Question about Hitachi Projection Televisions

Open Question

I have a Hitachi TV Model # SP50W - 120V 60 HZ - the problem is the color - a few weeks ago, all of a suddent the tv colors disappeared and became very bright - no crispness to the picture at all - it's almost like a bulb blew out or something. The color is all reds, yellows, and oranges - they kind of run together and are very shiny and glimmery - my email address is: crp@nashobawinery.com

SOURCE: How long does a lamp/bulb of a Toshiba DLP 46HM95 46 in last?

Your bulb may be blowing because of airflow issues or power cycling issues, first does your outlet get switched off at any point in time? if so you may be killing the bulb before it cools, if you turn the set on/off alot and or restart it after off quickly this could lead to permature bulb failure, if the original lamp was not replaced with a proper lamp to match the ballast it could blow the bulb. If your tv is too near a heat vent or the airflow thru the set is not adequate it could blow the bulb.

Reset tv to factory settings refer to your owners manual. If still no picture attach a DVD or video player and test. If still no pic refer to tech.

SOURCE: 65" Mitsubishi projection tv, my colors are not matching up.

If red or blue will not adjust in some direction--you have a Convergence circuit problem---

This model (WS-65809) uses two of the STK-392-570 Convergence IC's---

Green for a good reason is not adjustable in the customer mode---it is only adjusted for the Geometry or straightness of the picture and then red and blue are adjusted to it.

If you are able to do this repair yourself you can save the set and a lot of money---most shops charge 300-400 for this type of repair in this set.

You can buy both chips for about 14 dollars on Ebay- and I have step by step---start to finish instructions for this repair in this set--they tell also everything you will need to do and what you need.

If you want the instructions let me know---I am not allowed to post MY email here.....but you.....

Not everyone can do this repair---Let me know if you have any questions or need advice----

If you get someone else to do the repair make sure BOTH chips get replaced or the set will have the same problem again in a few months.

Sounds like your TV needs new convergence chips.

Go to this web site.

If you can handle a soldering iron and solder fairly well, then you can do the repair.

Hope this helps.

I have a HITACHI 60in. LCD rear projection tv (model 60v500). I'm getting 2 large oblong red areas in the center of the picture. Is this an adjustment?


Hi,it seems you are experimenting a light engine problem.This is how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo So basically the 3 Lcd chips that create the colors and image is going bad and thats why you get that color discoloration.Contact Hitachi or look for your light engine online.God bless you and your house!
