SOURCE: Toshiba DLP fan noise (52hmx95)
i constantly hear complaints about fan noise in dlptvs if you sit in front of your computer you will hear the same noise even in the next room there is no solution to the fan noise problem this product has a huge cage fan and a second and third three inch fans in it.... more than the samsung product it can be noticeable if the tv is on hard surfaces ie wood floors ,inthe corner, glass top etc the vents on the back of the tv allow for proper cooling of the lamp at shutoff so it doesnt shatter the tube its kinda like annealing glass its designed to extend the life of the lamp .... which im sure youve priced call toshiba and tell them your lamp is bad right now and get a new one for an emergency ( warranty if you can do it ) they are also improved this product is known to have short bulb life sometimes the zinging noise you hear is indicative of a bad color wheel in the light engine which would require replacement ( not cheap) toshiba will not piece out the color wheel assembly individually

The beeping noise is usually related to the Horizontal out put transistor or flyback being faulty or one of the coils are loose near the flyback. If you remove the rear cover without touching anything can you tell if the beeping is coming from the large transformer with the red wire coming out of the top or is it coming from a black transistor on a aluminum heat sink.

Two possibiltes. A bad cooling fan or what is known as a color wheel. is this a whining sound. does the colors flicker. a bad fan could have contribited to the bulb going out too. to identify a technician would have to take back of and examine fans and listen

sesshomaru69, Is your tv LCD or Plasma? How old iis it? Is it still covered by Warranty? Your symptom sounds like it could be a power supply problem internal to the set. You will need to have a service tech look at it. Probably the Switch-Mode-Power-Supply has sensed a failure with some other circuit or with itself and goes into what is known as SHUTDOWN mode to save itself from becoming a catastrophic failure. Your best shot will be to have someone look at it.
Zenith has a building somewhere in Lincolnshire, Illinois but they are owned by LG (Lucky Goldstar) Korea. Most likely everything in the tv is from the Far East and assembled in Mexico, but that's just a guess!!! I'm louie12fix on fixya or lmistyrel @ aol.com Bye for now.
