Hi, The problem comes from what we would call a "contaminated circuit board". The board has to be replaced or repaired. Since the Television is less then a year old, I am sure the manufacturer has a 90-day parts and 1-year labor warranty policy. Contact the manufacturer would be the cheapest method of replacing the unit. Thanks, Mike H.

SOURCE: tv worked fine last night. tried to turn on today

ONLY 1 or 2 things can cause this problem----First thing to do is remove front speaker grill--it pulls out and secured with plastic pegs--behind it you will find an inspection plate---Notice the one or two pairs of wires coming from the front keyboard2.gif of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)

The idea here is to remove the front keyboard2.gif with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---these sets have a Receiver(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up.

If disconnecting the keyboard2.gif allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and or replace it.

If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---you can call them and get a quote for repairing the receiver.

I see two possiblites your flyback tranformer has failed and with it your horzital output transitor has shorted. most technicians can replace these. IS the spark in the front or back of tv. if it is in the front this is a tube. as a tech i would first identify what compnents are sparking. also this could be a capacitor shorting cause a burnt curcit board

Screen is fine when I first turn on TV, then goes black


Sounds like you dlp lamp is going out. That's a pretty old TV and if you are still running on the stock lamp this is exactly the type of thing that will happen. The lamp model for this particular tv is the ty-la1001. You can find that over here:

Samsung 1080p turns itself off


Probably a bad Inverter board. I have a Dell 32" LCD TV but it has a Samsung Panel inside, found a burnt transformer on the inverter board, Still trying to find a replacement.


My TV comes on for a second then goes black, power still shows on but no picture. 1.5 years old

If you are not a tech person, take it in for service.
