    It is quite likely that the main board has sustained damage. Did the power supply have any visual damage?

    No noticeable damage, no blown capacitors , etc. do you think it's worth replacing the main board for $60-70 or just scrap?

Being that it is a Dynex, an off brand, i would toss the TV on craigslist and if you get $40 for it take the money and run. The general rule of thumb is that if you can repair the TV for less than half of the cost of a new set, you repair. If the repair cost is more than half of the cost a new set, you replace. But you also have to factor in the age of the set, brand, and whether or not it has sentimental value.

SOURCE: Dynex 37" LCD TV bad color

You have a bad LCD control board going bad,Color getting floresent? Or pixely? esp. when you have it on for a bit. Common prop. But finding parts is a prob.
They are no longer in buis. Try Shop Jimmy,or even Ebay. Encompass does not have any. Runs about 40-60.

SOURCE: My dynex tv will not come on seems to be stuck in standby mode.

It sounds like the main power supply is trying to startup but failed because there is short circuits or the main power supply is bad. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

LG DU37LZ30 Dead, Blinking red/green LEDs


most likely it is the power supply circuit board. all electronics must take in alternating current from the wall, and convert to a number of direct current voltages, before the unit can work the tuner, the picture, and so on. it is the first thing that the wall current hits. you need to find a replacement board. it is similar to the power supply of a computer. you cannot fix these boards. check cost availability. the 300 volts, or so that start up the illuminator lamp is dangerous!! assembly will be complicated, and take patience. likely, a power surge caused the problem, next time, use a spike protecting power strip, and make sure that the outlet is properly grounded, or these do not work at all.

The blinking light on the front indicates a shorted part in the power supply. The power board will need to be replace or repair to restore the LCD functionality.
