if all the tubes are lit then i would suspect from what you describe you have alge growth in one or all of you tubes. at the shop we would change the fluid called glycol., i rather involved procedure because once you remove the tubes then have to go through advance setup aligning them. We generally change all the fluid in all tubes although you can change in just one. The blue tends to be the one with the worst fluid problems.

First. Lamps can look ok in the center and still be bad. Install a new lamp since I do not know when you replaced the lamp or if at all. Turn on the set and at the same time look through the Lamp Door vent slots to see if the lamp Illuminates. If so your lamp is ok and the Color Wheel is bad.

That most probably seems to be a future issue with your color wheel, it's starting to go out, you need to identify which one you have before you purchase one, there are two kinds, one with a gold bearing and another one with a silver bearing

When a TV is showing vertical colored lines, a loose wire cable in the TV might be the cause. If you knock on the back of the TV, the vertical colored lines MAY disappear temporarily. This is a sign that a cable is loose or the T-Con board is faulty.
A black screen could just be a sign that the TV is turned off, although if it is producing sound then you know that's not the case. When your TV has a black screen even when it's on, it's quite possible it could actually be your external device and not your TV.

You seem to have solved the issue yourself!

If the Backlight issue has been resolved and you are sure they are not the issue then if the diffuser screens have been replaced in a different order or reversed then this is the problem!

To resolve it you should dismantle the TV and rearrange the diffuser screens and test before re-assembling the TV.

When the LED backlights fail on the screen, the power supply shuts down to avoid an overload. You can replace the strips or if you are really motivated and have the equipment, you can test each LED and replace them individually.
