Unit has a bad optics block (light engine). Rebuilt engines available for around $350.00. I have seen this sympton several times and I am sure this is the problem.

I have a LCD Rear Projection Hitachi tv (62VS69A) and need to replace the light engine I believe. Will an engine from a 50" or 55" tv work?


No, the optics are set for the specific size of the screen. A 55 or a 50 would leave you with a smaller picture and thats even if electronically they are the same

55 inch hitachi lcd projection tv has yellow and purple blur near the center of the screen


This, sadly is getting to be a very common problem with all Projection LCD TV's
Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses on one of the LCD panels themselves which are all located in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and visually inspecting the lamp itself and the lens that it shines onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly. Have a tech confirm-Get an estimate -Be sure to vote/rate me if this helped Thanks!

My Hitachi LCD rear projection TV has blue color in left corner


It is most likely the tube going out. Find some one to replace the tube if the TV is fairly new other wise it is going to be a trend. One tube now and another.. and so on. Ride it out as long as you can then go for an upgrade

Optical engine


The best thing to do is to call Hitachi and see if they would be able to help with the cost of the repairs because it will be expensive.
Hope this helps,

Dark picture on wega lcd


Yes, if this TV has a bulb it is likely to be the bulb.

I am not familiar with this exact model, but other LCD Projection TV will show dim picture after some time. Expected life of the lamps is about 2yrs. After 2yrs the picture will become dim. After 5yrs I am suprised it is even working.

Dirt doesn't cause this problem unless your are a smoker or have the unit "literally" outside. DO NOT try to clean it or let someone tell you to do it because it will cause more problems than it fixes.

TV wont stay on


Sounds like a short somewhere in there. I see old pre-HD big screen sets going for well under $200 on my local craigslist, so look there for a good replacement, because the repair will cost more.

Or fork over about $500 for a good used HD projection set.

Hitachi 52 projection tv


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
