Mitsubishi 55" Projection TV / Horizontal Wavy Lines at Start Up

Noticing Horizontal Wavy Lines at Start Up on Mitsubishi WS-55513 projection TV. They last about 1 minute and then go away, upon start-up. Is this something a novice can repair and how much does it cost?

This is very common with these sets. the fix is to replace 11 very very smal capacitor on what is known as the hypermodule. The ideal sitation is to replace the hypermodule. if you can find it. I can do this repair. I have done about 10 at the shop. if you need to i would suggest finding someone who is very experence in surface mounted repair

We got our mitsubishi in 2000. it was working fine and then little by little the picture has wavy lines and you can't see the movie, it has gotten much worse. what can we do?


The wavy lines are caused by the aging of the vertical deflection unit = the defective parts (some capacitors and resistors) must be replaced.
The fix wont be very expensive - the parts will cost less than $25 - but you need a good electronics repair guy to do the job and this is going to cost you.
Remember, it's an old tv that has started to show its age. Maybe it's time to start saving for a new one.

Have wavy lines in picture sometimes-could this be a faulty wire?


On the signal board there is 4 surface mount transistors. There is one right by the input board (BA09), i would check the corresponding caps and diodes close to it also. I would replace all of the 4 transistors. If this SMT starts to go you will see wavy lines in your picture than it will go away in 3 min or so and get worse over time until no picture is seen. When it totally fails you will have no inputs what soever but you will have an OSD screen and when you choose DTV you will get a scrolling picture.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR LEAKY C9A60 470 PF 1000 V PART # 154P400030, PARALLEL TO D9A57 ON THE POWER PCB. 2. SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT
