"t", Yes I did checked those fuses and they are all perfectly fine. I have five jumper connectors in this model. I did push each pin one by one with a thin screw driver to make sure each pins are connected properly. |

t--
it was not a bad switch... if you recall, i could not control the tv power with either of the two remote controls, not just the sound.
anyway, I took off the cover as you suggested and disconnected the switch wires. There was no change. so I just started going through all the menu choices, and (i think) the a/v reset did the trick.
bottom line, i now have complete control of the system back and i don't need to leave my la-z-boy to turn on, off, sound up or down.
thanks for the assistance. |

I have a WS55711 and the main menu just scrolls thru the inputs and the remote does not work, tried to reset and power down and still the same. Thinking that the module for the remote is bad or ?

New user here, just registered after stumbling on this site via Google. I have a Mitsubishi WS-65413 and have recently run into a blinking bulb problem, but not the green LED. Basically my TV turns on, but all three bulbs (red, green and blue) all blink off an off randomly. Imagine a loose cable that is being jiggled, and that's basically what it looks like. This happens for all inputs, and all three bulbs/lamps blink out and back on together. Any ideas on what could be causing this? The most frustrating part about this is several months back this happened, but once I moved the TV around a little to check connections, it went away until yesterday. |

I'm still having the same problem. I have a Mitsubishi model WS-55809. I changed the IC's to a brand new Sanyo STK-392-570's cause I had a convergence problem. I checked all the pico fuses and they are fine. I checked the jumper connector and they are well connected. Now to test my TV. I turn it on and it turns off in a matter of a second. I tried it several times but it keeps on doing that. So I'd just leave the plug connected anticipating that it might reset somewhere. But it's still the same. So I unpluged it and try to checked the over all connection. But everything is plugged right and it's still the same. Does any one out there knows the problem? Please help. I know there are experts out there. Your help is deeply appreciated. |

Al,
I am having exactly the same problem. Started with the convergence with the red color separating from the image to give 3D effect. Later the TV would power down for no reason and when I kept pressing the Power button it would turn on. However since the last two days it will not power up at all. Press the power button on the panel or on remote the Power (Timer) LED light comes on for a second and turns off. No picture or sound.
I would really appreciate if you or somebody else on this group could help me. Repair cost estimate from a couple of TV repair companies ~$500.00 and no guarantees. |

"t" can't even start the TV at all. Is'nt it that before you could see the menu you need to turn on the TV? It just turns off when I turn it on. I turn it on and the timer light turns on a second then "click" it turns of. Do you think it has something to do with the timer? Does the timer has a resistor that maybe is burned out so it won't turn on? Thank "t". |

Al Dagsee,
2 - 2 = Short protect (short protect monitors low voltage supplies)
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 (NOT SHOWN IN THE SCHEMATIC). 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. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB |

Hello all, I know this might be rude but I have a question about a VS-4541. One day it just stopped working. I did some investigating and found that Q9A05 was desoldered, looked like an overheat issue. I resoldered it and it still does not turn on. I took out the boards and I hhave them on the bench but I really have no idea where to start. Can someone guide me?
My email is nalent@charter.net
Thanks a lot |

"t" thanks for the info. last night. I checked everything you said and found out that one of the Pico Fuse is dead, F9A05. It was good before but I think it was going dead and now it's totally dead}}. So I will replace F9A04 & F9A05 to be on the safe side. By the way does F9A04 means 4Amps or they are both 5Amps for both F9A04 & F9A05? I'm ordering this fuses on Monday at MCM Electronics. So they have a different Part Number.
Regarding the IC4B01, I realy don't know how to check it if it has a shortage. I'd tryed to use a voltmeter but it's moving. Does that mean that is dead too? Thanks so much "t". Hopefully this is the problem. |

I know this has been a hot topic on this board, but I have tried the fix and still no help. I have a WS-65813 tv bought in 2003, and like many others the little green light won't stop blinking. I have replaced the capacitors on the MD, but still blinking. There also seems to be a faint chirping noise accompanying this blinking, but it is very difficult to hear. Not sure if that is a sign that maybe something else is wrong with the tv. Anybody have an hints, tips, or clues that may help me out? I need it. |

"t" I'm still lost. Are we still talking about the IC4B01? This IC has 4 pins. If I'm looking at the board on the opening backside of the TV does number one pin starts on the back going up to the front of the TV? Could I check it with voltmeter? Could you please show it to me in an illustration if you can? Also what do you call this IC in case I order it? Thanks so much "t". |

Al Dagsee,
Just replace F9A05 fuse. I think you will be fine. It is a 5A fuse. You can put any kind fuse up there. Like, solder 2 pins on side of glass
fuse. Just make shure fuse not toches other components. |

when it happened the tv had sound but no video then i turned it off and back on and it had nothing. it has been a while since I had the main board installed. What I did find was Q9A05 had overheated like it was shorted, I resoldered it back into the board and turned it back on but nothing at all. I plan on replacing this transistor but I am not sure what else I should replace. TVs are not my usual electronic repair, I work with HV power supplies. Do you have a schematic for this TV? |

Thomas,
I think you have a bad connection on crt yoke.
It is easy to check. just look behind of connector look for bad solder. connection. Look for big connectors not converg. small one. look for vert. and horizon. They have a bigger connector with 4 wires on each yoke. |

are those the ones on the crt boards? the round sockets? if so I check them because I read somewhere on this post about that but I will check again. is there any other parts I should replace while I have the main board out? |

ok as far as i can see they are the connectors with th 6 wires in it, they are all good on all 3 yokes, I also just looked at the crt boards and they appear to be fine as well.also while I have the main board out I measured all the fuses and they are good. I am at a loss here. |
