Question about Mitsubishi Televison & Video
Is this something I can fix myself? [pretty mechanically inclined]. This just happened last night. I can let the TV sit for an hour or two to cool down and then I can turn it on and get a picture for about an hour or so until it heats up and shuts off again.
The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size

Testimonial: "Thank you for your response The Knight. However, this TV is an older rear-projection TV. I discovered this web article that addresses this problem and it sounds like the problem could be this: http://www.justanswer.com/tv-repair/7f15s-mitsubishi-ws-73411-doing.html "The suggestion I have for 23 error is to re-solder the plug connectors on the CRT yokes. Sometimes the solder joints of the pins on that small board get cracked and cause 23 error. On each CRT there is a 4-6 pin wiring harness with large gauge wire that plugs into a small circuit board mounted on the yoke. The boards may be under some plastic covers. You may not be able to see the cracks in the solder so I suggest you just re-solder every pin on all three CRT's. It's best NOT to remove the yokes and NOT to remove the CRTs because you will be in for hours of alignment. Do everything you can to re-solder the pins without moving the yokes. I have done it, you basically have to lay on your back and do it upside down. But it's better than hours of alignment." Your thoughts? Thank you for your time."
