Question about Samsung LN52A750 52" HDTV LCD TV

1 Answer

Samsung ln52a750 pink green snow and powers off and on

I have a Samsung LN46A650 LCD TV that is 5 old that has recently been giving me trouble. A couple of days ago I come home and turn it on to find that it only shows a green/pink static fuzz effect on the screen and then shuts off (no shutoff sound). After a couple of clicks, it turns back on (making the tun on sound) to show the same picture and the process repeats itself. If I unplug it obviously it stops... when I plug t back in, the TV turns on by itself and does the same thing. No response from the remote either. The problem is that sometimes it does it and sometimes it doesn't... it's like the part that's failing is not 100% messed up yet. I can't pinpoint a situation where it will always do this. Doesn't matter what input I'm in, it might work, and then it will go into this endless loop. (when I was in the TV input and it did this, I could hear the TV's audio, just no picture... well the pink/green ****) I've been checking some info out and have found that there are 3 readily available parts that can be replaced... the T-CON board, the Main board or the power supply (whole thing or problematic caps). So my question is, which one should I replace to fix this problem? Thanks in advance!

It will be best to contact the authorized service centre for Samsung in this case. It sounds to be a main board fault. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience.

SOURCE: Samsung TV won't turn on- trying to fix it. A challenging problem

I had the same problem. I live in NJ and called the local authorized "service provide" listed on the Samsung website. What a joke. Quoted $350 just to show up, never showed up. So I opened my own TV. Took off the plastic back (10 screws) took off the large metal RF shield (12-14 screws) and noticed a blown component. The markings on the component were KL15L and it is apparently an NTC Thermistor. Obviously it got fried and not knowing if there was other damage I decided to set out to replace the entire Power PCB Board Assembly and not the component. There were two part numbers on the assembled board (BN97-00457E & BN94-00622E). After searching online I also found a suitable replacement number for these (BN96-04896A). I found two places who claimed to have the part or have it on order (shopjimmy.com and vancebaldwin.com). After placing orders with both and having neither come through, I broadened my search and found out that the LNR409D was basically the same model as my LNR408D so I looked for its Power PCB Board Assembly part number which turned out to be BN41-00521B. Google search for that part number showed the item available on ebay. I bought it a week ago (ebay 260311519904) for $144 plus $12 shipping. I removed the bad board an hour ago (6 screws about 7 connectors) installed the new one, plugged in the connectors, replaced the covers, plugged in the TV... AND IT WORKS!
Suggestion: If your TV is out of warranty then open it up (what have you got to lose) and see if the problem is obvious and maybe something you can fix (replace) yourself. The parts, spare boards, etc. are out there if you look.

SOURCE: Screen goes completely out.

when it blanks out, tuen the lights out in the room, and shine a flash light at the screen, see if you can see the picture, if you can, it is the inverter moard blamking out, thats the board that lights the back lights, if you cant, hit the input button on the remote, if the TV comes back with a picture, it is a problem with the main board, in paticular the componant input on the main board

SOURCE: Samsung 46" LCD LN46B650 started showing vertical

had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

My samsung lcd tv will only show me black and white when i plug my wii in component 2, how do i make it go back to color?


Your problem may be that you need to select the "AV" input on the HDTV. Samsung HDTVs of late combine the composite video with the green input component video. To use the yellow composite video in the green input port you have to select the proper AV input on the TV which tells the TV to go composite video (yellow) instead of component video (green). Try this, it may work.

I have the same issue. TV is ~ 2 yrs old. Ruled-out cable-box & HDMI cables (green present in menu mode with no cables attached).

Screen turns mostly green, with a crappy picture. After a few days, a normal picture just appeared. Today I powered-on, the green screen stuff came up, then a minute later a good picture for about 20 minutes, back to green-stuff for 10 seconds, then good picture.
