On a scale of 1 to 10, 10 being the hardest: 9. This is the heart of the TV. You will need to make several adjustments to the TV once you reassemble the TV, most time consuming will be the convergence adjustments. This can take hours just to learn about. I hope this was helpful, best wishes.

Some possible reasons include: New lamp is generic and or has a issue----excessive dust or dirt inside the unit on fans etc.

Some of these units had a feature in the menu for quick on where lamp is lit at low level all the time---this shortens the life of the lamp etc

If you did not have this issue before lamp replaced I would suspect a generic cheap bulb may have been used instead of the Toshiba cartridge / lamp combo which costs more.

With the quick on if the set has it normal time is 20 seconds for screen to light----set WILL DETECT IF LAMP IS NOT COMING UP FAST ENOUGH OR BRIGHT ENOUGH.

Generic lamps (cheap) will never be as bright or last a long as a OEM lamp unit.

Just some thoughts based on your question.

Have to start at the beginning---Lamp? Ballast? Color wheel?

I have a Toshiba 51h83. Everything works fine except there is an issue where the colors are slightly lighter on both the left and right sides of the screen.


this is normal with rear projection tv's its from long usage when the tv isnt always in full screen mode. you can sometimes fix this by replacing the bulb/ or the color board for the projector. also you can replace the screen as it seems like it may also be do to image burn in if it wasnt always in full screen mode. (did this for my uncles Mitsubishi projection tv)

let me know if that helps!

No video, sound only. Not moved or anything, just picture stopped.


I am not familiar with your TV, but I might be able to help. Sounds like the lamp blew! These lamps only last about 4 to 5 thousand hours. There should be a lamp access on the back of your TV. unplug your TV and remove the lamp housing and inspect the bulb. Be sure not to touch the lens. If it is blown, replace with a new one!

I have a Toshiba Rear Projection 51H83 & I think the lamp needs to be replaced. I was trying to find the lamp part number & how hard it is to replace.

Tv goes off after about 5 seconds


Bulb replacement is a good try, I would also have them come out to look at the set again as I am sure there is some kind of warranty on the parts.

Lamps burned every 6-9 months.


This is indeed a very common problem with the Toshiba products. The reason I asked about the time is that the television bulbs are estimated to last on average 4,000 viewed hours, which you are only coming up short of 50%.

Toshiba is offering an extended warranty free on the product that does cover the bulb replacement.
http://www.tacp.toshiba.com/tacpassets-images/notices/dlplamp.asp
is the link for this extended warranty.

After researching your particular make and model, I have found that the average span for a bulb is indeed 9-12 months. Beyond this extended warrant, Toshiba is offering no further assistance, and will only replace it once. They have also been having issues with the color wheel going out at an average cost of $750.00 which under warranty they will replace one time only.

There is nothing you can do beyond replacing the lamps, however my suggestion would be to replace the television itself, and stay away from Toshiba.

Color quality


The lamps may not be the problem; it would be highly unusual for two of them to fail at the same time.

I don't think (unless it is a familiar problem to someone here) that you will find a good answer here.
It sounds more like a house call for a tech.
Sorry -

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
