If you need more advice then what has been provided then it is most likely you don't have the expertise to tackle this job yourself. I would recommend you just have it serviced or for 250$ you can buy a 20 inch television brand new with a warranty.
Hope you find this helpful keep me updated.
Thanks,
Lee

Here are the specs for the power supply, match them up and you will be fine. Sears Parts Store will probably have one otherwise the manufacturer would, if you are having trouble getting one, let me know.

Power Power Device: Power supply
Voltage Required: AC 120/230 V ( 50/60 Hz )
Power Consumption Operational: 90 Watt


It isn't hard to replace but will require some knowledge of electronics, let me know if you need help with this when you get the part. good luck

You can get power supplies at a fairly cheap price at surplus shops near your area. Everything in surplus is relatively cheap and relatively dependable. As for installation, that will depend entirely on you, how well you can replace and reconnect wires as needed. You'll have to open it real slowly and carefully, making sure not to force anything out of place. Steady as she goes. You shouldn't need much equipment, a soldering kit will do fine with a pair of pliers and perhaps a small range of screw drivers. Keep your distance when plugging it back in after you've fixed it, just to be safe. :) let me know how it goes.

    Bro you'll probably get electricuted if you attempt to do something you no experience with. I take back what I said, because I refuse to put your life in danger. Paying 250 won't be as bad as paying for any potential damages that may occur if you reconnect some wires improperly, which could start a fire or a small explosion.

Greetings,

If you know electronic stuff, check out the power supply section.
Replacing the power supply is another story, it is not just like swapping cartridge (soldering stuffs will be needed).

Have them replace the power supply, it is worth the hassle.

Keep us posted and thank you for using our service.

No power, no blinking lights for my panasonic th-42px60u TV. I bought my TV new about 7 years ago. I have had no problems with it until today. I was watching a program I heard the click I normally...


the power supply inside the tv, is what it sounds like to me. I fixed a 50 plasma about a year ago that all it needed was a 20 cent capacitor. but you might find the power supply for yours on ebay for kit 20 bucks or a used board about 50. this is not a for-sure fix, but if you can fix it saves you about $300+ just be careful when working on it you dont crack the screen.
the one I fixed was a first generation plasma flat screen tv and it price was about 10 grand. I love it it still works good and has a nice picture.I have the most expensive TV on the block ! it likes it's power though 500 watts .
So in summery, the two things I have found over the years in my "look what I found honey" tv projects is that the power supply has failed or the screen light driver needs to be replaced. in the last 30 years I have only purchased 2 new TV's and fixed and gave away to friends about a 100. and that was before I had internet and parts had to be hunted down by catalogs and phone,
SO go ahead and try fixing it, if you cant fix it Give it to your local TV repair shop for parts, he might help you out in the future if you need parts, to fix another stray you bring home ?

T.v. will not come on model LT 2327


This is either a power supply problem, or, as I suspect, the capacitors are blown out on yuour screen. Alot of screens nowdays are having this problem, as they come with capacitors to energize the screen, and the capacitors are coming from China and Taiwan, with low quality standards. The caps should last between 15-20 years before going out, but on alot of these tv's the caps are burning out in about 18 months to 2 years. If your tv is still under warranty follow the warranty instructions for repair, if it has no warranty, or if it has expired, then take it to BestBuy or Fry's electronics. They both have special technicians for this type of service. Just Know that it is not cheap, as the repairs can sometimes cpst as much or more than the cost of a new TV.

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Most likely the TV has a power supply related problem. The most common problem are the power supply for the screen itself. Most manufactures call it a Backlight Inverter Board. Something you may want to look at for your problem. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.

TV is dead. No standby light, no power light. We left for the day with the tv turned off and 6 hours later we found the tv dead. Any ideas would be greatly appreciated. The tv is about 2 years old.

LCD TV Remote quit working


Hi,
First thing, turn off the TV and unplug it for about 2-3 minutes. Remove also the batteries on your remote. Re-install the batteries on the remote and plug in your TV. Power on your TV using the remote. No luck?
Norcent may not be supported by a universal remote. If you just bought your unit new (maybe Best Buy who carries this brand) you are still covered by its warranty. Below are ways you can reach Norcent.
