Toshiba 40pw13p projector lamp problems

I recently purchased a Toshiba 40pw13p projection T.V. and am having problems with the crt's (i think thats what you would call them) With top casing and screen off the blue lights up fine, and the other two light up when you first switch on, but the green and red then flicker out. Can anyone give me advice on what is happening, and what I should expect to pay to repair? Please and thanks in advance.

I had the same problem...I took the back panel off the tv and took a small desk fan and mounted it so it would keep the bulb extra cool...IT WORKED! I left it like this for about a week. It shut off only twice after about 4 hours of on time. I then disconected the small white ceramic sensor on the back side of the light. (there is a plug conecting it, just follow the wire to it) It has been about 3 weeks now and I have not had the tv shut off yet. (disclaimer...could start fire from over heating? try at your own risk.) If it works for you buy a new sensor.

NO - - clearly not 140's.... You can upgrade Q751 & Q752 to 150's or 180's which merely have higher amp ratings and thus more reliable.
Also, make really sure that the "seller" you got these from isn't selling you chineese knock offs. They are common in this industry and they may not last ten minutes in your Tv. I suggest some place like ACME out of Florida
where you will be assured of getting Sanyo original Ic's and not some chineese look-a-like.
Also, make sure to test the 3.3 ohm return and low ohm feed resistors in the convergence circuit when you replace the amps. You may find one or more resistors in the return changed in value or open so I would suggest buying a package of those also (10 in a pack).

I have purchased 3 new lamps. one lasted 900 hrs.

Your lamp is rated for 3000 hours. Is the fan working to cool the lamp? When you turn off the projector do you allow the fan to continue to run? If not the lamp is not cooling evenly and the lamp will fail. Th filters should be cleaned regularly and the vents be unobstructed.

It tells me that the lamp is not working

The lamp is probably burned out. They go after several years. You would most likely need to purchase and install another lamp(s)

Toshiba 55 inch hdtv lamp

this is a crt type tv- no lamps just crt's if it was moved recently then a seal could have been damaged on the crt cuasing coolant to leak down the neck getting into the socket. this will cause trouble for sure also could have a crack in the crt. look for a sticky liquid in the bottom of the unit.
sometime the crt's can ark and rip out a video output chip on the crt socket check it out.
not common but not unheard of.cheers

Green light flashing & no picture on Toshiba 40pw13p

There is problem with the lamp. It might need to be replaced. The lamp unit is on the bottom-left side of your TV. Loosen thumb screw (by hand) to take the the lamp unit door. Using a screwdriver, loosen two screws of the lamp unit and carefully pull the lamp unit out.
Put a new lamp in reverse order.

Ive got toshiba 40PW13P rear projection tv and it has convergence problem where more then one colours apear on the picture.

Well, you didn't ask what you wanted but I think you should try 2 things. One; unplug TV's power cord for 5 minutes, reboot. Two go into the customers menu and try to adjust the convergence.

If these fail call a factory authorized service dealer. Good luck.

Toshiba TDP-S8U Projector doesnt work

Hi j cwff

I would have said to take out the lamp and check for any visible damage , but if there is no response at all , you will most definitely be in for a Mainboard replacement that is going to cost a bit more than you might have expected.

I have however found that some people give the diagnosis of a faulty Projector totally wrong and it might be that the lamp is just blown - in which case the machine will switch on , but the lamp LED will flicker without any light being projected - then you can just get a new lamp for it.

Once you receive the Projector and checked it out for yourself , send me a request with any additional queries you might have and I'll happily assist you.

Thanks for using Fixya and good luck !

Toshiba TP55F80 convergence problem?

check the convergence chips for bad solders or even the crt sockets, I would lean more on the ic's and surrounding area.
