04-10-2010 | 75 ohm connector repair | The 75 ohm cable connector broke off the back of the television. Can I fix this myself? If I take the tv apart is there a part I can replace? |
04-10-2010 | | Easiest way for the do-it-yourselfer with mediocre soldering skills to do this repair is to replace the tuner. Most sets will have a replaceable tuner, although there are a few, GE/RCA comes to mind, where the tuner is part of the main board.
Some sets h |

04-10-2010 | | Your problem is still related to the backlight section. Start by checking the power supply to the Inverter. I haven't worked on that brand but it'll be something like 24 volts. You can then also check to see if the "on" line is being sent to |
04-10-2010 | | It sound like your problem is related to the type of fuse you used as a replacement.
All power supplies will spike the current when they first turn on until the filter caps charge up. Cycling off and then on quickly will result in a lower spike current |
04-10-2010 | | its been a while but i finally sat down and checked this transistor , it reads likethe link says it should with mega ohms on s and g also g and d , the diode measurement shows good one way and open just like in the link , so the question is now what ? |
04-10-2010 | | Molte queste serie falliscono quando i condensatori surriscaldano. Guardare sull'asse di alimentatore per i condensatori che ha le cime che gonfiano. Provare a cambiare qualsiasi che lei trova. |

05-10-2010 | | [quote:bbdae75754="minnie"]Can you move all 3 colors horizontally and vertically? Touch focus has to be initiated in the service menu mode also. :D[/quote:bbdae75754]
Originally this is where I did the touch focus. I adjusted all the colours manually |
05-10-2010 | | I checked my board and the parts are exactly as described. Visually it is clear that the cap is bad, and my meter shows no contunity on the protector. Unfortunately, Encompass no longer seems to have the cap available. Can someone help me with a second |
