Re: Mitsubishi Vs-5003r

Change both 47uf 100v caps , both 47uf 50v caps and the 10uf 100v
cap in the primary side of both SMPS transformers. also replace R903 270K
that sometimes opens and the 1k resistor Damon spoke of ,then solder the
heck out of the board. Be careful not to crack any traces from the
components as the traces are very fragile and a mere bump of a component on
the front of the board can cause hours of troubleshooting.

WS-55517 Mitsubishi Rear HDTV projection tv will not turn on

2 blinks followed by 1 blink is the X-Ray protection-----means some problem in the High voltage circuit ---set produces over 25 thousand volts to fire the 3 picture tubes inside up----It could be excessive high voltage-------I think you would have to get lucky for someone to find and fix it in your home----more likely it will need a visit to a Repair shop.

Hi there

Try replacing the electrolytic capacitors in the power supply section. I started with replacing (2) 860uf 180v caps just after the bridge rectifier and continued along the circuit. Some (15) or so capacitors later, it fixed the intermediate problem of no video, when turning on the power.

Here is a picture of what they look like:

Mitsubishi VS-5041 (TV turns on but no pic or sound)

Your problem is one and or 2 differant problems. The power regulator could have went bad because of the convergence IC have shorted. Seen this a thousand(easy that!)Times. All parts in this set are soldered in and are not user serviceable. look in your owners manual or call 800-332-2119 to get an authorized servicer to come and look at your problem . I wish i could tell you what to replace but theres the Extreme Hi voltage inside these sets even when they are not plugged in .. Good Luck
