Question about Optoma H30 Multimedia Projector

1 Answer

Optoma h57 purple tint

I am Anastasios from greece and I own a Themescene H57 dlp projector (Serial no. T81D444AAAAAA1148) which I bought secondhand with brand new lamp and I have the following problem: The projector after only 20 hrs on the lamp emits an horizontal purple tint in about 50% of the projected area which moves up and down periodically plus the picture gets bent and distorted especially on the left side(projector is ceiling mounted).On the backgroung the picture is detailed as ever and on startup before it locks to a source (i.e with no input signal)the projection appears normal. I haven't dropped it or exposed it to any extreme conditions.It started doing that for no apparent reason. I'm using component and s-video inputs.There is no unusual vibration when projector is on.The colourwheel on visual inspection is intact.Could be a fault with input board or the main motherboard? I'm suspecting the horrible flactuations on the household voltage of our national supplier is to blame which is only good for kettles and deep fryers and not delicate electronics.Can I do something at all to rectify the problem? If I need to have the boards replaced is there a service center in Greece help me?
I would greatly appreciate any technical input/thoughts /suggestions.Many thanks in advance

    Thank you for your reply

    I've tried connecting the projector digitally using a dvi-d cable and works perfectly now.The problem remains for analog signals. I am happy but a new dvd player with hdmi aoutput is already on order.

    P.S. I've sent a very similar email to the Optoma custmer care centre in the US and all I got back was: "the warranty is not tranferable,for pricing etc refer to.....bla bla bla". They refused to sell me a mainboard when I asked them to.LEC Hellas were a bit more sympathetic to my problem and refered me to ADAMCO. What they told was that all they do is sent the projector to the UK to be repaired for a minimum of 180 euros to cover only postage costs. Fair, but that's all. The lesson here is that if you are in Greece and your out-of-warranty Optoma projector develops a problem you're all alone or taken advantage of.That's my personal experience.

    Its hard to give an accurate diagnostic without actually inspecting the unit, but it sounds like a video chip issue. So your on the right track by suspecting the main board, try,,

    I've experienced similar issues obtaining parts from Optoma, if you cannot find the main board at one of these resources, I would try to find another used one to swap parts

My optoma projector has a green tint

it may just need a service, as all DLP projectors need to be cleaned internally as well as LCD.
DLP projector images will flicker and lose colour also may shut down if it is very dusty inside.

My optoma projecter has recently started flashing purple about every 5 seconds. Any suggestions about what the problem could be?

Its an indication that your color wheel is loosing synchronization once in a while.
How old is it and are you out of warranty ?. You will need professional help to get this sorted out.

Ive just bought a new bulb for my projector (Optoma HD700X DLP Projector), taken the old one out and screwed this one in, but im still getting a read light when i turn it on, it sounds like it is...

if replacement lamp has done, was the lamp timer reset after replacement? and if the lamp is original, there is either a bad lamp or a cooling problem.
Good luck
