20 Most Recent Proscan 26LA30Q 26 in. LCD Television - Page 9 Questions & Answers

Hi, As far as finding replacement inverter you can do a search via google to see what you find. However, the inverter can be built into the main board of the TV, which would require you to replace that. I found through a quick search that the main board can be had for about $30. http://tvchopshop.com/all-tv-parts/proscan-plded3996a-e-main-board-3393a-zp-vst-3393-a-refurbished/ It could also be a power supply problem too, bad caps, as well as the backlight itself. It looks like you could contact the above site and ask them the typical failures of this TV for the symptoms you are seeing. If you consider yourself experienced with electronics repair, you could repair it yourself. Otherwise consider a new TV or taking it in to a repair shop.

Are these vertical or horizontal lines?

Its not a button, you need to do a factory reset, your manual that came with the TV will tell you how to do it, its different with every make of set

Could you explain what you mean by changes colour, please?

Hello, I recommend checking with tvpartsguy as they have a ton of product and can even help you diagnose the issue.

It will depend upon users interest. Nobody can advice more.

Color issues are almost always caused by a bad TCON board

See if resetting the electronics to factory defaults cures the issue. If not, get some ear plugs till you have the main board replaced. TV Parts Universal TV Stands DLP Chips ShopJimmy
