hissing noise will be from high voltage regulator, i would suggest to do following:
1. switch tv off
2. remove plug from the wall
3. using air blower (compressor attachment - not leaf one!) blow the dust, especially from high voltage box section
4. connect the tv and switch on
if tv still issue hissing noise - follow 1 and 2 then:
3. remove back cover
4. use air blower again...
5. re-install back cover
6. reconnect tv and switch on
if hissing noise persist - check for blown capacitors on high voltage, replace if necessary, they have nasty tendency to pop if they are too long in storage, especially if tehy were overheated or frozen.
hope this will help you solve the problem, do not forget to vote...
I think the backlight is failing, you will need to have it replaced. It is also possible that the backlight inverter (power supply) may be faulty but that usually shows up a fault. I think it unlikely that the screen itself has failed unless it has been subjected to pressure damage. I hope I have been of help but please do not hesitate to ask if you have any further questions. I appreciate your vote if you appreciate my reply.
Yes, if lamp has not been replaced in last 2-3 years then it is lamp problem. If tv does not shut down and its standby light does not blink in red then lamp is cause of problem, replace it to fix tv issue.
The main board and or power supply is seeing a problem is shutting down the TV.
The cause for your issue could be the power supply, main board, and or the drive board(s) that drive the plasma screen. Sorry, but to trouble shoot that issue would require some TV tools and knowledge of electronics.
Perhaps the following can help you with a warranty repair.
1. If your TV was purchased from January 1 2008 to today---The TV does have a 1 year warranty on parts/ labor and a 2 year warranty on just the plasma screen.
2. If your TV was purchased before January 1 2008---The TV does have a 2 year warranty on parts/ labor and a 2 year warranty on just the plasma screen.
I hope this information has helped you.
have a toshiba regza 32hl67 LCD tv which is only 2 1/2 years old. The
picture on this unit just started to go the other day (screen darkens
but images are still visible and the motion/movement is very slow). I
contacted Toshiba and they just said to unplug the tv for 3 minutes to
reset the tv. This doesnt work. I am VERY upset with Toshiba, after
paying $800 for a tv that only lasted 2 1/2 years. If anyone has had
similar issues and know how to fix it, please let me know. Thanks
On a tv whether it be projection type, plasma or lcd screen, new or old, 2 1/2 years is sufficient time for dust and lint to accumulate inside the tv and its components. Those lamps are a good place to start. There are external factors like humidity, temperature, and the cooling of that tv that can affect the picture over time. To clean those bulbs/lamps you need to be careful and use a lint free cloth like they sell at Home Depot or Lowes. I call them detail rags because they attract lint and moisture and leaves the surface dry. Also a can of clean compressed air like they sell at Radio Shack or most electronic supply stores can be used to clean the dust and lint accumulation on the components. The cooling fans on those tvs and any for that matter are notorious for bringing into the tv anything that is floating in the air. So I would first blow clean compressed air on all the components you may see dust and lint accumulation even the bulbs before I use the detail rags to take any remaining residue from the lamps. The inside of the screen should be cleaned as well. Be sure for safety to disconnect the power to the tv and to touch the frame of the tv to discharge any static electricity you may be carrying due to carpet floors or other objects so that you do no inadvertently damage a sensitive component. On HD tvs all the components other than those bulbs are static sensitive. Just be aware of that. Should this type of cleaning not improve the quality of the picture then I would have to assume that the voltage from the power supply supplying the voltage to the lamps is getting lower with age. On that I can probably help you depending on what you are comfortable doing with your tv in adjustments if there are any. Let me know and I'll be glad to lead you through it if necessary. Good luck and God bless you. Robert
Dell will replace it if it's less than 3 yrs old but apparently their tech support people are clueless about this and have to be told what they need to look up. The replacement is a nice gesture except if you're like me and paid >$1,000 for this more than 3 yrs ago. I have had TV's > 20 yrs and don't reacall major problems with any.

it could be dust in the mirror or in the optics,in this set if im not mistaken you have acces to the mirror from the back, anywhere from 12-20 screws it sould be easy to remove plastic cover first and the the mirror.this mirror are very delicate you dont want to leave fingr prints on it it will show just like the dust is showing right know. taking the mirror off will also give acces to the lense.
use someting soft to clean it.
