Same thing happened to me.On the signal board there is 4 surface mount transistors. There is oneright by the input board (BA09), i would check the corresponding capsand diodesmitsubishi ws-55513 HELP!!! - 2_bing.gif 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 thanit will go away in 3 min or so and get worse over time until no pictureis seen. When it totally fails you will have no inputs what soever butyou will have an OSD screen and when you choose DTV you will get ascrolling picture.

TV's picture and sound goes off. Had to cycle Mitsu WS-55513


THERE IS, aside from having the set taken to a shop, One other thing you can try---

NOT THE RESET BUTTON ON THE FRONT OF THE SET!

If the original Mitsubishi remote works on the set---this set has a hidden menu---it also in that menu has a HARD RESET---puts set back to the condition is was when new in the box--will come back on on channel 3 in the air band and any labels you placed on any of the video inputs (ie--named a input DVD etc) will be gone.

If you have OSD but no video either you have some problem with a single voltage coming out of the power supply(shop repair) or if you had a power outage or the power cord was removed with the set on---the hard reset may fix it---nothing to lose--set is not usable now---

Let me know if you want to try the reset and I will tell you how----

The other night while watching the tv turned off by itself.


There are two usual causes for this. One is the convergence integrated circuits have failed. The second cause is slight leakage of one or more picture tubes.

Shuts off after 15 minutes


Most likely you have picture tube coolant leakage on the power board. Have an authorized Mitsubishi service shop take a close look.

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
