Left tv unplugged for a few months no tv won't turn on
I have a 50" mitsubishi projection tv. I left for florida this winter and unplugged it. I returned after 5 months plugged it in and now it won't turn on. The red light on the front comes on the geos off, but tv never turns on.

Re: left tv unplugged for a few months no tv won't turn...
The first thing to do is try to turn on the set with the remote and then when it doesn't respond go to the set and hold down the MENU and INPUT buttons at the same time until the power LED starts blinking a two sequence code. Like 2 - 4 or 1 - 2. The code will keep blinking for five or six times and stop. The blinking is the microprocessor telling you why the set is not working. We techs call that a self diagnostic function. Which this set has. Just repost your findings.

This is called the blinking green light of death-----only one of two things can cause this problem.
First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.
Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)
Try (after 70 seconds) to turn on with remote
If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.
Second: if disconnection of the front keyboard does not help, the DM unit is bad.
As you look from back of set it is large metal box at extreme left side.
The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.
Let me know if you have questions and try disconnection of the front keyboard FIRST.
this is mostly in the eye of the one who thinks they need one!
12 months of age 60% its purchase price if it is in good working condition 24 months 50% 36 months 25-30% 48 months 10-15%
Beyond that it will be heritage listed and bring twice the price of its original outlay and be sought after by Mitsubishi who will be amazed that they actually made a TV that lasted that long. The average life of amy Mitsubishi and quite a few other modern Tv's is about 3 years before they require huge repair expenditure. Often better to update wvery 12 months if you can afford it as they are not built to last like the old CRT's that will still deliver on a set top box long after plasmas and rear projections have been retired.
Replacing the whole board will fix it, but is a bit of overkill. If you can solder and feel comfortable working inside the set, you can fix this yourself. Let me know if you wish to attempt the repair and I'll proviode additional details and instructions.
