Our LCD TV which has been stored in original pkg, used less than 10 times and only 6 mos. old is out of 90 day warranty. We called Memorex Cus Svc and there is no replacement part for the problem.
The screen is very dark, although you can see slight blue image if you tip screen just right. I have opened the tv and can see that there is no bulb or background light to replace. Hate to scrap, TV cost $220.00. Although, dont want to spend 100.00 plus to repair. Any recommendations? Please help
I have the same issues with my Westinghouse LCD set. I've found that going into the settings (using the TV remote) I can get it back to a bright picture by selecting 'restore factory settings'. It is aggravating and a pain, but I can correct it.
It only seems to do it on the analog stations, not the digital (HD) ones, so maybe it will go away after the conversion next year.

The tv LCD screen panel itself it is dead,by force.Sorry,no not repairable.Only way to repair this tv,it is to replaced the whole LCD screen panel itself,not practical or possible because the LCD screen panel it is mission impossible to buy as a refurbish items,only can buy it from tvs manifacture itself only,but it 90% important to the tv and it functions and it is very limited production items,so they'll sell it to u,but the cost it is the same as a new tv.Buy a brand new tv it pretty cheap these day at Walmart stores.Tries buy another tv same make and model as ur old tv.Save the dead broken LCD screen panel old tv somewhere for later years,as refurbishes electronic PCB boards for ur new tv later uses.
LCD TVs are side lit with either cathode tubes or LED's (depending on the model). This saves space and allows the TV's to be so thin. The newer LED TV's are backlit, so there is an array of LED behind the screen, but because your model is side lit, most likely with a cathode tube, that the tube is on it's way out and takes an excessive amount of time to warm up and get to full brightness. You culd try looking up a part number through LG, but my guess would be it's expensive and not easily replaced. Perhaps contact a local electronics store to see if they ofer repair service and see how much it costs versus buying a new tv.
This problems can't be repair sorry.The problems u have is the effect of the LCD screen panel itself shorting out.The LCD screen panel is slowly getting darker and darker eventually will ingorf half of the screen or more.Than the evidence more clears is not the tv electronics,but the LCD screen panel display itself.Sorry the LCD screen panel,replacement is not an option,because it is 90% inportant to the tv and it limited production by the tvs corporations and only can buy those LCD screen panels from the tvs corprations themselves.They'll sell the LCD screen panel price the same as a new tv.Sorry this tv now,dosen't worth as a whole tv anymore,now it only can be used for as eclectronic boards for salvaging for boards to used as parts,that it.
that is a factory defect you call the dealer for the warranty.the defective part of your tv is the inverter board.this board supplies high voltage supply to the backlight cold cathode flourescent lamp.This lamp is the one illuminating the screen of the tv..the lamp is installed at the top and bottom of the screen thats why the center of the tv is dark because the lamp does not lit well..tnx
I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.
Your tv is being attacked by electrical surges which seem very violent and has already damaged some logic controls. Please invest in a AC filter which will protect your tv from such spikes....... but first you need to get your tv serviced from the electrical damaged it has already suffered.
Thank you for your response. After calling the manufacturer, it was decided that the problem is with the cable co. and not the TV.
So, we have a cable technician coming to check it out in a couple of days. Hope he can fix it!
