The model listed here has a HYPER board that processes all signal in the set from all inputs and usually in these sets it will begin with the problem being there when first turned on and after several minutes it goes away--gradually it takes longer and longer until it will not go away----Is this what happened to you?

Thats a common issue caused by bad capacitors on the hyper module

Possible screen controls in the set are up too high---if you turn picture and brightness to zero does the screen get full black?

screens set too high would give diagonal faint trace lines in the picture.

These sets also should get a annual cleaning of the lens and sometimes the mirror inside= if this is the case the picture will usually look darker and dull ----this will not affect lines in picture.

the lens are easy to clean but other actions depend on what your response is to the above information.

Good day!!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

It sounds like your lamp is getting close to the end of its lifespan.The lamp is what gives your screen its brightness.With time they start losing this brightness.If you were to wait to replace it till it goes out completely you would have a black screen.You can purchase a quality lamp at discount-merchant.com

If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Problem seems with Blue Picture Tube that gets internal short thus tv shuts down due to lots of current drain.
46H84 is rear projection tv that has three basic color picture tubes (red-green-blue) to generate color picture. Since it is an old model tv so replacement blue picture tube may not be available anymore, so I would recommend not to spend money and time to get it repaired, a new tv would be better.
Hope this will help.

I have the same exact problem...for a few weeks the TV would turn off and the red power light would blink. Then the other day I started having exactly the problem you describe...green screen for a few seconds and then total shutdown.

It is possible that there is a allergy that is growing the blue and green gun, it will not grow in the red gun, and it blocks the video and makes it look dark, on the greenish side. To fix the problem, you have to change the coolant in the guns, and then it will look like new again.
