Depends on what is wrong - which could be something as simple as a bad cable connection leading to to (or from the signal source to any intermediate device which feeds the TV, to something complex and expensive. I would start with checking cables, and if possible do a direct connection from some device (computer, gamebox, Wii, etc) to the TV to see if that works differently - if bypassing an inpuot cable or device solve it, then that is the problem.

Check your owner's manual - black and white blinking may be a self-protection against an inpuot feed going bad, ormay be an error specific response. Also check your status light to see if it if blinking a code or status color - manual should describe the error codes your model uses.

Inside the tv, can vary from dust causing shorting or arcing or localized overheating, to the screen backlighting unit going out (evidently a major complaint with Toshibas), poor soldering in the screen (also a common complaint evidently for Toshiba's), backlighting inverter boing bad or bad ground to it, main control board or video driver board goiong bad, power supply going bad, etc. Just LOTS of possible causes - which might cost from about $75-100 for a TV Repairman to fix on up to potentially more than the TV is worth for normal size (under about 40" range) TV's.

You said Theatre wide TV - those come from as small as 23" or smaller to 57" or larger, so depending on size a repair might or might not be worth it - always check new replacement cost (and realizing worth a bit more than that because will have a new warranty too) in advance so you can compare to repair estimate. Also, if a large unit pay attention to repair tech costs for a housecall or to come take it in versus the hassle or risk of breakage of you taking it to/from the shop.

You should probably also google your model number and see if it is one of the ones which Toshiba has extended the warranty on for screen black and white blinking - some units they have done that, but web search indicates they have also cracked down on free replacements/repairs for that problem, presumnably because so many are going bad that way.

If cable/input check does not solve it, the TV Repair is your Search the List category to find well-rated and reviewed repair techs - if you call with your model number and describe the issue they may be able to give you a preliminary (subject to actual hands-on inspection) cost estimate and/or a probable max cost estimate for you to determine if repair is viable - generally somewhere around 36-40" TV is where repair versus replacement for a bad screen or mother board or power supply is exonomic - smaller TV's generally just buying new at a box store is more economic.
