Projector power problem

My projector TDP T9 does not power on. Sometimes something flashes inside for 2-3 seconds and then it dark again. The bataries in remote are new, all cables connected correctly. The only light that is in on/off condition is the power light and it is green/yellow. The bulb  light  is off.
I would appreciate any help.

    I have a TDP-T9 doing the same thing. The power may come on for a second or two, the fan kicks in, the light briefly comes on and then it all goes off. I press the power button on it repeatedly. Sometimes it goes through it's 2 second thing, sometimes it doesn't do a thing. Sometimes it comes on and works fine for the whole movie. If anyone has had this problem fixed before, I'd love to hear the solution.

    I have the same problem with the toshiba tdp-t9 projector.Light tries to come on for a couple seconds than goes off and will not power up. sometimes nothing happens. This projector is fairly new with only a little over 100 hrs but just out of the 2 yr. warranty. I called Toshiba and told them other people have had the same problem but they offered no help.Is there an easy fix?

    I have the same issue. It was working fine until I moved it into a colder room and tried to turn it on. Nothing happens except every once in awhile the power like turns yellow for 1 sec then off. Not the best timing since we going to use it this evening for my son's birthday party...

    same problem. My projector only has about 50 hours on it. It statred flickering about a month ago and started to act up. Now it's just giving me the yellow/ green light.

    my TDP-T9 projector is fairly new and worked well for 2 months. Now it only light up for 2-3 seconds and turns off. Since the lamp light comes on, I taught the lamp was no good and so bought another. Guess what? it still does the same thing. I left it plugged in overnight and it's still no show. Trying to get someone on the phone, using the number in my manual is frustrating. Since I just got a new lamp, I would truly appreciate some ideas.

I had this same problem & almost threw it away!
If you have had it unplugged for a while just plug it in & make sure the yellow power light is on, then leave it plugged in for about an hour or two. Do not try to turn on before at least an hour, then it can easily be turned on. Make sure you reset the lamp timer option. There & you thought it would be difficult & expensive!

My T9U was doing the same thing. Luckily it was under warranty. They had to replace the power board according to the technician notes on my reciept. I don't know if this is a part you can get aftermarket or not. Interestingly enough, I am having the same problem again (it's been about 2 months) and I'm out of the manufacturer's warranty now. Good thing I bought that protection plan! I have one more year to get the bugs figured out.

Good luck with your projectors!

Sounds like your power wire to the keypad is either loose, or has a short in it. Its an easy fix for a pro, barring the motherboard is good.

I have connected my toshiba TDP-T9 to my laptop but I'm getting a "No Signal" error on screen. Could my VGA cord cause this?

Depending on your laptop, the internal splitter may be turned of. Usually the keystroke to turn it on is Fn F8. However it may be different on your laptop. Look at the function buttons, and the one with a screen looking thing on it is the one you press with your "Fn" key.

Toshiba TDP-P9 Lamp time reset

I had sleepless nights with my customers TDP-P9 projector where I changed the lamp.
The lamp timer resetting gave me headache but now I finally solved the right combo:
1: Unplug the power cord
2: Hold down 'On/standby' 'Input' and 'up arrow'
3: While keeping the buttons pressed, insert the power cord and wait for the projectors led's to flash briefly and then power button to keep illuminated and then starting to blink.
4: Release the buttons and power on, it should now have 0 hours in the timer.

Toshiba TDP-T9. the light won't change from yellow to green. we tried restarting the computer and the projector, but nothing seems to work.

Well first check the colour scheme of your monitor and of the projector.
If this doesn't work check the working hours of the lamp. Try cleaning the filters and if this doesn't solve your problem the best thing to do is to change the lamp of the device.
If you need further assistance please leave a comment. Cheers

The projector comes on, lights up but then shuts off after 30 seconds

My TDP-T9 had the same symptoms. A 3300uF 10V electrolytic cap in the power supply (Liteon) unit was domed up, so I replaced it with a high-spec 2200uF 16V cap costing three dollars. The re-flow solder on the board was damn hard to melt though, needed 400°C setting on the soldering iron.

Trouble with output to the projector

Hi there

Check the following on your laptop.

Right click on your desktop , go to properties and settings - check if your resolution of the PC is the same as that of your Projector. i.e. 800x600 or 1024x768

Also check that your secondary monitor is attached / activated.

If the signal stil won't pick up - hold down the Fn ( function button) left of your spacebar and press in your F-row of buttons the one with 2 screens on it. ( differs from brand and model )

Hope this helps you and good luck with your class tomorrow !

Reset Lamp Hours Timer

This works on a couple different Toshiba models -- might work on yours...

Make sure the main power switch is OFF. Hold the "ON", "MENU", and "INPUT" buttons at the same time and turn the main power switch on. Keep them held until the yellow power standby light comes on, then let go. It is done.
