LG 55LW5600 problem Symptoms: no audio, no video, no backlight.


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Display not working, power button LED turns on blue for 1 second and won't turn on again


Have you tried checking with another monitor. Meaning that if the second monitor does not come on then the problem is with your computers mother board. But if the monitor other monitor you check it with comes on then of course it is your monitor.

My TV intermittently will not power on properly. Should I replace the logic board or the power supply board?


easy answer I always replace the least expensive part first. If it doesn't fix it at least you have a new part. since the logic board talks to the power board it could be either one.

The TV won't turn on. The little light by the power button doesn't even come on


Blown fuse caused by a shorted power supply. Relacing the power supply board should solve the issue in most cases. You can get a power supply board from www.tvrepairworld.com

TV will not come on even though the light turns blue


check for leak or bad capacitors in the power supply board, then if you can make a voltage checking just to ensure if output voltage in the power supply board are present. the 5v standby 5v switch 12v and 24vdc at the power supply doesn't drop.

Sumsung hps5053 would not turn on


I fixed this model of TV. Symptom was NO POWER. Totally dead. Not even a blue LED up front. Here's what I had to do...
I found a blown thermistor on the power supply board. It's green and located near the 120vac mains input to the board. There is a component number written on the board near it (as with all components) and it begins with "TH" i believe. So it will be something like "TH101". It was very easy to identify that this part had gone bad on my power supply, as i was literally blown apart and debris had been scattered all about the area.
Before finding this faulty component, I had done some preliminary voltage testing from the power supply's outputs. I started with the 5 volt stand by signal feeding into the logic controller board. It was bouncing around from 1v-3v.
After replacing the faulty thermistor, there was a steady 5v signal on the standby circuit. However, the blue power button was still not illuminating. And there was absolutely no voltage going into the power button board (which is fed from the logic controller). So after attempting to replace a few dozen suspect high ESR SMD caps on the logic board (to no avail), I ordered a new one.
And then the TV came to life.
Works great now!
Feel free to ask for advice.

My Soyo DYLT032 has power but no picture or sound


Long story short: 
Had the same problem with my Soyo. 
Thought it was the power supply board problem that everyone else was reporting. 
ordered one.  Plugged it in.  Did not work. 
Inspected the Main/Logic board and found what looked like a black button that could be depressed.  It is located to the right of main processor on the board.  You can't really miss it. 
With the TV plugged in, I pressed the suspect button.  The TV made a buzzing/clicking noise for a few moments and the stuck blue illuminated power button faded away. 
Curious by this, I pressed the power button and low and behold the TV comes to life! 
Looks like I found a "reset" button which seems to have fixed my problem. 
Thanks Soyo for not bothering to mention that such a button exists. 
I hope the rest of you have the same good luck.  In the event you are still in need of a power supply board, email me.  I have a spare now it seems.  ;)
