Vs 5043 mitsubishi no picture


Dear dc_rock,
These the most common failures for this TV Model VS-5043- VZ3:

1. Check base bias Voltage of Q217, for 0 VDC (BIASED OFF) if .7 VDC (BIASED ON) check C268 (22 UFD 50 V) off C OF Q215 V-Protector on the SIGNAL PCB.

2. Vertical Beam Blanking Active, check PIN 4 of IC401 for 3 VDC. If missing check IC202 (5V REG) PART # 266P932010, on The SIGNAL PCB.

3. Check Pin 6 of IC200 for 9 VDC if low or missing check IC203 Part#
270P210010 on the SIGNAL PCB.
Thanks for using FIXYA, big IRISH.

Mitsubishi vs-55707 or vs-50707????? bouncing horizontal lines weird color


If the picture looks like a 3D then you have a convergence failure.
I would suggest to visually inspect the STK Ics for dry or crystallized solder joints.
IC8C01 - STK392-110
IC8C02 - STK392-110

Mitsubishi vs 5043


I turned the set on and everything was fine, then the screen went black and mullti-colored horizontal (arched) lines were flashing across the screen. The next day I turned the set on and everything was fine for about 5 minutes then the problem reoccures again. Haven't looked for solutions till now.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.

Mitsubishi ws65909


Yes,but first it is necessary to repair the problem = replace
both STK392-570 IC's.............Then use remote to adjust
convergence............."inside the tv" is called servicer menu = adjust after repair is complete.You can expect to replace IC's
every five years or so.......................T.

PS Try to match your problem thread model # to actual model #
ie. VS-5043 does not match WS-65909........T.

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 model vs-5043


I just had this same exact problem. I looked for an answer on here and could not find one. So I took the back off, vacuumed and cleaned everything out with the hose on my house vacuum, cleaned the bulbs and wiggled them around some. Voila !!!! lights on and all is working fine and better then ever. I hope this helps someone fix their problem. Just saved me tons of money and a morning of hassle.
