fly-back has a leak im sure with that.try to check the flyback for blue colored current that goes out from it. this causes the noise, if it has then you can use a sealant to seal the leak

The port or cable is going bad

Check for an EXE file in DOWNLOADS folder. Self-extracting files are usually come in EXE flavour, but may have MSI or ZIP extensions as well. Or go to START, in search-box type keywords like TV, Tuner, etc. to see what win explorer digs up. If that fails, plug in your flash drive, go to CMD console, (DOS commands), type CD\ CLS dir/a/s/b'find/i "nameyouwant">flashdrive:\foundit.txt The pipe symbol ' is Shift+\ "nameyouwant" is any text (filename or part of) flashdrive: is the drive letter, eg F: To append to the search result, use two >> arrows. One > arrow will overwrite foundit.txt with current data.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board..

My infocus g300-ww projector turns on and then turns right back off. What could be the problem?

The input is normally selected automatically as the logic switch tries to gates with the input sources scanning to find the signal present to latch ON.
Now if the scanning -searching-does not give a result it is due to the fact that the main processor is doing the job well to instruct the sub logic IC to gate which is not switching on to track the signal that is present at the input source.
The Projector is working well on the output side but the fault seems to be in the source selection. You can disconnect and check to see if the connecting cord of the DVD is working by trying it on the TV. Confirming the DVD signal cord , the fault must be looked in the Main board. The RCA input to the preamp, the switching IC logic must be checked for the possible fault.
You will need a good knowledge of logic gates to check , confirm and replace the faulty component or IC. If you are able trace the track from the RCA input with a signal to see where the signal is cut off. A loop over in this section with a coupling capacitor will give the picture while confirming the faulty device.

If you wish to do this yourself. You MUST get a service manual, before attempting any repair such as this otherwise you will simply end up in a "Pickle" as they say.
See, it is nearly always my professional opinion that one should always get a "Quote" from the manufacturers recommended service center, Infocus in your case, please contact a local or head office and ask for a referral to an Authorised service center. I cannot stress how important that last point is. It is even worth the cost of shipping. You see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace.
