Play with it. I usually just do 0 0 0 0 0. It is supposed to how many grids are displayed. |

Thanks again minnie I played around with the grids and it appears to be the best ts going to get. I made adjustments then saved them to the rom. Now my front panel convergence controls are working again. As well. And I made some adjustments there. I think its at the best going to be so I'll leave well enough alone picture is pretty good to me. I learned quite a bit thanks for the attention. I'm so impressed with myself as of late that a friend has a rear projection tv he wants me to look at, he states the TV has to be on for about 10 minutes before he gets a pic then the tv works fine from that point on. I will get the make and model and post perhaps you have a solution. |

hysterical Im watching the dog wisperer and just saw your message. The guy was complaining about female dogs...too funny. I'm satisfied with the pic at this point, I'm lucky the TV even works. Earlier today I replaced S901 relay and again everything is fine it was a snap.
I have a friend with a TV problem and he is describing it as follows: its an Akai model # PT5492S year manufactured 2002 what happens is he plugs in TV and the red light comes on indicating power but no picture/sound makes a buzzing/ticking noise. In order to get tv on has to plug and unplug tv several times until pic comes on but has to unplug TV in order to turn off TV off controls on both TV and remote not responding. If you want I can cut and paste this in a new thread. Thanks |

Thanks I kinda figured C was a cap. I will locate the Cap and I think you recommended B@D electronics if I recall correctly to order the part.
I really enjoy fixing this stuff and appreciate you help.
Thanks again Minnie. I'm not sure how to PM.. (and this guy is gonna put is hand inside a TV go figure...)lol |

Hey Minnie I would Pm you but I'm not sure how...I removed C835 on the Power/def board however it was next to IC801 I'm pretty sure this is not a problem...I hope. It is exactly as you said 22uf/25volt. It looks like such a simple electrolytic cap it looks ok I wonder if their is an easy way to check it? ...I am going to Rat Shack tomorrow to see if they carry this.One question, do caps have a + and - lead it appears this way according to the board layout. If so I'm looking at the cap as we speak and I am not sure which is positive and negative, any tips?? What a disaster taking this board out I am hopeful I can remember where everything goes.... |
