I was given a 54" Akai model # PT5492S today.......it is an 02 model, it has been in our facility's break room since late 02 or early 03...it has pretty much been on 24/7 for over 5 years.....it powers on and has a clear video and audio

I have used the search function but have found very little about AKAI's here and nothing similar to mine

best description of issues:

it has a dark/faded picture(darker arond the edges)

colors appear "weak/dull"

I found a bulb on ebay for 94.00 but was hoping for some opinions before I invested any money in this tv

Here are some facts you need to know before you start spending money.

This is a CRT based Projection TV.
It does not have "Bulbs"
It does have 3 CRT's. (Picture Tubes) (Red, Green and Blue)
If the Symptom is as you describe, you should first clean the years of dirt off of the CRT Lenses and mirror. If it has never been cleaned your brightness will go up 15~20 %

If the machine has been on as you describe, you will have to replace all three picture tubes and do a major convergence to correct a worn out picture tube symptom if the cleaning does not bring the set to a usable state.

Hope this helps
