SOURCE: Philips Magnavox 17MD255/17 LCD TV had AC voltage applied.

It seems your "power regulator" a small unit inside tv device has damaged due to wrong power supply. In this case usually the power capacitor burns and few other electronic components like triodes. Get the help of a electronic chip technician to replace the damaged components.

Hope it works.

I would suggest to start by measuring the voltages from the power supply to the main/back light circuitry. If the voltages are low or jumping up and down, that means a defective power supply.
If the red light is blinking, the power supply has a shorted component.
Let me know if you need further assistance.

SOURCE: We had a power outage and the next day all I could get on my TV was the blinking power light. Can you hellp me? I have a Samsung 42" LCD Flat Panel HDTV Model No. LN T4042N edit

Hi, the power surge has destroyed the power supply board that is located inside your lcd cabinet. this board works in conjunction with an inverter board that regulates the raw ac current that is used for many different functions in your set. Normally, this type of damage will be isolated within the power supply but, it could have spread to the main control board as well, depending on how well the surge protector preformed during the surge.

The good news is that, this is a repairable situation. you can replace the power supply circuit board and inverter board as well. these replacements will fix this issue.

please rate and god bless:)

The ware to buy information will be hard to come by hence that manufacture for this product does not use a part number on every single part when servicing the unit. Thus I can recommend where to take it and whom to call for more information since this is a unit that i personally do not repair for my clients anymore due to the aftermarket of their parts and how expensive it is getting them ETC. Here is one solution find someone on that is saling this TV dirt cheap and take the parts from it at your own risk! or you can go the manufacture route by calling this number 1-866-289-5168
I know you came here looking for part numbers and more help then this we understand as experts but to tell you to do something that can harm you or go beyond our scope to get these part numbers, because the part in this unit don't go by that would not help you and us and the cost of the assistance would thus go up surpassing the $9.99. I only can diagnose and check on a solution based on your problem, Yes Fixya does have solutions that do Fix but in the case we can only recommend and I would encourage you to rate my assistance based only on recommendations to solve a solution only,

Thank You

My 42" hd Sanyo flat

chances are your backlight inverter circuit has failed, repaired one a few months back with the same problem. To verify this, take the tv in a dark room. plug it in and take a bright\ flash light and shine it on the screen. turn the set on, you should see either the screen saver or video from your source. If this is the case, your inverter is at fault. Depending on your model, your backlight inverter is built onto your power supply board so you will have to replace the power supply/inverter board. Not hard to do, you can do it yourself with care.

Hello, I have an LG LCD TV Model : 37LC2RR-2L, I can get sound on th tv, the screen is on but no image appears.

You're backlight inverter is faulty.

You first need to check your power supply and ensure you have 24v output to the backlight inverter.

If you lack the 24v you will need to replace capacitors in-line to the 24v rail to get power back to your backlight inverter.
Look for these:

If your 24v is OK then you will need a replacement inverter to restore your picture to your tv.

Best of luck!

I have a 42" Visio

I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the BN_on (on) the backlight inverter and you still have no will need a new backlight inverter.

Hope this helps! Please rate!

Hello my tv don"t have

You have a blacklight inverter issue...or the power (24v) going to the backlight inverter is faulty. You need to open the tv (if you are comfortable with that) and look for popped capacitors...these are usually on the power supply and need replacement for the proper 24v to the backlight inverter.

42" LG lcd tv has sound but no picture

Hello, If there is a complete darkness on the screen, it is likely that the problem is on the card that responsible for providing backlight to the screen. Known as invertor. Sometimes the causes are: 1 loose contacts across the card. 2 the main ic that is number begins with OZ .3 More rarely missing of the 24V voltage that provided to the invertor, in this case you should check the power supply. I hope it was helpful!

Let me know if more help is needed.

Polaroid 26inch lcd tvred standby light on but power wont turn on. I've unplugged the tv, changed the batteries in the remote. The tv stays with the red standby light only.

You need to open it up and checking the voltages in the power supply sections, you should have 5v (for logic circuits), 12v for sound, 24v for backlight inverter circuits. Look for bad caps with bulging tops in power supply also.

Sound is good but no picture

If there is no backlight (check it in a dark room - if there's a backlight the display will be emitting light, albiet still all dark) then you're looking to replace backlight inverter (or two of them, if it's master/slave) OR the power board. To know which of the two, measure the voltage on the cable that comes from the power supply to the LCD backlight inverter board - it has lots of cables but most of them are split in 2 groups - ground and positive usually 24V. It's fairly easy to see which are which, especially on the power board.
So if there's 24V there then it's the inverter(s) and if there's nothing then it's likely the power board; it's a little tricky, though, because the main board may turn off the backlight power - so make sure you check the voltage when turning the TV on from off and watching the read.

If there *is* backlight then you;re looking at replacing the tcon board or, less likely, the main board or, least likely, the cable between them.

Please rate my response if it helps.

No picture, sound only

First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.
