Faulty Acoustic solutions TV - no / flickering picture

My model number is LCD26MK750HDF. the problem was that I watch tv from a few minutes to a 30 mins then picture completely goes or constantly flickers. was advised in order to resolve this they would need to replace the display board, but was unable to get the part. Could this be classed as a manufacturers fault so I can get a replacement tv.

You can reasonably make that claim only if a) the TV was in warranty when it started happening, or b) it is happening to so many of these sets that it might be considered breach of an implied warranty (or something like that).

Rca 42in full hd lcd picture flickers


If the picture on your TV flickers, there may be a simple fix. Here are some possible answers and suggested solutions:

1. Your set-top box may need a simple reboot. Unplug the power connection to the set-top box for about 30 seconds. Reconnect the power and turn the set-top box back on.

2. Check all of your cables for a loose connection by tightening each one with your fingers.Flickers can sometimes be caused by bends in rigid cables, too.

3. If your picture flickers to a black or blue screen, you could have a bad set-top box. Contact your cable or satellite service provider about installing a new one.

4. If you still have audio, the flickering could also mean that you have a failing backlight.

For additional troubleshooting information, check out the chart at TV flickering for more solutions. I hope this helps!

I have a Vizio VF550XVT1A. First problem was a flickering screen that ended with the TV turning off. I replaced both invertor boards and the TV seemed to work fine for a few weeks. Now the TV works fine...


Good day sir Alfred!!!!

If your screen turns to back after a minutes but the sounds is normal..That problem is very common to all flat panel specially to LCD TV..

OK,I need to know first if your TV having a back-light when the picture went out after a minutes.If that so the possible problem is T-CON board (this board is the responsible to produce a video on all LCD TV)..

If you don't have back-light the problem is inverter board again..But before you order or install new inverter board try to find why the inverter board gone only on few weeks after you install it..the possible problem why the inverter board faulty for the short period of time is higher/lower input voltages (24vdc) comes from power supply..try to check it using volt meter or multimeter tester..it should be read 24vdc on meter..let me know if the voltage drop or higher to 24..

If the 24vdc is fine the only problem is the condition of inverter board maybe its used or partially faulty when you buy it..

if you have more queries and clarification regarding my solution please feel free to reply on this tread...

Hope it helps..

Thanks for using fixya..

Lost picture on LCD TV


Hi.

Your problem is very lightly to be A faulty invertor pcb.
Relatively easy to replace but you may find it difficult to purchase.

The invertor pcb basically makes high voltage to strike up the tube lights behind the screen.

What make & model is your tv set & what country are you in.
