Hello Larry, I have a Mitsubishi WS 65869 that used to have the blinking green light. When I changed the DM board capacitors my symtoms changed. Now after pluging in the power the timmer will flash 70 sec then stop. When I power up the set the relay justs cycles constant ,clicks on and off on and off...all while you can hear the whineand HV static in the Flyback.
All the Standby and Switch powers are normal.
I went ahead and changed the HV out and Horizontal out Transistors along with the convergence IC. and tested surounding components.
when I powered it up it was doing the same thing. I then started to to make a video if my TV symtoms to show you when the set stayed on and worked.
But after 10 minutes of running the TV died and now when you power it up it quickly shuts down with no restart .No stored codes.When first pluged in the timmer still flashes and goes out after 70 seconds.Hit the power button powers up and dies.
MY MISTAKE !!!.....I was so glade the TV was working that I had forgot to install the convergence IC heat sink.Mabey this is why my set died afet 10 minutes or not.
I also found fuses F9A05 and F9A04 5 amp, open. They protect the -24 and +24 volt switched power. They were not open before when the set would not project, but after running 10 min they open.
I re installed the old convergence IC but the set still shuts off. Im going to order another IC but untill then, Larry do you have any ideas.
SHUTDOWN AT POWER WITH SELF DIAGNOSIS ERROR 2 2. CHECK FOR OPEN FUSES F9A04 AND F9A05 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT.
heard a pop and lost the picture. After inspection of the bulb, I found that the glass bulb was cracked and burnt out. I replaced the bulb. Now when I power up the set I have audio but still no picture. I then replaced the ballast. When I power up I have audio but still no picture.The set will cycle off then on..off then on and so on. I can hear a winding up spinning sound each time it powers up(the color wheel sound)..I was told that the power supply mabey has bad caps.
Im looking for the service manual for this set Toshiba 56HM66 so I can further trouble shoot the power supply circuit.
Thanks in advance.
