Question about Toshiba 50H13 50" Rear Projection Television

1 Answer

Deteriorating picture quality at power up

Hello, My 50H13 is experiencing a progressively worsening condition. At power start-up, the screen is very unclear (static, distortion, etc..) and gradually gets better and then is completely normal after a few minutes. It started a few months back as just 'minor' distortion at the top of the screen at power on, but now the entire screen is affected. I have yet to take any corrective action and am asking for guidance. Thanks

It sounds like you need a hyper board for this. This part may not be available form Toshiba but I think I still have some in stock. You will likely have to have a technician insatll this for you.

Hello rqromero2,

I found this on HP's website. I hope it helps

Picture quality problems (such as lines, fuzzy image, or wrong colors)Check the cables and connections:
  1. Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors.
  2. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
    Press the CH button to display a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  3. Make sure that the image quality issue is not coming from your source signal.
    For example: if the image quality issues occur while viewing TV, switch the source to a DVD player to see if the image quality problems go away.
    If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and .
    If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
  4. Open OSD to adjust the picture:
    Press the Menu button to open the OSD. Select the Picture menu and adjust the image as needed. 
    If you cannot adjust the TV to fix the problem, reset the settings from the OSD to see if the problem goes away.
  5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV. If the image quality problems still exists across all types of signal sources, the TV should be serviced.

If this dosent solve your problem, letus know and we will find another solution,

unplug the set for a half hour and start over. As long as you did not save the settings, all should be ok.

you might wanna look into the "flicker issue" with your set...If you've had it for a while a could be that it's just worsened over time and developed into a voltage leak. I have the same set and it went undetected for a couple of years due to poor quality cable signal..once I went to a clear signal (ie. directv) the issue was very noticeable, but by that time it had progressed. Eventually one of your guns will fail and the set will stop working all together (mine did just under 4yrs from purchase) and unless you have Sears warranty that WILL try to stick it to you. TRUST ME!!! Good luck.
