Re: WD 52525 52" 2 1/2 yrs Problem with EPROM
I have 5 of these in my shop, green light continues to blink. Contacted tech support, they faxed me a list of things to try, including replacement of 3 boards. Replaced them all, same problem. I believe these are a problem chassis w/ Mitsubishi, along with WD 52527. Hopefully I will come onto the real problem.

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.
Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The
table in Figure 4-3 list the User Initialization procedures.
Note: Pressing INPUT and FORMAT is the same as
the Initialization in the Option Menu (MENU-2-4-7-0)

We have a 55in mitsubishi rear projection tv.
It was working great when the electricity went out (it was plug'd into a power strip) when the electricity came back on it did not turn on at all. The only thing that is showing that there is even any power going to it is a flashing green light by the reset button that does not turn off unless unplugged. I have followed the troubleshooting instructions for resetting etc but no help. Any suggestions would be appreciated. M Deisley
The number of flashes indicate an error code,you should call the customer help line that is in your owners manual and relay the number of flashes to the operator and they will assist you in a solution.
This is a very serious problem. The green blinking LED means the TV is reading its software but it can't complete the task. The cause is the premature failure of dozens of capacitors on several circuit boards in the TV. To properly fix this, the chassis needs to sent to Mitsubishi for rebuilding. You'll need to contact a Mitsubishi authorized service center to do this. This is expensive and takes quite a bit of time.
You can get the complete service manual for your set at the following link and they will provide free support to help you do the repair and even send you the instructions with pictures on how to do the DM repair. Your set Is the V23 chassis mitsubishi and thats how you have to select the manual. V23. Heres the link they email the manual to you instantly. http://servicemanuals.vstore.ca/
Try unplugging the unit and while unit is unplugged hold the volume up button and channel down buttons down and while depressing both buttons plug the unit in. Let go of the buttons and the unit should come on in the service mode. There will be a small k on the screen. With the sharp remote press the channel up button once. This should bring up a menu that will show a lamp error line. If the lamp error is = to 5 the unit is in lamp error shut down. User channel down to highlight that line and curser right arrow to highlight the lamp error #. Hit the enter button to clear the lamp errors. Now unplug the unit and let it sit for a minute and plug back in. I hope this corrects the problem. If the unit does not come on by doing this or if it does and you do not find lamp errors the power supply pcb may have been damaged by the surge.
