    Hi, I recently noticed that my Hitachi 42PD5200 had got colour bleed from the speakers. At the right hand side of the screen there was a rather large pink smear. It was very noticable when watching ie:- Cliff Hanger, Vertical Limit, or Stargate, pictures of snow, rock & the desert were a shade of pink. I have since taken the speakers off & have done a screen wipe. My plasma still hasn't recovered properly. The colour bleed is only noticable when doing a screen wipe as the screen goes completely white. Has anyone else had problems like this? How long does it take for the screen to go back to normal?
    Cheers, Neil

    I thought this was only an issue with CRTs...

    i have no idea but i would be sure that it would not be the speakers
    i have never had any problems like that with my 5200 and i have had my rel sat next to it for 6 months
    it could be image retension or srceen burn but could not say

    Hi Neil,

    I've been interested in this 'pink' patches issue for a while. I have even emailed Hitachi a photo of the screen under wipe condition but they say their technical dept cannot see the problem and I should contact my supplier to have a look at it.

    Does yours look like this in Plasmas, effected by magnets?

    Hi Cablechap, I rang Hitachi this afternoon to ask advise & I explained to someone what was happening. She told me that speakers DO affect plasmas in the same way they affect crt's. As my TV is out of warranty (DOP 28/8/04) she advised me to write to Hitachi & ask if I could have any le-way on the guarantee so that I could have a free consultation from an engineer as the set is only 14 months old. Will let you know what happens.
    Cheers, Neil.
    :cool: :cool:

    Neil,

    It's definately there, not sure how to link it though.
    Look at all my posts (not that many), you'll see it then.

    Seems a bit weird that Hitachi's own speakers affect their screen?
    Mine are large, as big as a small sub with no shielding and so I would not be surprised. This question has been asked before and all experts say 'no affect from magnets'

    My guarantee is also up - bought June 2004, but I did report the problem via email to Hitachi well within the 12 months, so should get sorted as well.

    Cheers,

    Cablechap

    Hi Neil,

    I had the same problem with my Hitachi 42pd5200 and I never attatched the speakers ever, since I bought it. I don't want to offend any hitachi owners out there but I sold mine cause the picture quality on 90 % of dvds was very average . Occassionaly on daylight scenes it would look good otherwise average at best. I owned it for ! year and never enjoyed watching it.

    I calibrated it as much as I could do get rid of some of the problems I experienced-but no success. Ended up selling it for £650 [with slight screen burn issues also] I was so fed up with it I didn't care how much I sold it for.

    I purchased a Panasonic 42phd8 [has slight brightness/contrast issues] but dealer is working with Panasonic [japan] to come up with a fix. This is an excellent movie machine for dvd viewing. Very cinematic with good blacks, shadow detail and accurate colour decoder.

    If you can afford to sell it, do so and pick up on of these if you like watching dvd films, but the Hitachi is acceptable for watching lots of tv i.e freeview/sky etc.

    Hop this helps.

    Hi Cablechap, the speakers for the 42PD5200 don't affect the set but other speakers do. That's what the woman at Hitachi told me.
    Ta, Neil.
    Oh, by the way, I've found your picture. Mine's nowhere near as bad as that.

    This is simply wrong. And in any case, 99% of AV speakers are magnetically shielded to get around the CRT problem. My plasma sits between totally unshielded in wall speakers mounted in a wooden cabinet. There are no problems. This is the marvellous thing about technical departments (some are worse than others) This eems to me to be a blatant attempt to blame something other than a product defect, just in case they turn out to be liable.

    All,

    Funny what these tech departments say. Surely if unshielded speaker magnets affected (Hitachi) plasmas, there would be big bold warnings in the instruction manual, but there appears to be nothing written at all. Previously, I had a CRT (29") between them and had to move further apart. My present set up has the speakers slightly lower than the plasma and so one would expect a relatively circular field around each to be evident on the plasma, but the screen has two parallel stripes, so I don't buy the magnet related problem either.

    MAW,

    Off topic, but discussed before re: overscan on Hitachis. I recently used the THX Optimiser R1 and R2 with the circle and two rectangle test, and changed the DVI-D output through 480/576/720/1080 and saw no difference in the positioning of the test image. I would have expected the outer rectangle to vanish from view under the higher upscaled resolution. Can you explain this i.e. does it overscan everything (and so I'm not aware of it) or does it just effect off air transmissions, etc?

    Thanks,
    Cablechap

    Overscan: Some is a good thing, gets rid of edge artefacts. Too much obviously loses you picture. Overscan is dialled in by default. It's adjustable in most resolutions, but not HD ones on Hitachis for some reason. Hitachi claim that 1080i is vertically pixel matched. If so, it's a lucky coincidence I reckon! Lots of screens have this trouble, lack of overscan adjustment, with HD digital video. LG and Pioneer most notably,besides Hitachi.
