Re: blue spot in tv
The blue spot on this is dust on the blue lcd lens. You can not get this off of your lens and you would need to replace the optical engine. Part for this is about 800 dollars and that particular set has to be dismantled from the front. It is a optical engine that takes a little while to do 1+hour and I do these repairs all of the time.

The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.
That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.
Thats caused by a bad optical block. The cost of that repair will almost always be greater than replacing the TV.Thats a very common issue with alot of Sony DLP models which suffered that optical block issue with the blobs of color usually blue or green
Hi,that's an issue with the light engine.Basically there's 3 chips blue,green and red they create the image on the tv ,when they start to fail you'll get those spots all over, mostly in the corners.God bless you!
sounds like you have colour impurity problems caused by a magnetic feild being near the Screen. Fist check for any new magnetic feilds nearby. If there have been no new changes, it may also be a faulty PTC device that automatically degausses the tube. When they fail, you will get problems with impurities by way of coloured spots on the screen.
Try disconnecting the set off at the wall for 30 mins, this will initiates the auto degauss process. If all is ok, the spots will be gone. If not, you will need to have someone handy with a soldering iron that is also familiar with TV repair to replace the PTC for you.
Please rate this solution. Happy to answer any other questions you may have. Cheers.
You said it yourself. You hate this set. My question is why did you bother to spend $900.00 to have it fixed when you could have bought a flat panel plasma or LCD set that would give you a better picture than any rear projections set could. My suggestion is since you hate this TV with a passion it's time to start looking for a new TV.
I know this is probably not the answer you are looking for but I would suggest that spending anymore money on repairs will most likely be a waste of your hard earned cash.
The blue spot is most likely either an alignment problem or a weak projection tube. Both problems will cost you unknown amounts of cash to repair.
Hope this will help to put the proper perspective on your problem.
