Question about Mitsubishi WS-55807 TV

Mitsubishi WS55807 - sound / volume fluctuates

I have the TV since 2000 or 2001. It just happened yesterday that the TV's sound will become loud for a few seconds and then come down. The volume can not be controlled anymore. Out of 100 minutes of TV watching, the volume will come up and down for about 10 minutes of total time. Beside this problem, the TV will occasionally display some white lines cross the TV. The lines will stay for about 3 to 5 seconds. This only happened for about 1% of time.

This model is equipped with a keyboard lock feature. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds. If this doesn't help you have to make some checks in set. First IC7D04 (temperature related) may cause lines in pic. Check 9v DC on terminal PCB at Connector JA pins 57&58 if missing then change IC9C25 part#270p677030 on signal PCB.

What source(s)? Verify the speaker setup with the test tones to prove the hardware is all okay. Then go back and evaluate the conditions that create the problem. It could be an external cause.

I have a Vizio 47 inch LCD HDTV hooked to a Dish system. The volume fluctuates from very loud to very soft between ads and programs. It also goes from moderate volume to very soft within a program. Help!


Either unplug dish from tv or use the antenna side which is HD and program channels and see if volume the same, if not and is OK then it's your Dish bring your sound down or audio cables bad.

Concaved distorted picture in 1080 Mitsubishi 65" TV.


This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.

Got t7900`


Hi,

I have had that problem with a T7700/T7900 speaker system.

Disconnect the remote control from the subwoofer. Then what you need to do is unscrew the remote volume/bass control unit (4 little screws). Swab the contacts on the volume dial with a cotton bud (q tip) denaturated alcohol or even perfume will work. Make sure you do it several times until all the slight dirt that is causing the volume fluctuation/spikes to happen. Also remove any remnants of cotton that might get stuck.Now you'll have it working as new as long do not cause any other damage to the unit.

Cheers,
Daniel
