APS - C size (which is what you have), you want a buffer of size of Type 2 sensor.

    OK... the purpose of this next step is do NOT damage your camera buy waste of money (not... "I'm not kidding actually.)

    You will place about 2 drops of Eclipse solution on the end of the cleaning swab.  You use the swab to sweep from one side to another sensor using almost no pressure.  Eclipse is almost pure methanol, evaporates quickly and leaves no residue.

    You will now be IMMEDIATELY discard this swab.  (this is what I mean about the bit 'wasting money').   There are 12 buffers in a box.  You can use a couple of them to clean the sensor.  They are cheap.  Your camera is not.  Do NOT try to save money on cheap disposable pads and risk damaging your camera - because if this swab picked up a little sand, would you scrape little sand on the sensor by reusing the it.  That's why I suggest using almost no pressure AND why I suggest to use the scope of the sensor to inspect the sensor and see what I'm working with.

    A sensor cleaning is not difficult, and if done right, it is not even dangerous.  But if you take anything to him as you have been cleaning a window, then you could make things worse (and potentially expensive to correct.)  Just go slowly.  Inspect everything.  I ran with the assumption that all which is on the sensor will scratch if I do not pay attention (even if most of the time this isn't true) and very light pressure allows to "tease" the offending bit of dust on the sensor.

    When you are finished, simply turn your unit on and put the lens on.  It automatically closes the shutter when you press the power switch.

  • Does anyone know why Itunes creates two categories of artist? (Photo inside)

    as you can see in the picture? his is not under the same artist, and I don't know why.

    Show your musical using the songs view library, so that you see a simple list with columns.  If you do not see the column Album artist , show it (right click on the header row in the list of songs to hide and show columns).  You can move the columns on the list by dragging the column (right or left) of its position.  I put the Album artist artist column column.  Make sure that the entries in the Album artist for all songs from this artist have the exact same entry.

    NOTE: You can do this at once by selecting all the songs of the artist and do a read the information on the selection.  Change Album artist in the Details tab for the Info field.
