I have a Mitsubishi vs-50501 projection tv and when i turn it on, one of the anodes or something in the back is fried and sending charges which are sparking out of this piece on the motherboard. Didn;t know if I could cut of that circuit and solder on a new one.

Hello. in VS models there is no such a thing as a lamp. Your TV have 3 CRT tubes (picture tubes) each of them dedicated to Green, Red and Blue part of image accordingly. It is not the part that you can easy replace by yourself and it cost new around $600 and just to refurbish existing one around $320. But you have to refurbish all three of them at the same time. So we are talking about $1000 just for parts, not to mention enormous effort to align everything back together. If you have bad CRT in your TV - I would advise just to trash it and invest in new one. Lamp is replaceable in DLP projection Mitsubishi TV and it is next generation of TV"s. Model number starts with: "WD". If you still insist on part number - I need to know what color of CRT you need - they have different part numbers. Best regards Russ.
Hi name is Ernie, and i have a mitsubishi vs-50501a .... my problem is that the picture is out.. i got sound but no picture.. the problem started with the tv turning off after 15min. then i would turn it back on, 15min later it turned off again. So now it stays on but no picture.. let me know if i can fix it myself.. im mechanically incline.. thanks.
Odds are real good that the solder connections on the deflection yokes are bad. Go through the front access panel and with a small mirror look and the back side of the connector on each yoke. The top two pins of each will probably show 'ringed' solder connections.
Are there any other symptoms like blinking lights on the front or just no picture? This could be as simple as a few capacitors being bad or something more severe. Can you solder? Do you feel comfortable working inside the set where there are potentially dangerous high voltages present even with the set unplugged? Let me know and we'll work through the diagnostic process and hopfully resolve this.
Is the power light staying on? If so press imput and menu together for 5 seconds to see if the set will blink a 2 digit repeating code. If that doesnt work. Check for CRT coolant leaks on the boards. This seems to happen alot as do faulty capacitors. Coolant leaks will be located on the chassis directly under the tubes they can cause corrosion and prevent your set from starting especially in the VS models.
I have a similar problem. I have tried to fix the convergence via the remote and that has not helped. My three colors are separated and the edge of the picture is bent in toward the center. I am going to try a hard reset but i suspect the convergence IC are fried. Since the set is not HD, I will probably replace it if the hard reset does not work.
