Question about Mitsubishi WT-42315 42" TV

1 Answer

Lightning strike killed my wt-42315 mitsubishi

I press the power button and absolutely nothing happens. No click, no hum, just nothing. Could it be a fuse? Could it be the Power supply? I'm lost and I would like some advice before I call a technician to fix it.

    Thank you eagle338! I'll take a look inside my set. I will not touch a thing though! I just want to get an idea of what's wrong before I take it in.

    Again, Thank You.

Yes it can be either a Fuse or the power board itself. First lets talk about the fuse. What we are looking for is a burnt ceramic fuse
that will look like this http://www.radioshack.com/sm-ceramic-and-thermal-fuses--fi-2032300_cp-2032058.2032234.html
Check the rating( something like 5v, 2A or something like that) and get replacements with the same values. Should cost you around 10$ for 6 of them. If this doesn't help then its gotta be the powerboard and if this is the case then the powerboard is not user servicable. You will have to get it replaced! Good luck!

Regards,
Sai.

Which circuit board on my Smart TV might be broken after a possible lightning strike. There are two main ones. The power is getting to the unit, but I can't get the menus, connections etc to work.


Nobody can predict, what might have been happened to your TV after a lightning strike. Do you thing anybody can? Is any technician have a super-natural power to predict the faults that might have been happened due to lightning (More than 10 Million volts to start on stroke) ? Can you?
Sorry.
Contact the authorized service center. OK?

I have a mitsubishi wt-42315. when i turn it on it shuts down right away. any thoughts?


Do the self check this model has.

When you turn it on and green power light goes out:

on front of set press and hold both the menu and input (or device) buttons at the same time for at least 5 seconds and release both buttons.

The power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code you find and I will tell you what problem is.

If this helped rate this solution as very helpful as I do this here for free.

No power on


It could be coolant leaked from the CRTs, or a failed fuse due to the conv ICs shorting out or going open, depriving the turnon circuitry of its proper voltages.

These are the usuals. Since Mit has very elaborate protection circuits, it could be anything. More troubleshooting needs to happen before we'll know more.

I do a phone coaching service if you want to check that out.
