Question about Samsung Televison & Video

Open Question

Dimming I have a 22 inches Samsung Lcd tv. This is a gift to my child and i never used and pay attention on it. Recently I noticed my son unplug the power cord and plug it back too often. I asked him why he did that, my son told me the tv get dimmer after a while and he needs to unplug and plug again in order for the tv to work . I was shocked when my son told me this happened since the tv brand new. I have the tv for 3 years, if i have known this issue happened at the very beginning i would have returned it. Please advise as why the tv would get dimmer and turn dark after a certain period of time. Thanks so much for the help. Mag

SOURCE: Hyundai LCD TV HLT 3010 Pictue suddenly turns black but has voice

This is quite a common problem on LCD televisions.
It is not a fault you can repair yourself unless you are a competent electronics engineer.

One of the transformers on the inverter board will be the cause as the tend to go open circuit. Being surface mounted adds to the dificulty of changing this item as well.

SOURCE: Samsung LN-T3253H LCD Sound Problems

PEOPLE, YOU NEED TO GO BACK TO THE STORE, BUY THE SAME TV AGAIN, SWAP THE TV'S AT HOME AND RETURN THE "OLD" TV IN THE "NEW" BOX WITH THE NEW RECEIPT. IN THE CASE OF TOO MANY RETURNS, HAVE A FRIEND, MOM, DAD, SISTER, GIRLFRIEND TO BUY ONE FOR YOU AND DO THE SWAP LATER.
NOTE: I REALLY HATE DOING THIS TO THE STORES, BUT IF YOU PAY FOR SOMETHING IT SHOULD LAST LONGER THAN 30-40 DAYS. PROBLEM SOLVED! :)

SOURCE: Panasonic 32 inch LCD TV will not turn on-red light flashing

The number of flashes is an error code. Count the number of flash. It looks like one of the boards in your set is failing intermittently. Panasonic codes for a guide as a starting point. Exact board STILL has to be verified;
One Blink: One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in the field. Therefore a replacement is required.
Three Blinks: Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Five, Seven, or Eight Blinks: The A board is responsible for five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.
Four or Six Blinks: The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board. The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.
Nine Blinks: Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.
Ten Blinks: Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of the power LED requires the replacement of the A board.

SOURCE: Bottom half of the screen is black on Samsung HP-R5072 50 in. HDTV Plasma Television

I have a solution. My Samsung plasma had the same problem with the bottom half of the screen being black. Follow these directions and it will not cost you a dime, just some time. I took the back panel of the tv. I found the lower buffer board on the left hand side. I disconnect all the ribbon cables. Use an air cleaner to spray out any dust on the ribbon connection and the board. I connect the ribbons back to the board. My plasma is now as good as new. If you have issue with the top portion, do the same with the upper buffer board. I was going to buy a new tv but I'm glad I gave this a shot first. It's been almost a month and it's still working fine. Hope this helps and hope it saves you some money.

UNPLUG take the back off and you will notice 3 to 7 capacitors on power supply swollen and/or cracked. Replace with same values and make sure the replacements are 105 degree capacitors so youll have longevity in the repair.....

When i turn my monitor on it shows no picture and it makes a sound like it is running the electricty went out and when it came back on thats when the trouble started thank you


It's time to spend $100 to buy a brand-new 19-inch LCD monitor,
or $200 to buy a brand-new 22-inch LCD monitor,
rather than paying a TV/CRT technician $50 to $75 per hour to try to fix the "antique" monitor.

Samsung 52 Inch LCD 120hz. 3 inch wide vertical line on screen


This is a problem with the LCD panel. If the tv is out of warranty, I would call Samsung and see if they will pay for the panel and you pay for the labor. The panel is not cost effective to repair. If Samsung will not do anything you will need to buy a new tv.
