Question about Toshiba 42H83 42" Rear Projection HDTV-Ready Television

1 Answer

Unstable video Two months ago the TVs picture would have slight wavy lines just at the top section when powered on. After about a 15 second warm up they would go away. Now the TV picture is totally unviewable for about the first 90 seconds. I have access to Toshiba parts but I'm not sure what part I need.

As with all products that contain a digital display, in rare instances, when viewing certain content (e.g.. television broadcasts, video games, DVD), you may notice that the sound and picture are slightly out of sync. This phenomenon can be caused by various factors including, without limitation, video processing within the TV, video processing in an attached gaming system, and video processing/different compression rates used by broadcasters in their programming. You may want to try one or more of the following suggestions, which may help to reduce the effect of this phenomenon:
  • If the TV is connected to an external A/V device (e.g., DVD player, video game system, set-top-box, etc.) always try to use the Color Stream video jacks and corresponding audio jacks or the HDMI input (if available on your TV) for connection to such external A/V device.

  • If the TV is connected to an A/V receiver that has a programmable audio delay feature, use this feature to help synchronize the sound to the picture.

  • If connected to a video game system and your TV has the Game Mode feature (see owner's manual for more information), enable this feature.

  • If you notice this phenomenon only on certain TV channels, please contact your local broadcast, cable, or satellite provider to inform them of this issue.

About two months ago when we first turned on the TV there were wavy lines across the whole picture. When it warmed up they would go away. Now, the lines are there almost all the time and it's getting...

You are experiencing a lack of vertical deflection or vertical collapse. Since it will come back the first thing I would suspect is “ring cracks” in the solder joint in the vertical circuit, mainly the vertical IC. These suspect solder joint can be re-soldered and the television set repaired.
I would suggest that you contact a local servicer. If you are repairing the set yourself, be careful, there is always a risk of shock when dealing with electronics.
Check your equipment connections. Disconnect your equipment (VCR, DVD or set-top box) from the TV and reconnect, making sure each connection is in tight.

Video distortion

You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

Picture Jumps/flashes for first 5 minutes

There is a module called a hyper board that is vertically mounted near the jack panel. Inside the module are 10mf/25v capacitors they are grtting weak. The module is fully shielded and pluggs into a socket. the module has 4 tabs (2 on each end) that must be unsoldered before it can be unplugged. This repair should be done by a qualified technician. The caps are surface mounts and very small. Unless you have excellent soldering skills and a rock steady hand DO NOT ATTEMPT to repair this problem on your own.

Very wavy picture- gets worse when show has fast-cuts

First thing Do not beleive peeps about a bad card. Modules are not used in TV sets any more unles your talking about a complete board change out for a Zenith TV set. Toshiba sets do not have a card or board changeout!.. These peeps are crooks! A Toshiba set is repaired to componet level. It sounds like you may have a convergence problem or a problem inj the power supply involving the filter or couping capacitors. Seek out a pro whos an authorized servicer for Toshiba.
