i have one lcd tv in my bedroom i have had it 2 years just after it went out of guarantee the screen went blank the sound was still there but no picture i had an tv repair guy have a look at it he said it was the screen inverter but the tv was too new at the time and the parts were not listed he quoted me at least 150 to repair if the parts became available.i have since bought one off ebay from what seems a reputable company however after i have installed it which was pretty easy the same fault has occured.now im led to believe the fault lies in the "t-con"board now i dont fancy spending more money in case it is not at fault .now what i need is a good person to guide me through the elimination process .i.e how to tell if the inverter/t-con boards are working correctly .thank you in advance..the tv in question is a beko 32wla520hd

If you hold the screen at the right angle against a lamp you should be able to see an image in the monitor, albeit very dark as its not backlit. If its like that, its either the inverter or the backlight itself. Only way to prove either way is to test a known good part.

Have you replaced the inverter? Or is that what that "T-con" board is supposed to be?

[jim2311]

You said "the same fault has occurred" after replacing the board. Do you mean there was no change to your symptoms or did it work for a period of time then the same fault appeared.

thank you for the replies i have replaced the screen inverter with the same fault still there.what i want to know is this.when i switch the tv on,inside i see the flurescent tubing which the screen inverter powers,they light up as does the screen but no picture,if the inverter was broken would these lights be still visible is this a sort of stand by lighting so to speak does the inverter do anything else apart from lighting the tubing behind the lcd panel.i hope you understand what i am trying to say lol.i havent replaced the t con board as of yet that will be next i think but need to be sure i can get pictures if need be thank you...

Why didn't you just take it back to the shop you bought it from ?

If they tell you your guarantee has expired - tell them to balls.
Any item you purchase within the UK automatically carries a 6 year warranty by law.....


The Sale of Goods Act 1979

The Sale of Goods Act lays down several conditions that all goods sold by a trader must meet.

The goods must be:

1. as described
2. of satisfactory quality
3. fit for purpose



As described refers to any advert or verbal description made by the trader.

Of Satisfactory quality covers minor and cosmetic defects as well as substantial problems. It also means that products must last a reasonable time. But it doesn't give you any rights if a fault was obvious or pointed out to you at point of sale.

Fit for purpose covers not only the obvious purpose of an item but any purpose you queried and were given assurances about by the trader.

If you buy something which doesn't meet these conditions, you have the potential right to return it, get a full refund, and if it will cost you more to buy similar goods elsewhere, compensation (to cover the extra cost) too.

Note, however, that the right to reject goods and get a full refund only lasts for a relatively short time after which a buyer is deemed to have 'accepted' goods. This doesn't mean that the buyer has no legal redress against the seller, just that he/she isn't entitled to a full refund.

Instead a buyer is first and foremost entitled to have the goods repaired or replaced. If these remedies are inappropriate, then you're entitled to a suitable price reduction, or to return the goods and get a refund (reduced to take account of any wear and tear).

The act covers second-hand items and sales. But if you buy privately, your only entitlement to your money back is if the goods aren't 'as described'.

If goods which are expected to last six months don't, it'll be presumed that the goods didn't conform to the contract at the time they were bought, unless the seller can prove to the contrary.

In all other situations, it's for the consumer to prove their own case (that is, that the problem existed at the time of the contract). This will prove more difficult the longer you've had the goods. Subject to this, a consumer has six years from the time they buy something in which to make a claim, irrespective of how long the goods actually last.

How many CCFL tubes does the tv have? like how many plugs come out of the panel that go to the inverter?

You can buy Universal inverters, just solder a 12V Ground and 5V on/off signal and that will fix it.

I picked up a 19" technika hdtv and fixed it this way

PS I would never touch Beko tv's ever again. A friend of mine got a CRT one years ago and it lasted a week, the replacement lasted 2 days and the third smelt of burning.

WRONG!.....and I say this, as I feel my 20 odd years working in retail would qualify me well enough to know better.

What is true though, that the product should have a reasonable expectation of lasting long enough to justify purchase price, and that limitation is set partly by the sale of goods act, and partly by the statue of limitations act (The latter I am actually using right now, to reject a debt collections company demand of payment, as their claim appears to relate to an item that was last acted upon over 6 years a go).

The problem is though, is the costly lengths you have to go to, to prove your point, as most retailers will force you to go via small claims court, as a CCJ is not normally enough.

Sorry for not being about much..

Hmm yours has 4 transformers so I assume 8 outputs? mine had 2 trans and 4 outputs so im basing my assumption on that.

Your board is seperate from the main PCB so it would probably be easier for you to buy a replacement board. if you cant find a spare based on the Tv model number google the part number on the inverter.

It could just be a faulty Transformer on the inverter board but if one thing has blown leading to the transformers going a replacement transformer is just going to blow agin.

The only other thing you could do is buy the same tv but with a smashed LCD panel but working otherwise, broken LCD tellys seem to go for mere pounds on ebay
