Thanks for confirming that the $ on the six yr old set was less than $500.
Always been leery of projection sets. Going to look at it tomorrow. Since your more of an expert than me, would you buy this? If so, anything I should look for? Thanks, jan

Re: Hitachi rear projection
If it is in EXCELLENT shape, 500 is not too much, but I would only offer 400 or 450. Hitachis seem to be pretty solid units. Ask if they have had any work done to the tv when you pick it up so you can know what to expect.

This is what you're going to do, Turn on the Tv and go to the service manual, if the green tint is still there, you have a defective dmd board, but if it's no there, then you have an issue with your video board
did you replace the six convergence resistors with the ICs? as Hitachi recommends replacing the six resistors when the ICs are replaced as the old ICs can harm the resistors and they will need replacement.
I love your model, out of all the sets i work on i would say to keep it as long as you can. You have a simple convergence problem and its not to bad of a repair even at the DIY level. The new sets on the market these days brake about every 10months so to keep your 8 year old tv would be a smart choice. If you can solder and use a meter we can fix your set for under $100. If you call a repairman to fix it its going to run you $300-$500 depending on your area. But even at that its less than 1/4 the price of a quality new set. Remember when you buy a new set these days you dont only have to buy the tv you have to buy a stand to put it on or a wall mount (then if you mount it on the wall either you need to know how to do it or you will need to pay someone to do it) then i never would buy a new set without an extended warranty, then you have cableing to buy (most likely your going to hook it up hdmi) and so on. To put a brand new 52" tv in your house that i would reccomend after its all said and done your going to be looking anywhere from $2500-$3500. Hope this is the info you were looking for. any more questions, or if you want to try the repair yourself just ask!!
The projection tubes are wearing down. This is a common cause of the decrease of brightness range.
You can call a service man who knows the model of set and has the service manuals. He can go through the set and confirm if the tubes are actualy wearing down or there are failed components. If the tubes are wearing, he can increase the bias setups to the tubes to make them a little less dark. This may not last very long.
If there are failed components he can troubleshoot for them and replace them.
skimo, service manual part number is "SM-PA0131" I doubt you can order the whole module anymore set is 2000 yr model, why do you want to order the whole module any way? Big bucks if it is available, BMW Rider
