The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I have the same tv and had it fixed the problem is most likely the power supply a $50.00 part but I suggest you have a repairman do the fix. Total cost should be around $250.00 for labor and parts.Also unplug your tv for over 4 hours then plug it back in to see if it works they call this a hard reset.If this does not work after 4 hours try unplugging it overnight and then try it. That is what I did to use the tv until I got it fixed. The only thing it could be is the convergence circuitv if this is the case it should cost about $400.00

You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck

SOURCE: Toshiba DLP fan noise (52hmx95)

UUUUggggghhhh I have a 1 year old Toshiba 50" DLP rear projection and it had fan noise. It also had a wierd dark spot on the screen that really wasn't on the screen itself. I was taken to a service center and held captive for 2-3 weeks and returned with a new light engine. I thought great! 3 weeks to a month later and bordering on expiration of warranty it starts to make a low screeching sound like a small motor in need of lubricant. The picture jumps all over and resembles a 256 color PC Monitor. The service center comes and picks it up and holds it captive for another 2.5 weeks and says they cannot duplicate the problem. I had even sent them a quicktime movie of it in action.
They drop it off and an hour goes by and off she goes again. Now the longer I leave it on the worse it gets and shuts itself down and sometimes blinks the "light engine" code. Spoke with Toshiba and they are escalating it and should hear back in 3 days... OMG. Kinda off on a tangent, but they do make strange noises.
Did Toshiba get out of the DLP game???

SOURCE: Problem with Toshiba DLP Projection TV Model #52HM84

It is possible the lamps may be defective or that they may be the wrong replacement for this model, as it may have a different wattage setup with the ballast. If you want to try to order the TB25 lamp from a different vendor, you can order the original Toshiba replacement lamp for this model (52HM84) from a major Toshiba parts distributor at the link below:

I have a loud buzzing noise on my Toshiba DLP 46" projection TV. It is not the fan, it works fine. In fact the TV works great and has a good picture. The buzzing used to go away after awhile. Now it...


In some cases the buzz is external. The vibration of the unit may just cause a tray, flat surface, or other surrounding attachments to rattle and buzz. Look for anything that may be loose or laying on or about the TV.

Hi. I have a 2004 52' Flat screen projection TV. For the past couple months, we have turned on our TV and all we hear is sound, but no picture comes up. We thought the bulb was having problems. We ordered...


The buzzing is the ballast arc gap,normal sound. When the tv starts does the lamp start to come on. Can you see any light from the back? Sounds like bad ballast. Unfortunatly this part is no longer available. the light engine will have to be removed and sent to Toshiba to be rebuilt.
