SOURCE: no pic...humming noice on 62'' toshiba dlp

was the lamp blown if it was blown you could be hearing the ballast
if the lamp was not blown and the new one did not fix it the red light indicates the door there is a little switch when you put the door back on if you look at it it may need to be adjusted so it will connect with the door if that is not it you could have a fan that is not turn if it is making a real loud constant humming noise while it trying to fire the lamp you probably have a bad color wheel

When the bulb on one of these Toshiba DLP units burns out, the unit will show a blinking green and a solid red, and restart itself 8 times, then show blinking green and red lights. A replacement bulb costs about $200 and is very easy to replace. If you replace the bulb and the symptoms continue, the problem is probably the ballast. The manual and Toshiba support will direct you to an authorized service center, but if you are ambitious and want to save the expense, here are instructions for replacing the ballast yourself. First, many thanks to those of you who have done this before me and posted elsewhere. There was a request for pics of the ballast board install, so here it is.


You will need:
1. A slightly long standard head Philips screwdriver.
2. A leatherman or small pair of pliers.
3. The Toshiba service manual. Refer to it often if you get lost. - download it here.
4. The ballast board (Toshiba Part Number: 23122468). I got mine from Conn's in Flordia here.
5. Some tape or a marker to label some of the cables so you don't forget what went where.
6. Patience. Lots of it. smile.gif

The Steps

1. UNPLUG THE TV! Put the TV somewhere so that you can easily get to the back of it. You'll need at least 3 ft of room behind the TV. REMOVE THE LAMP ASSEMBLY NOW.

2. Remove all of the screws on the lower part of the TV. Set the cover aside. It should look like this:


3. To get an idea of where we're going, as you look at the back of the TV, just behind the fan and lamp assembly is the ballast board, looks like this:


4. Next, remove the screws from the silver brace arm in the middle and the bronze screws that hold the light engine assembly. This brace is attached to the ribbon cable by a Zip tie; you do not have to cut the Zip tie if you don't want to. Refer to the service manual if the pic below doesn't show the screws clearly, but it will be obvious when you are looking at the "light engine sled".


5. Remove the bronze screw holding the plastic shield that angles down to the lamp. This screw is kind of hard to see just looking at the back of the TV, it is located up and above the ribbon cable attached to the back AV board.


6. Using a small pair of pliers, squeeze the plastic nipples in and push the cable hangers out of the plastic shield. Remove the shield carefully from the back of the TV and set aside.


7. Slowly and very carefully, remove the copper ribbon cable as shown. This copper ribbon cable was the hardest thing to put back in during reassembly, I kid you not. I hate that ribbon cable with all of my soul. Next, remove the yellow, blue, and red connectors as shown. If you forget where they went, the connectors are different lengths and only go to one and only one receptacle.


8. Slowly and carefully, pull out the light engine assembly. There are 2 yellow leads that power the lamp assembly that you can remove if needed. To remove them, slide the rubber footing off, and you will see a very small clip, push the clip back while pulling on the lead and it will come off. If you do take the leads off, be sure to label them with a marker or some tape. Mine were quite stubborn in letting go (I didn't see the clips under the rubber footing before this posted), so I left them on. If you do leave them on, be carefull of the stress on the cable going around the lens assembly. I removed the cables from the plastic do-hickey holding onto them and moved the yellow cables to the front of the lens assembly.


9. Next, slowly pull out the light engine sled and turn it so that you have access to the ballast assembly, like so:


10. Noticing how filthy your ballast board probably is smile.gif, remove the two screws holding the ballast board.


11. Now, remove the 2 connectors attached to the ballast board like so:


12. Next, gently push the plastic tabs holding down the ballast board to the light engine assembly and gently push up the ballast board to loosen it from the plastic tabs grip. There are two other tabs on the other side. Now you'll now be able to remove the ballast assembly entirely to install your new board.


13. Now, on the other side of the ballast assembly is the lamp connector. Remove the screws as shown.


14. Gently turn the lamp connector towards you to remove it; notice the orientation of the connector so you install it correctly when you put the new board in.


15. Now, install your new board and put everything back together in reverse order. This would also be a good time to take some compressed air and blow out all of the dust in there. Take your time during reassembly and be very, very, very carefull connecting everyting back together.

16. Be sure to put the back cover on, and re-install the lamp assembly before connecting your inputs and powering back on.

17. That's it! If you did everything carefully enough, you should be enjoying your Toshiba again and just saved about $350! Congrats!

Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck

You probably need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

Flashing Green Power on light not picture

Last Saturday evening, I experienced the exact same behavior on my Panasonic PT-52LCX65; it shut itself off without warning. I turned it back on, and it shut itself back off after about a minute, and the red "Lamp" LED on the TV began blinking.

I never got any warning message that the lamp was about to go out, but I've just replaced the lamp and now the TV is working just fine. We had to mail-order the new lamp, because neither H. H. Gregg (where I bought the TV on "Black Friday" 3 years ago), Fry's Electronics, nor Best Buy carries the part locally.

My wife found the new bulb WITH its holding apparatus for something like $120 online, roughly half what other sites were charging. We paid roughly $55 for UPS Next Day Air. The first bulb that was sent arrived broken (some UPS rep apparently thought "Fragile" meant "Shake and Drop"), but the company we ordered from cheerfully rushed us another one, and the second one was in much better shape. (Panasonic doesn't pack these replacement bulbs very well; there's a heavy bulb with a lot of air around it that Panasonic doesn't fill.)

More details available if anyone wants 'em. Hope this helps. -- ChuckE

Toshiba 65hx81 65" Rear Projection tv. black & white color/green

Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck
