56HM195 Light Engine Troubleshooting

I have a barely used but out of warranty 56HM195. A minute or two after turning the set on, video on the left side of the screen begins to display a block pattern (it looks plaid, if you can imagine that). The dividing line is straight down the middle. After the TV cools down and I power it up again, the picture looks great for a minute or two, so I'm guessing it may be a thermal issue of some sort. It looks as if replacing the light engine is a simple process. However, before going to the expense of getting a new one, is there any troubleshooting to the module I can do? If not, do you know of any good rebuilders? Thanks.

You should make sure that the onscreen menus are effected by the problem if they look OK and just the video bihind them is distorted the problem is in the digital video or what Toshiba calls the seine module. Probably not though it sounds like an engine. PTS electronics rebuilds some engines however most Toshiba engines are relatively reasonable.

Hello. I have a RCA LED50B45RQ TV that has standby light illuminated when turned on with remote white flashes on left side of screen for a couple seconds with no audio or video.

Your RCA LED50B45RQ TV appears to have a problem with the display and audio.
When the TV is turned on and the remote is used, the standby light illuminates, and the screen flashes white on the left side without audio or video.
Various factors could be to blame for this problem.
A few troubleshooting tips are provided below:
  1. Check the connections: Make sure that all the connections between your TV, cable box, or streaming device are securely plugged in.
  2. Check the settings: Ensure that the TV is set to the correct input and that the cable box or streaming device is set to the correct output.
  3. Check the backlight: Some TVs have an adjustable backlight setting. Ensure the backlight setting is turned on and set enough.
  4. Check the cable: If the cable that connects the TV to the wall outlet is damaged, the TV won't turn on. Try unplugging the TV, waiting a few minutes, and plugging it back in.
  5. Check the power supply: The power supply could be malfunctioning. It could be damaged or not provide enough power to the TV.
  6. Check the Main Board: The main board controls all TV functions. It could be malfunctioning, which is causing the TV not to turn on or display correctly.
  7. Contact the manufacturer: If none of the above solutions work, it may be necessary to contact the manufacturer for further assistance. Your TV may require repair or replacement.

Your problem certainly sounds like the light engine, but is hard to say without looking at the set.

I have a toshiba 56Hm 195 only half has picture

a PROBLEM likely to be either in the optical light engine or a separate digital board in the set---engine is more likely and a very expensive part not to mention labor.

Green/Pink Screen

Is this on all inputs? Have you tried unplugging the set for 2 minutes then trying it again? Did you check all of the connection ong to the set such as component cables leading to a HD cable box? If so then the parts should still be under manufactures warranty.

Redish distorted cable picture until I change input source and then go back to cable input

When you say brand new, just how new is it? Your unit could be covered by the warranty. Certainly something worth checking into. If it works fine on all inputs except cable and the cable box has been changed your problem is probably in the digital receiver in the TV. This is something you will need a qualified repair tech to look at but should not be an expensive fix (compared to the cost of the unit). First make sure it is not covered under warranty. Free is still better than having to pay! Good luck.
