Mitsubishi ws-48413 Screen just stays black when turned on. Green power lighpower light does come on but nothing happens. The green power light will shut off by itself after 3-4 minutes. Not sure of relevence but this is a vacation home and the tv may have been left on after a dvd was taken out five months ago.

You need a tech who can check on the system board as there is a capacitor which needs to be changed and after the power drain you need to reseat the cable of the device from the board to screen.

Hi and welcome to FixYa,

Initially, the presence of the green light is indicative that power is reaching the electronics inside, at least the power supply board. It also indicates that the standby +5VDC is present. When you press on the remote to turn ON completely the TV, would there be a clicking sound? Or some other indicator that the rest of the electronics inside are receiving power? If none, offhand it would be suspect of the power supply board is not supplying mains B+.

This of course would require opening the unit, perform voltage measurements,determine faulty component and subsequent part(s) replacement. Further, a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Good luck and Thank you for using FixYa.

TV will not turn On


Call a good TV Tech and have him check for vented capacitors in the DM module or blown pico fuses on the -24 and the +24 volt lines.If fuses are blown,it indicates the convergence amp IC's are bad.The fuses solder into the board.

Have a ws-42413 mitsubishi TV


This behavior could be an indicator of power supply problems or abnormal current drain from elsewhere in the set.
Modern supplies are, by design, able to shut down if voltage or currents aren't within the design limits of the circuits they are servicing.
Without some hands-on it is not possible to isolate the problem unless one of the forums deals with a series fault.
If the set had a reset button, it would be located on the outside of it where the user could reset it.
The reset buttons one finds on some sets is nothing other than a very cheap kind of thermal circuit breaker that trips when current is above its limit.
These are kind of prone to failure themselves.

TV WON'T TURN ON


You might have a bad power supply or convergence circuit, I also suggest you to check for fluid spill on the circuit board. if the convergence is defective one of the 5A picofues on the power supply is open. Hope this help you.
