Try replacing I901 regulator ic. or contact a repair center. be very carefull as the set could still shock you after it has been unplugged. Some of these sets dont discharge the caps in the power supply.

    Look at and solder all solder cracks you can see. specially T703 next to the Flyback or HVT.

** TV won't turn on.** No picture or sound. Please Help !


If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

WD-65734 Mitsubishi TV won't turn on. System reset


Are there any lights lit on the front of the TV? Have you checked for a bad lamp? When you reset the TV the timer/power light should flash on and off rapidly for 60-70 sseconds. Does that happen?

Won' turn on


Please clarify,

Is the TV in standby and cannot turn on?

Or does the TV not turn on at all?

Check that it is turned on at the plug and plugged in. (sorry to be so basic)

You trying with a remote? check its set to TV not DVD if it has that setting / or the batteries are ok.

My tv. proscan mod. ps50700 won`t turn on


The PS50700 uses the 195 series chassis. The most common cause of the set not starting up is a shorted flyback (high voltage) transformer. Sometimes a shorted flyback will also cause the horizontal output transistor to short too. These parts need to be tested and/or replaced by a tech familiar with the RCA 195 chassis.
