Question about Samsung Televison & Video

Open Question

I have a Samsung LCD TV UN48J520DAFXZA and the picture has suddenly gone very dim.

I can barely see it. I have had the TV for about 6 months. I can get new circuit boards for $60. Do you think this would fix the problem or should I just buy a new TV?

Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

SOURCE: Sony LCD TV has Dark Picture

Hi there,

the problem is not the lamp.

This model has a set of two backlight lamps, and it is practically impossible that both lamps go faulty at the same time.

When the backlight lap in an LCD TV goes off in this way, the faulty part is always the backlight inverter, that is the high voltage board powering the lamp.

In your case you have to get the TV inverter booard replaced.

Fault with the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Anything new has a chance of failure the first month or so from cold solder joints on circuit boards. If it passes the first month it may last 8 or 12 years. Send it back under warranty.

I have a Toshiba 50HX70... I fixed the convergence issue around 6 months ago. Now the sound does not work... I turn it all the way up and you barely hear anything... I did move it recently, did I know...


Best best would be to try the following:

Start with taking the back cover off of the tv.

1) Verify if you can hear any sound whatsoever out of the speakers. If so, that would indicate that the speakers are still connected to the circuit board. If not, then trace the wires from the speakers to where they plug on to the board.

2) if you hear sound (hiss) in the speakers, but not the audio signal from your program you are watching, then look to ensure all connecters are fully seated around the RCA jacks in the back.

If those two do no produce results, then could be a solder joint on the board finally failed after moving the tv, or the amplifier for the speakers has failed. If you hear sound though as in step 1 above, i would doubt it is the amplifier IC.

Tv picture shrinks


This is a common problem on certain models of Philips Magnavox TV sets. The most common symptom is the screen will shrink and expand over and over. After the TV heats up for a while the video will work like normal. After a few weeks or months your TV will eventually stop working and not have video. You can get complete parts and instructions from www.TvRepairKits.com

Screen stays dark on my KF 60 XBR 800 (FROM 2003)


I think you need to check the high voltage in the damping diode if it is entering the picture tube. If this diode is faulty the tube will not light. you can also check the circuit before it enters the damping diode if there is voltage present.

I have a Samsung rear projection TV, not sure what model number or anything, it is about a 42 inch and about 6 years old now. The problem first started several months ago, basically when the TV was turned...


sounds like the convergence chip. i think you can get a kit from tvrepairkits.com not sure how much it would be to have fixed. But if your good with a soldering iron i think their kits come with instructions as well.

Picture just disappears...


This is a problem that a repair shop must fix. One or two circuit boards must be replaced. Also several electrical connections must be resoldered because they have become loose.
I had the same condition happen to my set. My cost to fix the set amounted to about 350.00. I wish you luck.

that is usually related to the LSB large signal board will eventually need replacement. Most repair shops will not troubleshoot the LSB at component level, they will opt for replacing the entire circuit board. If you need more info or help to locate a LSB board. please let me know.
