I have a Hitachi 57 " rear projection TV, the screen is dark


Unfortunately it sounds like your CRT's ( picture tubes ) are getting weak. You have 3- red, green and blue. It would not be in your best interest to repair it because of the cost of the crt's and if we can still buy them. A lot of analog parts such as those are very hard to locate and is getting worse by the day.
