Question about Televison & Video

2 Answers

I have a Toshiba TDP-T9 projector. Had problems staying on, now doesn't come on at all. Checked the power wire it's good...interestingly, it gave me problems a long time ago, like the cord had to be in a certain way for it to come on. Anyways, I read the power capacitors go bad on this model, many others having the same problem with the TDP-T9. Where do i get this part/parts and how do I change it? I'm still trying to figure out how to get into this thing...I know that sounds stupid, but I am.

    It was coming on and shutting off after about 15 minutes, now absolutely nothing. No yellow light on. A month or so ago it would try to start the bulb then quit so I thought it was a bulb issue. I took the bulb out yesterday, it looks OK. Maybe 2 problems? First, I need it to come on, "get" power. I don't know where to buy parts or how to fix...but with some advice I'll try!

    Thanks, Sai. However, I have a Toshiba TDP-T9 projector, not a Hitachi. Maybe a simple mistake/wrong file? Thanks, again.

The problem you have is most likely to be on the ballast board(lap power supply). Since the cord used to work only in a certain position to work it may be a bad solder joint too. Fortunately I have uploaded the service manual from the link below. As for the capacitors, you can get them at any electronics store, but the new capacitors should be off exactly same specs as the old ones. For example : 120V 1000mf
Replacing them is by means of soldering de solder the old ones and solder the new ones in

Let me know if you have any more questions,

The capacitors do commonly go bad as well as the high-voltage transformer aka power supply.

    If there is no power to the unit, remove rear panel, look for a glass bus fuse. Long glass tube with a thin wire inside. If the wire inside is broken, then fuse is bad. Not all models have them.
    The high-voltage transformer aka power supply is the box that the plug-in is attached to. This provides power to the entire tv and commonly go bad in newer electronics. You can find the wires leading from the transformer to the main circuit board. You can test it with a multi-meter (ohm and volt meter) See if there is a reading. Then look on the supply or on the inside of the back panel of the tv. There should be a DC voltage output reading on it. Make sure the reading matches the label. Voltage should be the same. I have a feeling yours will not. If it turns out faulty. You will need to buy a difuser that will drain all remaining power from the power supply/transformer, then you will need to disconnect all the wiring to the transformer, then solder the old one off. Then you can go to partstore.com or shopjimmy.com or other sites and purchase a new one and solder it in.

    If you want to test the ballast with voltmeter, you can do that as well. The ballast is what powers up the light bulb. Placing black test probe to the ground side, and red positive probe to the inside where bulb attaches to and see if you get a reading. But if you tv is not powering up at all, then you will have to reading because power wouldn't be getting to the ballast if the transformer was bad. All you would get is the little lights in front to light up but that is all.

Toshiba TDP-P9 Lamp time reset


Hi,
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.

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-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 !

Projector power problem


I HAVE THE EASY FIX!
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!
