On RCA and others it just means that the AC power went out for a short time.
You may have to auto program the channels back in depending on how long power was out

Every time we turn on the TV, we get the message Did you replace the lamp press ok, if you didn't replace the lamp press cancel. Should I ignore this until the lamp burns out or replace it?


Make sure the AC power source is uninterrupted, plug into a wall to see if this fixes problem. Lamps should be replaced as soon as there is a problem - dim picture or intermittent operation of tv. Mitsubishi lamps last an average of 1-3 years. If you run a lamp longer than 3 years, older lamps start running hotter. When they run hotter, they will damage the optical engine, causing discoloration or the cooling fan to go out. The problem your tv has is that the power/digital module is in the process of going out. There are numerous capacitors that blow, and sometimes the digital board fails. You need to have an authorized shop pull the digital/power module and send to Mitsubishi for rebuild. We charge $225 labor and $300 for the part in our shop for this. It is a good (but expensive) fix!

I would suspect a faulty Zener or Diode, transistor, allowing dirty DC or AC ripple, to the Caps.. use a scope and have a look. One must always find the cause of why things fail simply fixing the symptoms simply means it will fault again.

Tv keeps shutting off with standby and lamp light blinking. what does this mean?


Good Day sir/maam, if your TV shuts off regularly, means that the power supply section is overloading, this may be due to faulty parts inside your TV, or either the AC mains in the community is to low or to high. If you want you can temporarily use a spare Auto voltage regulator with 500 watts, use it to levelize the AC main, if symptoms still persist, you may need to call for service. hope this helps. thanks

My panasonic rear projection tv will not power on and no lights turn on. Any suggestions?


Please plug TV in another power source and turn it ON,
if still does not turn ON, unplug AC wire of TV, take off back cover and follow AC cord f TV that will take you in power supply board, find fuse nearby and check is it blew off? if yes, replace it with same ratings written on it.
Plug TV in AC wall socket and turn ON, if fuse blow again that means power supply section in TV got problem and need qualified tech to find out and replace components or power board.
Thanks.

Tv turns on then off


hold the menu and input buttons simultaneously for 5 seconds. the tv will blink an error code
Error Code Probable Cause
12 Normal Operation - No Error Detected
21 X-Ray Protect
22 Short Protect - likely convergence IC failure
23 Loss of Horizontal Deflection
24 Loss of Vertical Deflection

Fast Blink for 70 sec. After AC is applied = Normal - DM μPC is booting up
Fast Blink (doesn't stop) After AC is applied = TV μPC is running, but DM failed to boot up
Slow Blink Set is Off = Normal - Timer is set for Automatic Turn ON

Here is the link to the manual if you need it; http://www.hdtvsolutions.com/pdf/MIT_WD-52525_WD-62525_WD-52725_WD-62725_Manual.pdf page 97 states that the lamp is the problem -(the flashing green just means startup - page 11) 14 months sounds about right for a new lamp if you use it a lot - that would be an average of 5&1/2 hours a day if the lamp went to 4000 hrs - although these lamps are more dependable than normal lamps, they can still fail anytime especially if they have been touched on the glass by accident while installing or cleaning, or if the tv is often switched on and off. The fact that there was no message on screen may mean that the lamp has not gone past the warning trigger number of hours - sorry i haven't found what that value is. page 95&96 gives all instructions how to replace lamps and where to get spares - if the price seems bad then search around - prices often vary a lot on these lamps. It is a little disappointing that mitsubishi where not able to diagnose this - please let them know that their technical service is poor in the hope that they try harder. I hope this helps :) Hope this helps :)
