Do you have sound at all? Wow where to start? If you have electronics experience - open the back and check the voltages on the power supply if they are good check the fuses/capactiors on the inverter boards- if you have sound and can see a very faint image i'd say the inverter boards are the issue - but without being able to get the menu, and change channels etc - i'd almost say that the av main board is bad - but make sure to check all connections - also you can google that board to see if it has any known issue.

thanks,
michael

Volume tv goes down its own


Depending on your TV, here are the generic steps Toshiba has outlined to reset your TV:

1. Press the MENU button on the remote (or MENU on the TV) to open the Setup menu.
2. Using the arrow keys on the remote (or volume / channel on the TV), highlight INSTALLATION at the top of the menu and press ENTER. A new set of INSTALLATION menu icons will appear.
3. Highlight the SYSTEM STATUS menu at the top.
4. Highlight SYSTEM INFORMATION below and press ENTER.
5. At the top of the SYSTEM INFORMATION window, use the arrow keys on the remote (or volume / channel on the TV) to scroll Left/Right through the menu bar to select FACTORY DEFAULTS. Press ENTER.
6. Highlight YES and press ENTER. To cancel the reset process, select NO and press ENTER.

Turn on the TV, red light stays on, picture goes blank after a second.


I have the same problem. Factory reset did not help (hold Vol-minus on set and menu on remote five seconds, then unplug). Can there be something in service mode that would help?

Go to your menu and choose picture. See if your settings are normal or if the brightness is turned down. If it isn't then it's a problem with the T.V.

I,ve got a red spot in the screen i replaced the bulp but stil have the problem


it is most likely a burned polarizing filter. There is a polarizing filter on the blue light channel and another on the red channel. When black, or other dark colours are displayed, the red polarizing filter is supposed to block ALL of the red light being projecter. If the filter is burned, some light slips through and creates a red tinge on the projected image. If the red tinge only appears on dark images, but is absent when the images is completely white, a damaged filter is likely the problem.

Seems its hard to buy them. Best bet is probably buying a broken projector from ebay and stealing the filters out of it.

Red Hue


Go into the service menu and turn down the red push and red cut a few notches. Write down every value in the service menu and be careful to make sure you don't change anything else. Also, turn down the brightness a couple of clicks and the red glow will be gone.

Or, try this - Press Mute on the remote control twice, press Mute a third time and keep holding at the same time, press the Menu button on the TV front panel. If you do it correctly, you will see a small S on the screen. Congrats, you are in service mode. Press Menu on the remote to get to the adjustable settings. Be careful not to change anything without writting the original value down first. Also be careful of hitting other buttons on the remote. To reduce red push, Use the channel up down button until it says RCUT. Adjust the value using the volume button on the remote. I recommend setting RCUT to 80H, which is the preset value according to the service manual. To exit Service Mode, simply power off the TV. Good luck.

Screen dark,wont stay on. 52hm95


Here's the online manual for your TV:

http://www.tacp.toshiba.com/tacpassets-images/models/42HM95/docs/42HM95_om_e.pdf

Read the section about the red/green lights in front. It sounds like the lamp went out. Mine consistently goes out once every year to year and a half. If you plan on keeping the television, purchase two bulbs, so you have one on hand in case your new one goes out.

Good luck.
