Question about Samsung HLN437W 43" Rear Projection HDTV

1 Answer

TV Screen 'freezing' while watching.

I have a Samsung DLPTV Model# HLN437WX/XAA. My problem is that while watching TV...out of nowhere the TV screen will 'freeze' into a grayscale image. The sound continues. The remote will not turn the TV off so I end up unplugging. I'll turn the TV on again and it will work for a short period of time before it happens again. (The TV has also worked for a long period of time before this happens). What is the problem?

Most likely the DMD board is at fault. If the DMD board is failing it will hold the data lines in the set down which will cause it to stay on until you unplug it. The part number for the DMD board is BP96-00249A but I suggest you have a technician verify the issue and replace the board as it requires mechanical alignment after wards. Please take a moment to rate my answer. Thank you.

I got this tv (Samsung #hln437wx/xaa) used recently as is. I'm familiar with this type of tv as I own a Mitsubishi wd-52628. Problem:Before even powering-up the tv, I removed the lamp checking if it...


There is a power supply that supplies the circuit board plus the lamp, because of hi power there may need someone to look at the circuit board and maybe repair it
Should not cost that much

Cannot view tv program while recording on VCR


Hi and welcome to FixYa,

Initially, pls set the Samsung LCD TV to the Source selection as if watching a playback evgen if you are going to do a recording.

If that does not work, pls postback manner of connection (cabling) from Cox digital cable system to Philips DVD/VCR to Samsung LCD TV LN-T3253HX/XAA .

Good luck and Thank you for using FixYa. Happy Holidays.
