$50.

Re: Samsung LN46A630M1F too bright/white

Just want to update you all....
I shipped my T-Con to a guy on eBay after confirming he was willing to replace the gamma IC. Received the repaired board in the mail today, popped it back into my TV, and the picture's back to normal!! I'm very happy about that (and only a little disappointed I wasn't able to do the repair myself). Also, I'm grateful to you guys for helping me to diagnose the problem and figure out how to resolve it!

Re: Samsung LN46A630M1F too bright/white

Oh, that's a good idea! I saw a listing for someone offering to repair my specific board for $75, but I didn't think to look for someone offering to repair T-CON boards in general. I like the thought of paying less....

Re: Samsung LN46A630M1F too bright/white

Thanks for the info. Since I have little soldering experience and no hot air rework equipment as recommended [URL="https://www.badcaps.net/forum/showthread.php?p=370433#post370433"]here[/URL], I've decided to just replace the T-CON board. (Thanks for putting me onto that, budm.) There's a [URL="http://milwaukee.craigslist.org/ele/4049017720.html"]local guy on craigslist[/URL] who's said he'll get back to me about whether or not he has the board I'm looking for. Otherwise, I'm thinking of picking up [URL="http://www.ebay.com/itm/121152717078?ssPageName=STRK:MEWAX:IT"]this...

@freakaftr8: Thanks for sharing your experience!

Re: Samsung LN46A630M1F too bright/white

Thanks. I follow the logic of what you're saying, but I have no practical experience doing this so I'm kind of lost trying to find the correct resources. I tried searching for a spec sheet on my T-CON to figure out which ICs are on it....but I failed. Any suggestions? Or should I just start removing the thermal pads on the T-CON to see what's underneath them? I didn't see anything AS15xx elsewhere on the board.

Re: Samsung LN46A630M1F too bright/white

Tom, here are the voltage readings I got on my multimeter....
VGAMA1: 14.84
VGAMA2: 15.78
VGAMA3: 15.86
VGAMA4: 15.19
VGAMA5: 14.80
VGAMA6: 15.37
VGAMA7: 7.11
VGAMA8: 4.99
VGAMA9: 4.51
VGAMA10: 3.59
VGAMA11: 2.04
VGAMA12: 391 (mV)
VCOM: 6.08

Based on what you said about how the readings should be monotonic and how the VCOM reading is expected to be 7-8V, my results support your hypothesis of the T-CON having a defective gamma IC, right?...

Re: Samsung LN46A630M1F too bright/white

Ok - will do and report findings. Maybe stupid question: should TV be powered on while testing?

Hi, and thanks in advance for any help/troubleshooting advice you can offer.

My Samsung LN46A630M1F LCD TV is displaying all input sources and the menu in a global white haze (see attachments). It looks as though someone turned the brightness all the way up, but that's not the case. I've performed both a "reset picture settings" from the regular menu and a factory reset from the service menu. The brightness persists throughout both the PATT_AfterDDR and PATT_BeforeDDR patterns in the service menu's FRCM_Option submenu. I looked at [URL="https://www.badcaps.net/forum/showthread.php?t=25810"]budm's...
