Is this definitely the bulb on projector?

Thanks, found this one http://www.chsinteractive.co.uk/ele...arized-out-b-for-optical-unit-b-panasonic.htm doesn't look blue...or am I being stupid?

I have been looking online and people say a cheap way to fix could be using a polariser from a calculator screen...is this correct or does it have to be a blue filter? Trying to understand the whole process and how it works.

I feel like the angel of doom here because all I seem to be is delivering bad news.

There are two polarisers. The one you see on the bracket is the incidence polarizer. This is the one that the light passes through first before it hits the LCD panel. That will need to be replaced.

The second polarizer is after the light has passed through the LCD panel. This is the output polarizer. That;s the one that just looks like a piece of glass. It's glued to the optical block (that cube with the ribbon cables). This will also need to be replaced.

What I would suggest is that you disassemble the LCD panel and glass polarizer from the block. What you're looking for is any signs of heat damage on the LCD panel itself. Replacing two polarizers will be expensive enough. Replacing a shot LCD panel as well might well make the whole thing uneconomical for what is just a 720p projector at the end of the day.

Don't remove the incidence polarizer until you have marked the position!!!!!

The new incidence polarizer needs to go in the same position as the old one. The position is adjustable. If you get the new one's position wrong then the picture will look odd.

You do seem to be the angel of doom here!

I think its more nostalgic rather than anything and appreciate the fact it is a 720p, if there was any cheap hack to fix it I would hae done this for the time being.

It may be I can use this to my advantage to twist the wifes arm to allow me to even just go second hand off AV forums...I am sure that is what my Grandad would have wanted!!

Would a Optoma HD65 be a good cheap alternative? One up for sale for £150...probabally offer a cheeky £120. Has 533 hours usage.

It's a shame about the Panasonic, but if it's going to cost £150+ in parts plus a new lamp then the Optoma does look a better deal.
