    I am posting this thread again because have just heard from someone else with the same problem that Sony have quoted him over £1200 for repair, obviously a write off. Have I lost my sony after so little use from it.

    I switched on my Sony projector on Monday & on the blue background
    screen on the top left hand corner was a strange black shape. I thought at
    first it was a dirt blob on the lens/lcd but the shape was quite weird a bit
    like tips of a fern leaf. When I played a film the outline of the shape
    soften and changed to a smeary yellow on white scenes. I bought my hs10 from
    Unbeatable just over 2 years ago and it has done 400ish hours and treated
    with utmost care. It has had a mild form of the lamp bug but I did not send
    it back because it occurred only very occasional.

    I have looked on the net & from reading reports from other hs10 owners it
    seems that it is another stock fault & it is a failed prism block. Now I am
    not sure what to do. From what I can gather it is going to be expensive.
    What I would like to know is :
    Can the prism block be repaired or can I replace it myself (I have changed
    bits on faulty tv's & vcr's in the past).
    Where can I obtain the spares & how much would the prism block be.
    If it has to be repaired by a dealer who is the best company to deal with .
    I went on the Sony support site & they seem to direct you to other agents
    who might or might not handle projectors.
    Is it worth pursuing as a complaint with Sony UK due to the fact that after
    so little use the pj should go so seriously faulty.
    Is it possible to get some sort of part exchange, although I have been put
    off slighty from Sony due to the poor realiabity I would not mind upgrading
    to the hs50.

    Any comments/help on this problem would be greatly appreciated.

    The prism block is the most expensive part of an LCD projector.


    It consists of the 3 LCD panels, their respective polarising filters and the prism itself. The whole block is aligned at the factory and replacing an LCD panel or a polarizing filter is not an end user job.

    A customer of mine recently decided to strip down a Mitsubishi LCD projector to clean the prism block, filters and LCD panels and totally stuffed it when he disturbed the epoxy resin that locked the LCD panels in place.

    Mitsubishi offered him a replacement prism block at trade price (as they had a lot of stock) which was £1000 plus VAT :eek:

    Sale of Goods act indicates a reasonable amount of use from most items - this in most cases is 6 years. You should speak with Unbeatable who your contract is with and clearly state the product requires a repair as it hasnt fulfilled its use under the sale of goods act. If they refuse then take them to court - you will win.

    It's not worth the hassle, use only as a last resort.

    If it were my projector I would instruct my retailer to persue this with Sony...that is usually how things get rersolved.

    Thanks for the advice everyone, it seems that projectors are very vunerable to a very expensive fault. I shall write to Unbeatable & see what they say & I will post it here.
