SOURCE: Black screen on lcd

Probably need a Main Board. Take it to an Authorized Samsung repair shop for troubleshooting. T-con would be another possibility and I've even seen the LCD Panel bad on this model

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.4_3_2012_2_04_52_pm.jpg

Look inside at the power supply board to see if puffed up caps like these.

Check and replace the main power regulator board as card basis. It has damaged.

There's a good chance the pop you heard was a failing electrolytic capacitor (they POP when they blow sometimes) either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom (look for discoloration of the circuit board around the base of the capacitor) need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the unit will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.


If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.


If you are handy with a soldering iron and can identify the power supply and/or inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are SURE it's only doing supply output ripple filtering,
and even then, you should go OVER, not under the uF rating).


Most of the caps that go are 10V 1000uF or 3300uF.


I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors, amplifiers, computer power supplies and motherboards, and other electronic equipment.
The parts are cheap, and skill required is minimal.
A great parts source is Digi-Key, and you can order the parts online at www.digikey.com
They typically cost under a dollar a piece plus a flat shipping rate.
The parts usually arrive one business day later.
If you watch the third video, you will see that even someone with no soldering experience can perform these repairs as demonstrated by the woman in the video.

Mitsubichi VS 45609. When I turn the TV on sometimes it comes on and has beautiful picture and sound. Then after 1/2 or so it goes to a black screen. While on the black screen I am able to PIP it and see...


I have the same TV and what is happing is the TV has 2 recievers in it to allow the PIP, So you have a power pack gone on 1 reciever the other is working, Your set has 2 power packs,1 for each receiver.
I had both of mine go, 150$ a piece to have fixed, good luck.

Playstation 2 will load the game, but then only show black screen


You might of had one of the wires connected from the TV to the PS2 damaged and may need new ones or just make sure that the wires connecting each other from the TV to the PS2 are well connected. My little brother use to drop my PS2 a lot too and that happened to me once, but it turned out to only be that the wire got pulled too much when it fell and it disconnected from the TV to the PS2 and I had to only put it in well.

My TV pictures turns black afetr a few hours but I still can hear sound perfectly!!!


It sounds like your rptv lamp is going out. If this is an older DLP this is most likely the cause. You can get a replacement at www.laptopsforless.com part number BP96-00224J for $151. If the tv is still under warranty, I would have them do it, otherwise replace it yourself. If so here is a link to give you step by step instruction. Please give me a good rating. ;-)

Black Screen


Ok, this is probably what has happened, you say that you have played games on your tv, well the thing is with HD and Plasma Screen tv's is that when you play Hi-Res games on them the games backdrop will burn itself into the screen, causing the screen to turn dark and not reveal the correct picture it should. People need to learn about this!!!!! Playing games on HD and Plasma tv's will screw up your resolution!!!
