It is a high pitched sound that could be described as fan like but not the fan, or a grinding sound from that area?

that buzzing is the high end power trying to turn the lamp on.... the electrical current and shock is what turn your lamp on your tv which is what the buzzing is dont worry thats normal...however your solution is buy a new lamp for your tv but make sure its the right serial number for lamp u cant just buy any lamp. best place to buy one ebay.... as in the lamp still trying to light up its only because the electrical current going into the lamp and then cutting off causing the red light on your tv....so other words all it is is the lamp... CAUTION!!!! those lamps get up to 400 degrees unplug tv to ensure no electrical current.... hope i helped.... JACOB WINKLER

Good picture. You have a board going out inside your light engine. Unfortunatly it cannot be replaced. However you can contact Toshiba. They will mail you a box that you can put your light engine in and ship it back to them. They will fix it and ship it back to you. This will cost a few hundred dollars though.

Hi Shirley.As said in the previous comment the problem is convergence. Usually the two convergence ICs must be replaced. The part is not expensive but there is some labor involved in replacement. The repair is usually charged between $150 and $200.

hi; you need to replace the lamp of your projection tv.
these could help you.

Reset the lamp hour meter. Unplug the unit in the main power outlet then turn on the main power switch on. Press and hold the ON, stand by, menu and Input buttons at the same time the buttons are on the projector. Though the same buttons are found on the remote control, the reset only works with the projectors buttons.Plug the power cord back in to the outlet while holding the buttons ON, STANDBY, MENU, INPUTS buttons at the same time, the lamp timer will reset when the projector receive power. Good day and best regards.

Some of these sets had a stupid feature. In the customer menu look for something called quick start.

The way you can tell if it is engaged is when you turn the set off the lamp dims but does not go out and the fans stay on all the time, clearly this feature was meant to speed up the turn on time but with it engaged when you turn the set off the lamp is still hot, if you turn it off and try to turn back on it will not function for fifteen or twenty minutes.

If you get the set to come on watch the lamp from the back and then turn the set off, does the lamp just dim down or go off? Lamp fan should run for a maximum of five minutes to cool lamp off, if it does not shut off and lamp only dims down look in the customer menu for quick start and deselect it, it is DEFAULT setting if set was unplugged.

These sets with this feature had problems where the lamp did not last two years.

Before you rate this solution let me know if you find what I described.

Check the lamp. The sound you hear is the spark gap on the ballast that strikes the lamp at startup. The lamp access door is on the side or rear. The cost of the lamp can be upwards of $250 and cheaper online but recommend the OEM replacement, no knock offs.

Try website like YouTube.com type in ur tv model and make will have somebody doing a colors wheel replacement and have tutoring video for u to follow.

Hi! Did you ever get a solution for your Toshiba problem?? I am having the same problem but can't seem to find an answer. HELP!!!

Yes,have a philip screw driver,just take the back cover off.Find the fan,unscrew like four screws,disconect the input connector.Should take out the fan out easily,replace it.Tries websites like Partstore.com,Ebay.com to buy a new fan.

U get a channel numder and menu screen do show up?Not the tv,it the incomming broadcasting signal cable plug in or the cable box itself have problems.Tries unplug,replug the tv and the cable box back in like about an hour later.The tv will reset itself to the factory setting and the cable box should upgraded it softwares.Should work now.If have the same problems,tell the cable company change the cable box or check the incomming broadcasting cable wire with another tv,see the incomming broadcasting signal cable wire,with a new cable box,see if it work.

U hearing alot of clickings,when the tv turn on?Yes,the board call the Ballast board is dead also.This Ballast board,job is to help, to ignite the projection lamp.Tries websites like Partstore.com,Ebay.com to buy a new Ballast board for the replacement.

Reports indicate the color wheel is sealed in the light engine and MAY NOT BE AVAILABLE AS A SEPARATE PART.

You can contact either Andrews Electronics (LA and largest OEM parts dealer in USA---some of these sets do not sell it as a part--have to buy the entire light engine which is more than the set is worth as a used set.

Google the model number with color wheel after it and you will see what I am talking about.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

Hi
It sounds lamp is defective in your tv that needs to be replaced.
If lamp in tv has not been replace in last 2-3 years then replace it as it got broke or became dead and causing problem.
Lamp replacement procedure is easy and would be written in tv user manual. Required Lamp is available HERE, click for price info.
Hope these info will help you.
Thanks.

hello When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for
the picture to appear on-screen. See "IMPORTANT NOTICE ABOUT HOT LAMP R
When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for the picture to appear on-screen
in the following situations:
• When the Quick Restart™ feature is set to OFF and you turn the TV off and then on again within a few minutes.
• If the TV is on when a short-term power failure, power surge, or other similar power failure occurs, such that the TV loses and regains
power within a few minutes.
This is a property of DLP TV lamp technology and is NOT a sign of malfunction.
If this occurs, the green LED on the TV front panel will blink (and the red LED will be lit solid) until the TV is finished restarting the lamp
and the normal picture appears. If BOTH green and red LEDs are blinking at a one-second rate, you will need to turn the TV off and then
on again to restart the lamp.
ESTART" on page 8. if this no good check the lamp in side to see if it's not burn't out good luck

Hi,If it seems you are experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.I found it with complete light engine assembly here: http://www.discount-merchant.com/TOSHIBA-2973026206-p/1160068.htm?Click=48173

hello, If you can turn it back on with the s momentary key or power button:
When it shuts off, do you need to push the power button once or twice to get it back on? Also, does anything else about the picture or sound change as it warms up?
If once, then the controller is shutting the TV down either as a result of a (thermally induced) fault in the controller or it sensing some other problem. Monitoring the voltage on the relay coil (assuming these is one) could help determine what is happening. The controller thinks it is in charge.
If twice, then the power supply is shutting down as the controller still thinks it is on and you are resetting it. A couple of possibilities here would be low voltage or high voltage regulation error (excessive high voltage is sensed and causes shutdown to prevent dangerous X-ray emission). A partially dried up main filter capacitor could also cause a shutdown but there might be other symptoms like hum bars in the picture just before this happened. Clipping a good capacitor across the suspect (with power off!) would confirm or eliminate this possibility.
If it uses a pull-knob (or other hard on/off switch), then this may be like pulling the plug and would reset any abnormal condition. NOTE- It require you opening the back cover of the television. Goodluck
