Question about Televison & Video

3 Answers

One year out of warranty and the tv set developed and intermittent problem, after turning the set off, the standby led went off. The tv would not come back on. Finally after many attempts the tv returned to life. The problem persisted for two or three weeks. Then one morning, I tried to watch an HD program, the tv powered down and the standby light also went out and has not been able to be turned on since. I have heard of many reasons why an LCD tv would react this way,:cold temps, hot temps: and I don't know what to be true. The temp gets cold here in GA but not below zero cold. I have assumed by reading post about this particular manufacturer that this is a power supply issue.Basically the tv will not come back on.

Hello There.

You haven't mentioned which manuafacturer it is but Panasonic are well known to have a similar problem, and yes it is a Power supply problem. In particular it's the IC on the Power supply circuit board, but the solution is a new power supply.

Hope this helps.

Yes, sometimes during a cold day or night, condensation will build up and deposits moisture threw out the set. if this is on the power board, it will cause a short. i suspect a typical burn out of the power board. the capacitor's may have been fried. i would replace this micro board and its components.

Hi!

Yes it;s a power supply issue and you need to check out for the capacitors and any other burnt components on the power supply board. Also check for any loose connections if you have opened the TV

TV comes on to standby, but with record led flashing. pressing power on , power light turns green for 1 second, click from within unit, back to standby with record led flashing


Hi,

Initially, have you tried a full hard reset? If not, pls unplug from the mains. Most current devices would reset and revert back to factory default settings (assuming no internal hardware fault) when unplugged for a considerable period of time (a couple of hours).

Pls post back for any development(s) or even the lack of it.

Hope this be of initial help/idea. Good luck and kind regards.

Thank you for using FixYa.

Samsung HC-P4752W Does Not Turn ON


The proble you have is an intermittant power supply or sweep power supply. Unless you can find a bad connection on the power and deflection board, this could be a very difficult problem to find. I have ran across this problem a couple of times, and after spending countless hours troubleshooting, I replaced the main board and all the problems were taken care of. The board part number is at samsungparts.com and I found the board for you. it is located here: http://www.samsungparts.com/part_detail.asp?catalog%5Fname=Parts+and+Accessories&product%5Fid=BP94%2D01266A&search%5Fmodel=HCP4752W Good Luck

Hi! My toshiba 2100td tv is over 10 years old and last few years it's having weird problems. When it's turned completely off (not in standby) and when I turn it on, the screen blinks for a 10-


The real problem here is its age, a lot of these sets of that age critically needed parts are just no longer available.

I repair them but the real risk is someone fixed it, a few months later it develops another problem etc etc etc.

Ten years is now a days a long life for a TV.

When I turn the set on green leds appear for about 30 sec then it swicthes to red stanby and flashes 5 times intermitently


Hi,

May I know what is the exact model number of your TV, it is located at the rear cover, manual, and on the receipt. It will help diagnose accurately where the fault came from and confirm the blinking error code.

Samsung 55" LED UN55D6003 Intermittently turns off and on...T/S help


DO NOT ATTEMPT ANY REPAIRS, CALL THE FACTORY PHONE NUMBER IN THE OWNERS MANUAL AND FIND OUT WHERE TO HAVE THE TV SERVICED, IF YOU ATTEMPT ANY REPAIRS THEY WILL VOID THE FACTORY WARRANTY. THIS IS CAUSED BY AN ELECTRICAL FAULT INSIDE THE TV, IT SHUTS DOWN AS A SAFETY FEATURE TO AVOID ANY FURTHER DAMAGE.

Sanyo 25DN1 standby problem


I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need a power supply module. If the problem is more than one of the circuit boards, the price of repair could go much higher. I would not suggest or recommend trying to repair the TV yourself.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.
