Mitsubishi vs-6043 Has faint black horizontal lines and a faint high pitch noise that fades in and out when the picture changes. Could there be some cold solder joints I can check?

The problem sounds to be in the horizonal oscillator. It could be cold solder joints, but it is no doubt a leaky caracitor in the oscillator circuit. Check caps close to heat sources like heat sinks, power transistors and power resistors.

Monoscope signal how to get it Mitsubishi VS-6043 rear tring to adjust the picture its all warped looking got tv out of ditch tring to make it work


does the convergence align or move? how is the picture distorted? if the picture aligns but is just warped, use a jig or some string to have some straight lines to reference for your geometry and convergence. the monoscope signal is hard to find and mits had it on a vhs tape back in the day. it really just helped you get the horizontal and vertical size and get a round circle to fix the warp.. just try to make all the grid points about the same distance apart and make it an even grid.

Not sure on that one. My local repair guru tells me the 6043's are constantly having problems. I've got one that I'm looking for board parts for, so if you end up not wanting to fix yours, I'd love to get your board set for some parts.

Mitsubishi VS-5071 rear projection turns on, has audio but no video


That is a VZ3 chassis, similar to Mitsubishi models Ts-4545, Ts-5045, Ts-5545, Vs-4543, Vs-4544, Vs-5043, Vs-5044, Vs-5047, Vs-6043, Vs-6047 and has common failures in the vertical circuit, specifically vert Ic401 which is a La7845 which is usually caused by defective C402 100uf 50v and/or open 1.2 ohm 2 watt R510 next to FBT.
If not that check C268 off Q215 on signal board 22mf/50v and Ic200 on signal module Cxa2025s. However the vertical failure is more likely.

No picture or sound


From the symptoms you describe, it seems the high voltage flyback autotransformer has failed along with the horizontal amplifier (they are slaved to each other). The sound comes from the flyback unit.

Well, the only way to solve this is to get a technician take a look at the set, I'm afraid. Repairs could cost upto $100 or more, depending upon the number of components that need to be replaced,

Hope that helps!

Black horizontal lines on mitsubishi VS-5043


Is the noise in all inputs (line, tumer) ? If it is in the tuner alone, check the coax lug to see if you knocked it loose. This could be the problem. Check you picture with a DVD player on the Video input. Let me know what you find.

Mitsubishi vs-6043 turns itself off.


On this set it could be 1 of 3 common problems. first it could be the regulator ic in the sets power supply. It could also have a shorted horzontal output transistor because of cold solder connections on the horizontal drive curcuit. and finally could be cold solder connections on the colis and or the high wattage resisters in the sweep power supply and horizontal output section. You should first put the set if you can on a variac transformer and lower the ac voltage to 85 to 90 volts ac and see if set comes on. If it dosent static check the voltages on the pwer supply when powered up if they are there then check the horizontal driver and output problems.. If you understand what im saying and have the proper tools good luck to ya but if you dont it would be best to take or have a pro come and check it for you.
