IF you have never done it, very complex with the alighnment and software transfer to do, tht is why Hitachi wants folks to have an expert do it, it takes about two to three hours to complete.
I have done a few Hitachi 60V500 LCD light engine replacements. V500 chassis is pre: 55vs69a . The engine comes complete with software installed.
The unit must be almost completely dis-assembled, no exaggeration. The top is removed (screen and mirror) and the engine exposed.
1. The manual tells you how to lift and tilt the engine through the top hole with minimal dis-assembly of the main "engine mounting" frame. If the mounting frame is taken apart and re-assembled, the integrity of the "Factory Mechanical Alignment" is gone.
2. The light engine and the cabinet assembly have numerous interconnect plugs and many tricky plastic parts to initially remove or deal with. Installation and re-assembly must be done in the same order and manner as the initial dis-assembly.
I do not recommend that a rookie try this on their own TV.
If the unit shows a picture after re-assembly it will need mechanical and electrical adjustments. Knowing which adjustments are required and how to do them requires fundamental knowledge of the electronic, mechanical and optical features of the unit.
You are buying a "rebuilt" engine probably. All of the units that had engines replaced because of dead pixels went somewhere.
Find a shop that has techs that have done it before, pay them a reasonable amount and get it done right. (Make sure you buy the engine from them, then the correct operation becomes their problem, not yours.)
I refuse this type of job because of the uncertainty of a satisfactory result and the high probability of time wasting callbacks.

The initial question was How Long?
2 equipped techs with experience = 1.5 hr
1 rookie consumer = 10-20 hours

my bad your right sbout the preinstalled softwarein the hitachi engine., I forgot you were talking sbout hitachi and not the the mitsubishi, as I have done and talk so much about those sets. I forgot you were talking sbout the hitchi light engine, sgsin sorry sbout the preinstalled software confusion
Take plenty of pictures and document your endevour and write and submit sn article here on techlore. If you need a hand with that, I would be happy to co write one with you. Good luck!
im had a hitachi expert look at my tv today. could this yellow tint in middle of screen be from a faulty lcd. im told they are replacing it for free. why are they being so kind to me?
The VS69 series is pretty easy to replace. Pry the middle cover with the Hitachi logo on it under the screen. There are two hidden screws that need to come out to release the front of the engine. Take the back off, remove the metal plate over the AV jacks. Take off the lamp door shroud assembly. Two silver bolts at the back screwed into the bottom hold the rest of the engine in. As you slowly remove the engine you'll be able to figure out what needs to be unplugged to get it all the way out. There are a number of pieces that must be transfered from the old engine to the new. Not hard to figure out. Put it back in, plug it back up and you're done.
