I was just given a Toshiba 50MH66 DLP rear projection TV from my FIL. It was giving him some issues with the screen but it was working when he replaced it with a 4K LED this past winter. I just started trying to use it; sound but no video. Did dome troubleshooting and ordered a generic lamp from Amazon. Swapped it out with no issues but I still have no video. It clicks , I have the blue power light and a blinking yellow bulb indicating a lamp issue. Not sure if fan or "color wheel" (?) is working.
