Mitsubishi VS50603 will not turn on

I have a Mitsubishi VS-50603 that will not turn on. When I press the power button, the green LED next to it blinks quickly but set will not turn on, it apears to be some type of short. I attempted to reset it by un plugging the set for a couple of hours with no luck.

Mitsubishi Projection TV Model #VS-50603 will not turn on.

The TV is going into a "protect mode", the micro-processor has sensed a circuitry problem and has shut the set down so that no furhter damage can happen, you will need to have the TV serviced by a Mitsubishi tech. Good luck !

Disassembling Mitsubishi VS50603

Yes, it is possible!
Your set has three picture tubes, also known as CRT's, when the set is on there is aprox 30,000 volts going to the CRT's usually on large red wires that come from a common point. The CRT's can store a charge, the manufactures do put some circuits in that should drain that voltage away but if the set had a problem it may not happen.
Also, the CRT's are sealed in a vacume so if they are hit the wrong way can implode, all the glass gets sucked in toward the middle then flys outward. Another concern is inside the CRTs is a phospher coating, not good for you.

Mitsubishi VS-50603 Wont Turn on

The power supply will need to be changed. The capacitors inside the power supply are not sending the correct amount of power to tv and will need to be changed.

I have a Mitsubishi VS-50603 that will not turn on.

Good Day, jessayala;
It sounds like you may have Ethylene Glycol on the boards, leakage from the TV's CRT's. The Glycol is a fluid that help's the tube cool. If you are not handy, very, very handy, I would call an Authorized Service Center to come out and give you an estimate before the repair is performed.

Good Luck, big IRISH......PS..... If can handle your self ..... come back here.

Mitsubishi 50" Projection TV (Model VS-50603) Has sound but no picture

MJBNATL:

I reluctantly scheduled a technician to come out next week and take a look at my set. I was going to pay, at minimum, $65 for the service visit. I was then blessed with the intutition to do a bit more research regarding the PIP box being stuck on my television and other input functions (Inputs 1,2, and DVD) being unavailable.

I stumbled across a post on the internet that mentioned that the VS50603 can reset certain error conditions by pressing and holding the Input and Menu buttons (simulatneously) on the front panel on the TV while it is off. At some point after initiating this internal reset the LED light should starting flashing at defined intervals. The number of flashes correlate to a particular error code. Please go to the Mitsubishi website and download the owners manual (VS50609 in my case, couldn't locate VS50603) to lookup what the various error codes mean.

It seemed to me that that the LED flashing did not start immediately after pressing the Input and Menu buttons. In fact, I awoke the next morning to find the TV off but the LED flashing 10 times, pausing briefly, then flashing 10 times again. The sequence of the flashes mean something. Here again, consult your owner's guide for specifics.

Long story short, after awaking to find the LED flashing, I then turned the TV on and voila-my big screen was back minus that pesky PIP box prominently displayed.

I hope this helps someone like it helped me!! Truly a Blessing for sure.
