Just hold the power button and press the eject button might take a few times but it will reset the television and correct the multiple screen colors

Sounds like the main board causing that type of symptom. You can get replacement main boards from www.tvrepairworld.com

SOURCE: Emerson flat screen tv with red stripe

The pixels on your screen are controlled by a matrix composed of switches that turn off and on to produce light.

They are located vertically and horizontally, row-wise and must function together to produce everything from black (everything turned on so no light, or very little, can escape) to layers that represent the three colors that are used alone or in combination to produce the millions of possible shades of each.

One of the switches that controls one of the vertical columns has failed and has turned on the entire column that allows red to display.

The problem switch (a semiconductor combined with many) is permanently turned on, probably part of the screen assembly itself, and was placed with others by robots.
The pin spacing on these 'chips' is very small and often makes the assembly unrepairable.

While LCD panels have fallen hugely in price, you may be looking at a parts cost (labor is probably not too bad) that may make you decide to replace the set.

Unfortunately, the once-proud Emerson name has sadly been degraded and there is a lot of their electronics available from companies that specialize in 'refurbished' products, an indication that they have a large failure rate.

SOURCE: I have an emerson flat screen that will not turn on ? The red stand by light comes on, but when you hit the power button the green light comes on then shuts off quickly and the TV will not come on?? A

Try leaving the TV unplugged for 30 mins so the TV can reset itself.
If that doesn't work, most cases with the Emerson TV, the Inverter Transformer goes bad on the backlight Inverter Board. It's what powers the screen for your TV. If it can't power up the screen, it automatically shuts off. Basically, they call this "Protection Mode" with this happens.

You can get a replacement backlight inverter board at this web site link:

Just make sure the board number matches your board.

If it fixes the problem and you decide to throw your old board in the trash, I would like to keep the damaged board if possible. I want to do some research on the board to find out what really causes the transformers to go bad. Here's my e-mail dsacco86@hotmail.com

SOURCE: LG 26LG30 screen suddently went blank. Light flashing blue/red

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

I have a Emerson 32inch LHD32K20US and it won't


ry changing the input device to something you are sure, works such as a DVD player. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

I fell asleep on my Emerson LC320EMX 32 hdtv remote; when I awoke, the tv was flashing ONLY colors (red, black,blue,white)...Now, How do I get it out of that mode....I was told its stuck in set-mode ?


I had this problem with the LC320EMX, after extensive searching on the internet, I found a solution. The TV has entered some kind of test pattern, to escape from the flashing color test pattern do the following:
While the screen is changing from red,green,Blue,White, & Black, and is Unresposive, Take your factory remote, Press the up arrow, then the down arrow, then (ON THE TV) press the power button. Turn the set back on and it should be functioning properly. (BTW: the set gets into this test pattern if you press too many buttons on the remote, or if you use a universal remote with the wrong code)
