Re: samsung LN-T4661F Negative image & intermittent ghosting

Hi there, just wanted to post an update. I ended up just taking a chance & replacing the TCON board and it solved the problem. Thanks for your help!

Re: samsung LN-T4661F Negative image & intermittent ghosting

Welp, the customer finally brought the remote. Despite doing a reset and verifying all the settings I could, no luck. I'd try flashing it, but I have not been able to find any firmware files for this model. Tomorrow I'm going to disassemble the unit and try to test voltage on the TCON. I think I'll need to do some more research on that, as I'm not as familiar with that board as I am with others. It sounds like the aforementioned chip is a common point of failure, so I suspect there is some info I can find. Thanks for...

Re: samsung LN-T4661F Negative image & intermittent ghosting



Thanks for the tip! It has a Wiselink USB port that can apparently be used for updating firmware. That led me down an interesting path. While hunting for the firmware, which I have not yet been able to find, I've found some threads indicating severe (though correctable) image issues arising from firmware updates. Now I'm wondering if someone has attempted a firmware update which resulted in these issues and just decided to offload it on someone else. Before I disassemble it I think I'm going to get...

Thanks! I'll disassemble it shortly and get to the TCON board.
In researching the issue, I did see some info related to that chip, but it was for a different model. If it pertains to this model as well I'll make sure to do some more research.

I am working on this for a customer, so sadly I can't guarantee the TCON board has not been replaced previously. In addition, it is now on its 2nd or 3rd owner. The story is that it just occurred.

Hi all,

I've got a Samsung LN-T4661F that has what I would describe as a "negative" image. It also intermittently retains images on the screen (ghosting?). i.e. If it sits on the DVD menu for a bit, then you transition to another screen, you can still see the DVD menu. (This isn't consistent.)

All HDMI inputs have the same behavior. I have not tried any other inputs yet.

At the moment I'm thinking that the display/main board is the culprit, but I haven't ruled out the TCON board. Power is good, & it's not behaving like other tab bond issues...

Re: Polaroid TLX-04244B Image, but no backlight (No separate inverter boards)

Thank you for the response! I know pictures are important. I'm sorry, I have a fine motor tremor (I shake somewhat badly all the time) and so my pictures all turn out nearly useless, especially when detailed things need to be identifiable. (One reason I went a bit nuts on describing things.) I was thinking that this seems to be a common problem with this set & I suppose I was hoping someone familiar with it would chime in. After looking over some of my questions, like the one about freakin' DIP switches...

Re: Polaroid TLX-04244B Image, but no backlight (No separate inverter boards)

Did I provide too much information? :/

TL;DR: Replaced bad main board. Now have image, but no backlight. Do I have a bad power/inverter board or bad backlight/s?

Hi all, long-time lurker, first-time poster. I've been fixing TVs for a while now, but I don't have all the answers by any means. You guys have all been a big help, and I'm hoping someone may have some feedback for me on this one as I'm a bit stumped. Thanks in advance for your time!

I have a Polaroid TLX-04244B. It was having one problem, I attempted a repair and now it is having a different problem.

Initial situation (Essentially solved, apparently):

- When turned on, red standby light flashed repeatedly (no sequence)
- Had to unplug it...

Hi all!
My name is Oran and I like fixing things. I primarily work on computers, but I've been taking apart anything and everything for 30 years. This forum has been a great help to me as I delve deeper into TV repair. Thanks everyone!
