Hi,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Take care in solving the problem because you have to open the back cover of the television in which there are high voltages in the printed circuit board....

Have you tried inserting the DVD the other way round? The label might need to face the other direction. If not, it is a defective DVD drive.

repair or change the power supply board

there are caps in the power supply that goes bad, if you take the back off you can see bulging caps

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

it can be caused by failed power supply due to bad caps, shorts circuits in the backlight inverter boards.

Hello,

your TV is having a power problem. The power supply board is defective that's why the TV won't power up. Its receiving power but it cannot transfer the current to the necessary part of the TV because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the TV might not come on.

If you know about TV repairers, I would suggest that you open the TV and read the power board/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.

Good luck.

try to look for the other parts look for metal bracket the one you mount in the wall.

Unplug,replug it hour later.The tv,will reset it self back to factory.The tv should work now.Not,than the power supply board is dead.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Two places to check, the power supply and the backlight inverter modules.

This could be the backlight failing (most often the images will tend to go pink). If the TV is out of warranty, you can replace the backlight(s) yourself. lcdparts.net has many backlights but you need to match the length and width to the original. Next you need to open up the back of the TV and carefully remove the old backlight(s). The backlights are on the perimeter of the TV (laptop screens started with one but most TVs have several to maintain an even lighting of the image).) The removal takes some work and paying attention to how the original is put together. The backlights are often molded into the frame of the TV and a Dremel or other rotary tool is needed to get the backlight out. Google backlight replacement for videos, pictures and descriptions of the process.

I hope this helps.

Interference! Check that your antenna is stable and that the coax is firmlty attached and has no breaks from wind friction or is under a loose nut and moving when the wind blows or a bird sits on one of the arrays. It may also pay you to check the TV end of the coax as well to see it is intact and not a loose wire up inside the pin. The sound from speakers can cause coax to vibrate and then the wire loses contact with the pin. It may need resoldering.

Please rate my help++++Thanks for using FIXYA

Hi


Thanks for using FixYa. Blinking red light means that the power is getting to the unit however, as its not working which means that the power board should be checked. To start with open the back of the unit and then check the power supply board for any bad (bulged/swollen) capacitors. Power supply board is the board where all the power cords/plugs goes into. After you have checked that also check the main board and if you can use a multimeter to test the components on these boards. All this should only be done if you have knowledge of internal circuitry of the unit as the components consists high voltages even when in off position. Please do accept the solution if the issue is resolved or post a comment for further assistance.



Thanks

I recently bought a used LCT2060 that had no remote. I figured my comcast cable remote would work without a problem but it didn't. So 3 universal remotes later I found my solution...a radio shack universal gamer remote. It controls up to 5 components plus your xbox360, playstation and pc. The price on sale was a mere 12.97, not bad if you ask me. Hope this helped. The code that worked for the Akai was 11676. Take care...

The blinking light is the led I assume u meant..?!..if so then here is the problem The caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once insidet here will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol! ..If this helped you (or not )please rate, thank you!

Hi i bought mine at home depot for a few dollars they were very helpfull there and they worked great...

M6X45 is a standard metric size, M6- diameter, 45(mm)-length

The problem is with the power supply section of your TV set. Please take it to some good service engineer. There is nothing you can do yourself.
