How old is that TV?

Order from here:
http://www.samsungparts.com

and specifically:
http://www.samsungparts.com/part_detail.asp?catalog%5Fname=Parts+and+Accessories&product%5Fid=BP67-00227D&search%5Fmodel=HCR4755W

Wow! I think that's a rear projection TV, so it may be time for a new one!, as the part is about $175 + shipping, + installation + your time, + they break pretty easily.

Good luck.

Crack and hole in the screen...


There are several parts distributors in the US that supply parts for Hitachi TV's You can try Herman Electronics, Tritronics and PAC parts, all have websites. Be prepared for the cost: a new screen will be in the $300-$400 range. It's not just a piece of ordinary plastic; it's actually two pieces of specially designed plastic designed to disperse the light evenly, called a lenticular and a fresnel.

Cracked screen


The lenticular and fresnal screen for that unit are sold together under RCA p/n# 258513 and are available from Vance Baldwin for about $260.00 plus shipping.. They make for an oversized item so the shipping is probably 70% of the part cost.

Toshiba 50a60 cracked screen


i have just experienced the same myself, what you need to do is find a tv the same size, it doesnt have to be the from the same manufacturer, although it helps if you can get the same, as all lenticulars do the same job.

The outer screen is called the Lenticular, and the inner is called the fresnal, depending how bad your lenticular is cracked will determine if your fresnal has gone also, the only real way of knowing is when you take it apart to change it, (Dead Easy).

they are quite close together, but dont be afraid of trying, i have never changed one before, but i did it in about forty minutes and i dont know the first thing about tvs and now it is as new.

to change it, all you have to do is unscrew the front of your tv, from the surrounding screws at the back of it, once you have done this there are four or five small screws that hold the front of it up, take these out and your front will come off complete with lenticular and fresnal.

place it face down on a soft surface, so as that you are looking out of the inside of your screen, and you will see the fresnal.

they are held together with four brackets, one on each side of the screen.

unscrew the brackets, and take the fresnal off, then the lenticular.

put your new lenticular in, then the fresnal on top of that, and then secure it together again by screwing the four brackets back on.

it really is that simple, do not let these TV repairmen, scare you into buying a screen from them and charge you an extortionate amount of money to fit it.

im not sure if plexiglass will work, i was quoted £160+VAT for my screen from Toshiba, so what i did, i went on Ebay and found a full tv that was for spares or repairs, and paid £26 for it, and it is just as it was before.

One thing you must not do when attemting to change it, and that is to be scared of attempting it, because once you have done it, and at a fraction of the cost, you like me will curse the people who make a living out of overcharging people for such an easy job!!!!


Good Luck, and hope this has helped..
