Need the three color tubes for my 80 in proscan tv...how much and where can I find them

sounds like the left side of t-con board is failing and theyre cheap to replace approx 15 quid. or psu which is only about 30. worth fixing if the screen is not cracked or broken

I believe they are no longer available. The last tv picture tube was manufactured several years ago. To cross reference you will need the actual part number and a lot of luck running across one laying around in some shop.

Need a little more info,if it is a rear projection then I would have to have it in the shop. Several things can cause this with the three tubes. If not a rear projection then the problem is in the main board. Not much help but it is hard to do voltage checks without the set.

I have a same tv the red light is out but picture is good. I am trying to
fix my red light problem, but if not I would sell the whole tv . send me
a email at [email protected] I well get back to you on
sunday

[1] change CRT base socket with New.
[2] set Focus preeset to seting focus adjest but she is Dengerus becous inside tv very high voltage in on coundition so Seting with nr. thech.
[3] your tv set is sum 5 to 10 year old if posibul your tv tube is week.but "don' t vary" "recharge tube cathod " and posibbal tube is ok .
if not
then
Replace tube with New.
" do not repar or replace spare in tv it your self .

According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

You need a professional to align the convergence. it's a big job if one or more tubes have been replaced.

it sounds like the main power supply. unfortunately spare parts are no longer available for this model

TV repair guy is right. There are three separate tubes inside your tv (red, blue and green) that are set up to project perfectly on top of each other so that their pictures line up exactly. These tv's have shorter lives do to the fact that they are using the same technology as a conventional tv but they have seriously cranked the power up on these things. They run hotter and harder than any other tv out there. I recomend thinking fondly of the happy days that you had with this tv, then giving it a proper burial and upgrading to HD.
