Rear projector tv problems7/24/2023 ![]() ![]() Once you find this, disconnect all cables and remove the bored. This will require you to take the television apart and find where the convergence board is. If this doesn't work, then try replacing the STK IC's that are inside of the TV. Hopefully this has enough interest, because if it turns out to be as good or close to the vikuiti one could potentiall build upto a 10+ wide rear projection tv. First, go to the menu on your television and see if you can fix the convergence through this. The more contributors the less cost between everyone. Maybe there is someone here willing to shell out $100+ though himself to get the project running. I am willing to pay at least 20-25% of the cost myself if I have to. I don't think anyone wants to shell out $100 to try something that might work, so if anyone thinks this is a good idea and is interested in contributing let me know. If anyone else is interested in this project and wants to contribute to help get this project off the ground asap sign up here and the cost of the materials can be split between everyone interested and the results (with pictures/screenshots) will be posted here. My goal is to make a 10.5' x 5.9' rear projection tv with my commercial home theater projector A single layer would probably create the brightest picture though. I want to combine it with a matte/frosted clear paint and possibly transparent black dye and would like to try in layers too. There is a clear paint with microsphere beads in it. I think I may have possibly found away to make a DIY versioin of the Vikuiti black rear projection screen, but it will cost at least $115 just to try out with experimenting. ![]() The screen trumps every material I've tried it's incredible. The screen is basically a black absorbing layer on the back of a matte acrylic sheet with a thin diffusion layer on the back with millions of microspheres (glass beads) that redirect the light creating a bright, high contrast image with a wide viewing angle. Too bad that a 95" version costs about $5,000 and even a 60" version costs more than a 65" HDTV. I have a rigid rear screen sample with the film on it. That 3M film is most likely the one used in Vikuiti's black rear projection screen. I basically just need a few percentage more to project the images up against each other on the big RP panel seamlessly. ![]() I suspect that I need a lense in between to like "focus", is this correct?Īs I don't want to project each panel much bigger than they already are, I hope that it can be achieved with a very short focal length. However if I keep sheet at a distance, the image becomes more blurry the farther away I pull the image. If I backlit it and keep it just up against the panel, the image becomes sharp and looks fine. However due to the lack of knowledge within this technique, I don't really know how to project a sharp image onto it. I tried testing with a simple transparent sheet with a color image. I've already acquired some plexi glass samples, off one is a small piece of RP dark plexi glass. I'm planning to use Rear Projection in a short distance, hence the post in this topic. However, to get rid of the borders from each panel. Then, connect the monitor to another computer to check if it works properly.I'm planning to create a screen made of 4-6 smaller panels and software to combine it into one big image. Ensure the speaker volume of the monitor is not turned down or muted.Try different ports if your computer has multiple HDMI output ports to check if the port works fine.Check if it is the problem with the cable by using another cable.Thus, check if all the hardware devices can work properly before moving on to other methods. If there are broken hardware devices, sound not coming through HDMI occurs. Fixes for HDMI Audio Not Working Check Your Hardware Devices Next, you should take measures to get rid of the issue and we will show you some solutions to HDMI no sound. The problem could be the HDMI cable, your PC, your monitor, or TV there is an incompatible or wrong driver or even you choose the wrong playback device, etc. Sony will not even offer a pro-rata on the price of a new bulb.

The reasons for HDMI sound not working are various. 1 I own a Sony KF-WE42 rear prolection TV I am sad to say. However, many users reported that their HDMI connection can show the video but no sound exists. HDMI, short for High-Definition Multimedia Interface, is a dedicated audio or video interface to transmit compressed or uncompressed digital audio data or uncompressed video data from HDMI-compliant devices like a display controller to a compatible computer monitor, digital TV, video projector, etc. Just try them to easily get rid of the error.
