HitachiLight engine problem

After being told to change my lamp at a cost of $300, and this did not help I called again and was told to have a service tech look at the TV. Gee, the tv's light engine is bad, imagine this. When calling Hitachi I talked to 3 people and since the tv is 4 years old they will not help. Consumers need to band together as this is a problem with the manufacturer of the light engine since it is a problem with other rear projectors.

    I have the same problem, blue haze on the screen. I was told the parts are not made anymore. Did anyone find out where to get a replacement part. Light Engine/Optical Engine. Its amazing how company's get away with providing defect products and the government refuses to do anything about it. Where can I find the parts.

    I had purchased 2 ton Hitachi Ace Follow Me split AC on19-05-2010 from Utility traders Chandigarh.It was the most expensive AC available in the market.My first year was satisfactory, but my nightmare started the next year after the company representive did the free service.The AC would cool my first floor bedroom like a cooler.We would sweat even with AC and two fans switched on.After complaint several technicians visited my place unable to detect any defect. Finally I was told that there was gas leakage and I got gas refilled at hefty amount.Cooling problem persisted, and now there was ice formation on front panel and unit would stop working altogether.After several complaints they again refilled the gas.By now it was October and the whole problem was put to rest.This year again the nightmare continues, now the compressor has stopped working.After detecting the problem the company technicians have disappeared altogether.I had complained on 30 may 2012 vide comp. no.[protected], send several reminders but to no avail.Suggest any action against such companies to get faulty machine replaced, although I plan to approach consumer forum.These international companies take customers for ride and waste our hard earned money.

    I have a few questions.
    First, do I understand correctly that I must replace the polarizer film on a total of six pieces ? The three polarizers that are mounted to the black plastic frame and the three post polarizers that are mounted with metal clips ?
    Next, do I also need to remove and polish away and burnt spots on the glass diffusers that are in the 'tunnel' that sends light from the bulb to the polarizer doodads ?
    Last, when I order the polarizer sheets, do I need to order more than one sheet ?
    Thanks

    Hi DrSparkie,
    I have the same problem on my TV now. I'm trying to understand the steps you give here but I'm little confuse on steps 3 which is,
    "step three: match the polarization vector of your existing polarizer (where its not burnt) to your new film stock, the vectors are matched when light passes through them both, this MAY be on a 45 degree angle" I'm confuse because its kind of conflicting to the picture you've shown wherein the -45 degrees is very clear, 0 degree is not so clear, and 45 degrees is black. You said on the step3 above that the vectors matched when light passes through but in the picture the light does not passes through on 45 degrees so does it mean that 45 degress in the picture is not the correct match? Since the all lights passes through -45 degrees does it mean that we will cut our polarizer to -45 degrees? I already got a polarizer from the link you've provided and it look likes to me that the 0 degrees is the clearest part and the 45 degrees is the darkest part the same as your picture. Do I cut mine in 0 degrees? Thank you very much, I hope I get lucky like you to successfully repair my 50v500a tv.

    No work, The polarizing film of the Cell, I only get the yellow and blue, but it is not pure red, it seems that the angle is 45 degrees, please wait for polarizing film you're going to send thanks for that, friend. now both been my focus on this, I forgot to mention that also I have a vertical line that is reflected on the screen, which could be the solution to this damage, doc. thanks for the attention paid to this problem.

    no funciono, las películas polarizadas de los celulares, solo me dan color amarillo en un angulo y un color como azulado, pero no consigo el rojo puro, según los ángulos parece que no están a 45 grados de angulo, es necesaria la película que tu me dices, DrSparkie. Gracias por todo.
    te comento tanta ha sido mi concentracion en estas peliculas polarizadas q olvide comentar que tengo una linea vertical muy fina en la pantalla, pregunto cual seria la falla que me esta dando, que tengo que hacer.

    perhaps the ribbon cable sandwiches onto the glass LCD plate, and you accidentally "pulled it out" as opposed to breaking it? then it may be possible to reinstall the ribbon, either way, you'll need to remove the LCD screen from the prism and have a look. what does the LCD end of the ribbon cable look like? torn or does it have gold coloured contacts?

    thank you for your reply .as you can see from the picture the ribbon busted right at the lcd .I am currently looking for junk light engines at local tv repair shops I might have a line on one will just have to wait and see. Ido have one more question when ordering the film do I need to order just one.If I cannot find the parts I need I will junk this out .If you like I would send you the junk engine for parts .this only applies to you for helping so many people with this fix.

    the polarizer comes out by removing one screw in the top of the plastic carrier for the pre-polarizers. the post polarizers require you to remove the metal clips and tweezer out the glass plates. re-installation of the post polarizers requires a wee bit of silicone.

    one of the ribbons BROKE? ewwwwww... is this the one between the circuit board on the right of the tv and the light engine electronics, or between the LCD screen inside the light engine and the light engine electronics? the former may be replaceable (www.digikey.com comes to mind, also mouser) but the ribbon going to the LCD itself probably isnt replaceable because of how it interfaces with the lcd. post a picture and I can evaluate your options, but it sounds grim.

    the film you order should be self-adhesive on one side, it is also crucial that the polarizer films are on the LCD side of the glass, in both cases (the pre-polarizers and post polarizers!).

    make sure you apply the film with a wiping motion in the first pass to prevent air bubbles, otherwise you'll have colour bubbles (a novel idea!).

    finally do make sure that the polarization of the old film and the new film are ALIGNED before removing the old film. cut the new film (after checking which side is adhesive) before removing the old film, check them SEVERAL TIMES. the post polarizers have the opposite (orthogonal technically) polarization vector to the pre polarizers.

    attached is a picture of repaired pre and post polarizer glass+film combos.

    Just another quick question. You might have already answered this and i've just missed it but how do you adhere the polarizer film to the glass? or do you? What did you use for that?

    >como vienen en la misma presentacion o hay que cortarlos
    que debe ser cortado y alineado con los antiguos. también se auto-adhesivo

    the picture is of the light engine running, note to everyone, don't run your tv without all the shields in place, there is a significant ultraviolet light hazard

    so then
    -step one, take the mirror box/screen off... to do this take off the back panel and the front panel of the tv,
    -disconnect all the wiring behind the power switch (hidden by the speaker on the 50v's, remve the two screws holding in the speaker)
    -remove the power switch (2 smaller screws)
    -undo all the screws which hold the mirror box/screen on.
    -get a friend to help you lift the mirrorbox/screen, though at 6'4" (194cm) I can handle the 50v by myself.
    Keep all these screws in a sandwich bag, and put this bag aside. this bag is bag #1, and probably has 30~40 screws in it.

    Alfredo, Yo no hablo español bien, pero mi esposa. Voy a buscarla para que nos ayuden.
    The parts that are damaged are polarizers. The parts you identified (espejos dichroic - Dichoric mirrors) are strong, and should not burn. Please look at the picture I have attached for more information.

    Allright, lets put this 45 degree issue to rest. Look at the pictures I've attached, note the orientation (out of plane axis rotation) of the polarizer film, with the post it note attached. Remember here that the lcd screen which is providing the light is providing POLARIZED light, which is why the magic you see occurs. the final image demonstrates the variation in transmissivity as a function of angle of the polarization mismatch.

    This example you will repeat yourself when you are repairing your own films, it's really quite fun.
