20 Most Recent Samsung LN32A450 LCD Monitor Questions & Answers

I agree with Terry. But in most cases the LCD part is almost as expensive as the whole unit so replacing it really is not the best option not unless you find a used part somewhere in E-Bay or a local shop.

Your screen has plastic holders for the connectors they might be loose open the screen and put metal or cardboard to secure the connectors see youtube there is alot info on that search repair lcd screens

Probably the power surge damaged it. Surge protectors can only absorb so much of a single surge or multiple smaller surges fried it.

This TV does not support Closed Captioning, However, you may be able to enable it from your cable box if you have one. To do that you may need to contact your cable provider. Most of the times its a simple option in the settings. Alot of times CC comes pre-enabled on the cable box and all you need to do is press the CC or Closed Caption Button on the remote.

Hi there.I have written a very helpful tip about this problem recently.Check it out here: http://www.fixya.com/support/r9352105-fix_colored_vertical_lines_lcd_display

You need to inspect the power supply first, look for blown main AC fuse and any bad caps with domed tops, see example of failed Samsung TV here:

Hi ldmsdad_05,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the dried-up/leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit and blinking error appear. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Also, bad solder joints can produce the same symptom, it is hard to spot, you should use table lamp/portable lamp for finding the cold solder. Secondary reason of fault is the open fuse/fusible resistor in series with the output of regulator IC/transistor, shorted/openRegulator IC/transistor, shorted zener diode(all are in the power supply section) and the microcontroller. Best that you check the output voltage of each regulator to determine where the fault came from and narrow the job.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Get it fixed under WARRANTY ASAP! It will be real expensive to have it repair, it can be due to bad main board or T-CON board.

Try unplugging and plugging it back in. Was there lightning, and was it attached to a surge protector?
Try pressing the power button repeatedly or even slapping the back of the tv (try googling this).
Good luck!

You will need to open it up and take a look inside. It may be still under warranty.

Service manual:
http://elektrotanya.com/?q=showresult&megnev=SAMSUNG megnev2% 20 & = & Category = & LN32A450 kat2 = all

if the line is vertical it means the LCD panel is defective or a contact to it is loose.

If the standby light flickers off every 5 seconds or so, see the solution here

This is probally a fix for a repairman. Probally a bad video card or power supply board. It is probally not going to be cost effective, You are probally best off buying a new one.
