Question about Mitsubishi WS-55513 55" Rear Projection HDTV
I turned the set off the other day with the front on/off switch. This morning, I tried to power up the set and even after trying to use the system reset, un-plugging the set, and trying everything I could, the set would not power up. I unplugged the power and waited the customery five seconds, used both the remote and or power switch. When the system reset is pushed, the gree light in front blinks rapidely, but it goes out after that. I have had this happen before. I saw some possible solutions to this problem in other postings.
These sets have a common problem with the front panel buttons sticking and not allowing the set to turn on. Unplugging the control panel and using the remote to turn the set on normally diagnoses that problem (If you try this, remember that once the set is origionally plugged in, it takes about a minute and half before the set can be turned back on. Another problem could be in the convergence circuit. If you hit the power button and the indicator light comes on and shuts off then that is the circuit that is most suspect. The -24 volt line fusible link as well as the 24 volt line will open up if the convergence IC shorts out. There is a way to diagnose this set by pushing in and holding the menu and device button on the set at the same time until the indicator light starts flashing. There are two sets of flashes, such as, 2 flashes and then 3 flashes. Hope this helps.
