Question about Toshiba TheaterWide 52HM84 52" Rear Projection HDTV-Ready Television

1 Answer

Screen remaining black after the TV is turned on

We have a 52" Toshiba projection TV, model 52HM84. Lately it's been acting up - the screen not lighting up. We get sound, but the screen remains black. The LED lights signal is solid red and blinking green - which they describe as possible lamp problems/door to the lamp unit not closed, etc. We checked the lamp, even changed it and still nothing. Then, all of a sudden it will work again. And then stop. Have you encoutered this problem before?Your help would really be appreciated. We called around, but since it's so close to Christmas nobody can come and take a look until next week.thank you,D Resendes

    same thing. shows green/red blinking light 3 times. High heat issue. unsure what to do either..............

    I have the same exact problem. Based on my research it seems that it is one of these 3 things.......Ballast, light engine or color wheel. The screen doesn't stay black though. When I restart, the screen goes on again for a few minutes-seconds. Really frustrating.

Some newer sets appear that way when there is NO signal to the set. That and my Sony looks like that when the bulb is burned out.

SCREEN FOR TOSHIBA PROJECTION TV


It may not be available due to the age of the set; If Toshiba does not have it there are some sellers on the internet: I would Google the model number with "screen" etc and see if still available or notTP55G60 was a well made model with a good picture and very few issues---you will not get this length of life out of the Plasma or LCD sets being sold now.

My 52" Toshiba DLP just dropped an HDMI connection... There are two connectors on the back, both have worked fine until just now when one disappeared from the inputs menu on the screen.


Hi,
I'm not sure about your tv model as question post shows it is Toshiba 52HM84 that has one HDMI input at rear and you said 3 HDMI inputs in your tv.
Please unplug tv from wall socket for minute or so to get it reset, replug back in, turn it On and check its HDMI inputs appear or not.
Also check for Reset option in Menu for factory default settings that can also help you to get back disappeared HDMI inputs.
If all that does not solve the issue then it seems hardware problem with HDMI circuit board and tv repairman is needed for visual check to get it fix.
Hope these info will help you.
Thanks.

The screen jumps around a bunch when i go to play games or dvds. sometimes while other things are playing also. not sure if its the resolution settings or what.


Sounds like either the PS3 is set to 1080p (52hm84 only does 1080i/720p) or you're ps3 is beginning to go. Try it on another HD screen or change to another input (HDMI --> component (RGB))
