Question about Samsung 52 in. LCD Flat-Panel HDTV

1 Answer

I have a 52 inch Samsung LCD TV and it made a popping noise last night and now it is not working at all. It is only 3 years old and Samsung said that it is not under warranty any more. What could this

I have read online that Samsung lost a class action law suit for 2006, 07 and 08 models due to bad capacitors. I have read many complaints about the same issue on current models as well but Samsung will not honor the capacitor issue with these. Could this be the issue? Of course Samsung said that as far as they are concerned this is "normal wear and tear". I dont watch much TV and it is only 3 years old, how is this "normal wear and tear".

Capacitor(s) could have been the root cause of the problem but unfortunately modern electronic circuits tend to be like a line of dominoes so when one component fails, it rarely fails alone...

You have my sympathy. I enquired at a large local electrical retailer while I was looking around for a new fridge and the lastest huge and hugely expensive plasma screen tv caught my eye. I asked the sales chappie about how long they lasted, about repairs and suchlike. He told me they last about 3 years and no one ever has them repaired - as if I believed that.
Looking around though, few electronic or electrical items have a warranty that exceeds 3 years and many that have more than a one year warranty carry a price premium, though that same retailer would extend the warranty indefinitely for an annual charge. It is in fact nothing to do with the manufacturer or retailer standing behind the quality of their equipment but in reality it is similar to calculating odds and making a wager and in the matter of wagers there are winners and losers, though the casino never loses...

As Samsung have paid for their mistake and seem determined to pay no more, to make any exceptions would be like admitting liability all over again and reopening the floodgates. The only possible way forward would be to obtain an engineer's report and the serial numbers of the affected tv sets.

A modern tv is in fact more computer than tv and contains the same ultra-sensitive Cmos circuit chips as a computer which could have been damaged by a voltage surge a year ago and finally failed last night. Perhaps the problem isn't capacitor related...

SOURCE: Samsung LCD TV doesn't power on, just blinks 5 times

After about 5 years the Samsung LCD televisions backlight fails which prevents the TV from coming on and the powerlight just flickers the backlight can be changed but it is often alot easier and cheaper to buy a new Television

Howdy,
Yes, it is very easy to repair. Solder iron wattage should be at least 300 w.

The PSB is the center Board (towards left) after you remove the back off the TV. Remove the shield that covers the Boards and remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Good Luck, big IRISH.

In almost all cases where the set is taking a long time to turn on and then turning off it will be the Power Supply board that will have bulging capacitors, usually three to five. Look on the upper right side of the Power Supply and look for any blown caps. You can replace these caps and you will be fine. Now the other cause can be the Power Switch is shorting out. You can disconnect the the Power Switch but not the IR sensor and then turn ON the set with your TV remote and see if this stops the problem. If you are not skilled in component level repair on the Power Supply board then buy a new Power Supply board and install it.

SOURCE: my 52" flat panal Samsung LCD keeps turning on and off by itself

that is the worst news you can receive from the manufacturer they pretty much shun you after the warranty has expired its very disconcerting and unfair to consumers I would make sure when you talk to them that the work that was done should have been under some warranty and if it was not the place the blame entirely on the technician who came in and tell them it was at least working to some extent cough cough before they sent someone who broke it even more if after this they dont comply boycot the brand and look for a new or gently used tv

Im terribly sorry to hear about this

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.

TV BLEWUP


What would cause that is failure of some part (probably a filter capacitor) in the set's power supply. The usual cause is component stress due to manufacturers keeping their costs down by using parts that just barely can stand their operating voltages. (Higher rated parts would last longer, but would cost more.) Some parts are just a little too weak and break down. It's not unusual to have this kind of problem these days. The set would be repairable unless there was physical damage to the circuit board itself. You might have it looked at and get an estimate for the repair.
