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: Why does my tv turn off by it's self after a few

Either a power board problem or something in the set is pulling the power voltages down---if under 26 inches it may not be fixable.

SOURCE: my emerson tv won't turn on

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.6_2_2012_12_46_56_am.jpg6_2_2012_12_47_12_am.jpg

Calm down, Calm down! Your power supply board is at fault. On the power supply, you have a bad diode. Location of this diode is D639. Replace it with an NTE 5087A. Thanks for asking, Matt of Martins TV Repair.

Not making it on or out of standby---first place to look is the power supply for signs of damage or puffed up filter caps there.

Parts for this brand are hard to get---if total dead set needs to be opened and fuse and voltages checked by someone who knows how to do that at least.

If the screen is damaged/shattered you are done. Not worth the cost of the part or labor.

If something else use the "make a comment button" on this page to let me know.
