Re: auto convergence not working 142cm LG rptv

If the colors will not line up in one corner of a standard projection set, it usually means that one of the convergence output IC's has burned out and needs to be replaced. This is very common. If you do not have experience replacing parts and soldering PC boards, then the defective IC should be replaced and the convergence circuits realigned by a qualified tech familiar with convergence circuits in projection sets.

Re: auto convergence not working 142cm LG rptv

I have replaced the convergence I/Cs with no luck, I did notice that the I/Cs do not get warm at all, So do I have a power problem? When I select auto convergence it goes through its paces but all the colour blocks are distorted and not aligned at all, Can anyone tell me the maunual convergence alignment proceedure or have a circuit and/or manual.

I am not a TV tecnician however I am a communications tech and have no problem with soldering etc.

Thanks in Advance

Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.

What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Sony Bravia KDF-50E2010 LCD Convergence Problem

Well this is the fix for the usual Ghosting problem....

To bring up the "service" menu, put the TV in standby mode, then press in sequence :

Onscreen Display ( the little screen with the i+ in it )
5 ( channel number 5 )
Volume Up ( upper end of volume button )
Analogue ( middle top button )

The TV should switch on and when it's warmed up, you should see a screen with lots of big green lettering on it.

Press the "menu" button ( middle bottom )

Use the direction dial to move down to "LCD Drivers" and press right on the dial to enter this menu.

Move down to "S H Pos Reg R". It should be "10", change it to "11". ( Left/Right to adjust )
Move down to "S H Pos Reg G". It should be "10", change it to "11".
Move down to "SHPos Reg B". It should be "10", change it to "11".

Press the menu bottom to drop out of the menus, and the standy button to drop to standby. Switch back on, and hopefully your ghosting will be gone hope this works davy mac

Top left side of picture blur

You may have to clean the crt's and lenses and the mirror. Unit may need total convergence from the service menu. If image is blurred in only one area like the corner I would suggest NOT to adjust the electrical or mechanical focus.
