On the main board of the tv there are capacitors and ICs .as you said you kept the tv off for two months ane now again connected and the tv did not start.as the high current passed through the circuit board of the tv and due to that any of the small electric part on the main board got blowned off and there is no power.check on the main board.it also happens if the moisture is collected on the main board of the tv in two months and when you started the tv now due to that moisture when the current passed in to the board and some thing got short on the mainboard.or due to dust particles collected on the main board.clean the main board.
thanks.

It is most likely a power supply problem, you can check the fuses if you like, but you would need to take the back off for that.

    If you are good with electronics, and have good soldering skills you could try to fix this yourself. I advise you to take it to a service center for repair. These are not easy things to fix without the proper equipment and training.

Check out the fuse on the main board if that is blowned this could happen.

    also check out the power supply wire of the tv which you connect to the electric outlet , if that becomes loose internally this could happen as no required current is given to the tv to power ON.

Mitsubishi WD-60735 Control issues


This set has aside from the recessed front reset two more done with the Mitsubishi remote.

The soft reset "should" be with set on Menu, 1,2,3, enter

The hard reset requires a 4 digit number code and is based on model number and also done with the Mitsubishi remote--try to see if soft reset works at all on this model.

When I turn on the tv all i get is the welcome screen, and it will not go any futher,there is green light flashing in front of the tv. and it will not turn off with the remote, i have to unplug it.


Hi Andre,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code to narrow down, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.
Regards,
Jdvillanueva

Mats Electronics has remotes for this TV 1-800-628-1118 $3.95 and up
Encompass Parts Distribution go to this website and type in your model number it will List Parts/ Prices available. In the mean time go to the Dollar store they will have a 4 in 1 RCA remote with code book for $6.00
I have used this remote on many different TVs it works almost all TVs.
The reset button should be on front of TV under a panel door .I also know that Mitisubishi has poor solder connections on IF and Tuner boards you may want to resolder theses boards.Your DirectTv book in the back should list TV codes for your TV to program their handunits to control your TV,if you cannot find your book then Call Them, they should be able to talk you throught in programing your TV to their hand unit.

Have you tried holding the input and menu buttons on the set both in together for 8 seconds to see if it will blink a 2 digit error code? Try that and let me know what code if any flashes from the Led.

The problem is in a circuit called "pincushion" Most likely you have capacitors failing in that circuitry.
