Follow these steps:

When it asks you to enter the code for your tv use 10178

It works like a charm!

Start mashing the input button, see if it's just on the wrong one.

Your signal board is bad and will need replacement. If you open up your tv and look at the signal board you can get a part number so that you can order one.


You can get get parts for this tv at www.interliquidparts.com

Hi sorry to tell you but it maybe almost anything honestly, that question is like asking "How long is a piece of string?" it's simply impossible to answer.... As usual you need to obtain a service manual, start at the power supply and work out, as an aside here i usually use Freeze spray when looking for thermal faults, but sorry there is just no easy way nor shortcuts... it's simply a matter of taking the voltage measurements starting at the SMPSU, and then finding the faulty "Rail" and work along that/those and find the problem, that or replace the board(s) that any faulty components are suspected to be on.

I give you a link for a training manual, this may help you understand what and how do do things? I have been unable to find any service manuals, perhaps an approach to the manufacturer will yield one, or a better 'net search?

Hi, well I applaud you for wanting to have a go and try to repair you set. But PLEASE, start in the right place, otherwise you will simply waste your time and money, You see, you MUST start, in the right place, The power supply, FIRST, as, if, that isn't right, nothing else can be. But you simply cannot do anything without a Service Manual. In this it has everything one needs to repair the set. OK if it is shutting down, after that amount of time, of working and then faulting, then it is most definitely a "Thermal" problem, the way we "Find" problems such as this is "Freeze Spray" you use this on each component that is suspected of being the "Culprit" and you will soon,find that errant component. Now, also not every fault is a Capacitor, I see many, many people that think, that Capacitors are always the "Culprit" and replace them, because someone else had done so and it worked, well that maybe sometimes true, but most Symptoms, can, and do have many, many different "Causes" & also, now while that may be true in a few cases, a faulty Electrolytic Cap, or even, ordinary, Cap goes faulty, this is only a SYMPTOM, something has damaged those caps causing them to "Fail". One MUST always find the root "Cause", otherwise if you just treat, the SYMPTOM, the "Cause" will just make the "Symptom" come back, in short order, as the prime cause still, hasn't been fixed., Now Capacitors hate AC ripple, or Over Voltage. Thats it. Oh.. and Heat, if these Capacitors, are too close to a Heat Source, then thats a prime cause of failure. Resistors, hardly ever go faulty,and if they do, it is generally obvious. However it doesn't hurt to check values with our Multimeter. Remember though resistors are made, with up to 20% tolerance from stated value, as such, are not too critical, unless in Timing circuits etc. Always check, the Values, of resistors, as with any other component, with the power OFF. Now Diodes especially "Zener Diode", are another thing to check, those and ordinary "Signal Diode" should always be suspect. next we have Transistors and IC's. The Transistors MUST ALL be checked to see if they have a good, "Junction" this is done, with our meter set to "Diode Test" and usually are about 0.6 to 0.7. With IC's you must check, voltage levels, or Logic Levels, going in and out, have a look at the circuit diagram, and it will tell you what they should be. It is a good idea to always measure the Power Supply voltages, see if a "Rail" is Low, that will be because some component has gone somewhat or all short circuit, to Earth, now, if the "Rail" is Higher, suspect an "Open Circuit" component, like a Diode, or Transistor. The voltages expressed in the manual are spot on, ANY variation MUST be investigated. I have been doing all this for over 30 years now, and I do indeed wish, we could have a set of "Symptoms" and be ables to say.. "Oh that;s the so-in-so and replace this" however unfortunately this although does happen, most "Symptoms" can have literally tens, of "Causes" all often "Interlinked" One simply has to do a methodical troubleshooting procedure, and always think, "are my Voltages Correct" as this is how, you Fix the problem, by making them so. Keep up the good work. If that link above doesn't furnish a Service manual, it is imperative you get one, even if you must pay for it. It will pay for itself in about 2 mins.

So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else

You may need to change your audio output settings in your menu.

Good day!! That problem is usually cause of bad/faulty capacitors on the power supply board..So you have a better chances and easily locating the faulty capacitors if it is look like leak/bulged on the top.. So please try to follow this instruction on how to do that.. 1. Open the back cover of your TV. 2. Look at the power supply board..Its normally connected to the power cord.. 3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors.. 4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value.. 5. Some of the capacitors not bulged so its better if have a capacitance meter.. Hope it helps you..

The tv LCD screen panel go black blank,but dose the tv still have audio sound of the program?Yes?The tv have 1 or 2 a long boards that are called a LCD inverter boards.It is dying and require replacement.These 1 or 2 a long LCD inverter boards only job are to provided a backlight for the tv LCD screen panel to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy those 1 or 2 refurbishes long LCD inverter boards for the replacement.

Such problem is caused by a loosened terminal in the power supply board. Open the back cover of the television and locate the power supply panel. Check the PCB for loosened terminal and have it soldered by a soldering iron.
