Question about Toshiba 46H84 46" Rear Projection HDTV-Ready Television

1 Answer

Toshiba 46HM84 DLP Black and white pattern..

I have a Toshiba 46HM84 DLP television. At first, I got a red flashing, solid green light that indicated I needed a new lamp/the lamp door wasn't seated. There was no sound and no picture. However, recently, when I powered it up, the TV actually turned on. However, there is a black and white pattern (about 1 inch tall, 3 inches wide) that spans the entire screen. Changing channels, inputs doesn't change the picture (but the screen does go black for a second to signify it is changing something). Any ideas? Thanks, Mike

While i don't recall that particular pro lemme alot of Toshiba sets had an issue with the ballast boars. Basically over time the solder connection s get hot and cool so much that the joints Crack and breal. The ballast board may need to be resoldered. If you choose to try this advised there are very high voltages inside a tv that can seriously hurt or kill you.

Toshiba 62 inch dlp tv keeps flashing green and will not turn on

green flashing for .3 sec with solid red indicates lamp problem. and do you have the manual? If so, look in the appendix for a section 'LED indications'. that gives you the code for the indications.
Good luck..

My Toshiba 62HM95 62 in. HDTV DLP TV won't turn on...the green and red lights under the power button remain on and the red light flashes. How do I fix this?

Most likely, you need to replace your DLP bulb. The one that comes with your TV will last a few years max. The replacements seem to only last about a year. D:

TV won't stay on

One of two things can be the the bulb is bad...two the ballast is bad. If the bulb is not bad then the ballast can usually be fixed by replacing a resistor on the board is labeled R3 and is a 1000 ohm resistor

No picture, siren type noise as restarting

My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?

No sound no picture and new bulb red and green flashing lights on power up.....

The problem is either the lamp ballast or the light engine. My guess is the ballast. Part cost ranges between about $75 to $150 depending where you get it. If you're handy you can replace it yourself. I posted the process elsewhere on this site for another Toshiba DLP question (I think it was for a 46HM84). Good Luck.
