This is a how long is a piece of string question. You don't provide any details and expect an answer. All things can be fixed. On average problems like yours ( No picture) cost about $800 to fix if the sustain and power boards are involved. But in this case it's all guesswork

Thanks for using FIXYA

I bought tv 19/4/16 and the screen has gone all crackly got sound but no picture


It sounds like you have broken the display panel. This is really expensive to repair. If you get lucky, you can find a other broken tv with good panel and broken circuits to use your tv circuits to fix that screen (board is lot simpler to replace than panel). Usually it's cheaper to buy a new screen, sorry for your loss...

PS. Working TV circuits are quite something worth. You can sell the boards for getting money for the new screen.

How do i fix my 50 inch element lcd tv has picture that is half blue and half picture


you cant
its most likely that the lcd drivers attached to the lcd is shot , its because lots of these tvs have no cooling fans so the solders become brittle. or some one hits the front of the screen an it will damage them.
its a trick to fix them if its even possible
other wise the video board has gone south from some capacitor thats dried is 2nd choice.
id not wast the money fixing it because your guess would be wrong most likely.

I have an LG Golden eye tv which was bought 10 years back, now the video is suddenly going off and the screen is black at which time the remote control also does not function, but the audio will remain...


The device called LOT (Line out Transformer) inside the TV has gone weak. Call a TV service engineer and he should be able to repalce the LOT to fix the issue. Also ask him to give a report on the life quality of the picture tube.

Turn tv on has sound and picture then picture goes out and the red light comes on with fan


The red light usually indicates a power section problem. It would be something just about gone or overheating.

You will have to take this into a repair shop or a Phillips repair depot. You really should get an estimate for this before commiting to getting it fixed. Depending on the year it may have a sperate power board (cheapish to fix) or might require the main board to be fixed (lots of $$$) Worse case is that it can cost as much to repair as just buying a new replacement tv. So get the repair estimate and check around for replacement costs and let that be your guide as to which way to go with this.

The colours on my tv have gone pink and green


Either your picture tube has gone bad or the transistor or IC on the crt board, on the picture tube, that feeds the blue gun has gone bad. You would have to test the transistor to see if its shorted or open with a multi-meter, or check the voltages to and out of it. The voltages are around 200v and dangerous if touched, best left to a proffessional. If its the transistor/IC it would be a cheap and easy fix by a repair shop, if its the tube, you may want to go tv shopping.

Screen has a little scratch there is sound but on picture with little thread lines coming form the scratch


you likely need a new tv. on the insides the audio pieces are a lot tougher than the delicate pieces that create the picture for you. if it was dropped and something hit it and it cracked losing your picture, I am pretty sure the tv is toast.

No picture, standby light blinking


MOST LIKELY THE ERROR 3 IS THE 200V LINE TO THE CRT DRIVE IC.IC702. ON THE CRT PC BOARD. IT ALSO COULD HAVE GONE OUT IF YOU HAVE HEAVY USAGE ON THE SET 8-12 HRS A DAY. THE CTR COULD SHOT AND TAKE OUT THE I.C. AS FOR IS IT WORTH FIXING, THEY DON'T MAKE CRT TV'S ANY MORE AND THE NEW SETS SEEM TO HAVE A LOT OF PROBLEMS.
