I have a Panasonic TH-42PX25 that was running fine. Turned it off the other night, next day I powered on but no picture. It seems like there is a very faint glow to the screen, but no picture. Just a solid red light on the front. I left it unplugged for a couple of days, but still the same. Any ideas?

SOURCE: LG 32LH30 screen won't power up. Red light at bottom glows hi to low, but no picture. Unplugged and waited overnight, plugged in again, still no picture.

There is a way to tell if you have a bad board, or a bad panel.

1. Make the room dark and turn on the TV. Can you see it light up? If so, does it stay lit or turn right back off?

2. If the panel lights, but you have no picture, I would suspect the T-con. Some units now have the T-con incorporated with the main board, so you will need to check.

3. If you never get any light at all, then I would suspect the power supply.

4. If you only get light for a second or two, then you have a bad panel.

SOURCE: samsung lcd tv ltm1755b won't turn on (power light stays red)

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it on.

Solution: I just had one of these come in. I opened it up, and found the U501 capacitor a little suspicious looking, in that it had a deformed top. It was a 470uF 16V electrolytic 105degC 10mm x 12mm. I replaced it with a very good quality 1000uF 16V electrolytic 105degC 10mm x 16mm Nichicon UHN1C102MPD. After that repair, when I tried to turn it on, the LED was yellow for a second, then green, then I got a picture, and it appeared to work great. I then asked the owner a week later how it was working, and they said it was working just like new!

SOURCE: TV worked fine one night, next day screen is white.

The LCD Panel failed. There is no easy fix but try to get the T-Con board to fix the issue. However, this part is usually only available with the whole LCD Panel. This is usually the most expensive part in the TV and the whole TV needs to be taken apart to replace the panel.

Might be economically viable if you can find a place that carrys the T-con but Dynex parts are usually hard to find. The LCD Panel part alone will exceed the cost of the TV.

SOURCE: power light blinks red - tv will not come on

I bought one of these tv's at a thrift store and it had the same problem, orange light blinking and static sound coming out of the speakers, no video at all.
The problem was the power supply board, this power supply has multiple outputs that feed the circuitry, 12V, 24v, 5V.
There was nine electrolitic capacitors I had to replace to fix it, all of them were bulged they are easy to spot, I measure one of them that was supposed to measure 1000uF but measured only 65uF. you can buy these from digikey for about 50 cents each, they need to be rated at 105 deg c and the profile has to be below the heat sink otherwise they will hit the top of the heat sink, the spacing between the leads has to be 5mm so they fit in the pcb. I replaced 3 1000uF/25v, 3 470uF/16v and 3 1000uF/16v and that fixed the problem, I bought this tv broken for 100 bucks fixed it with 6 bucks.
Good luck, don't perform repair if you are not familiar with dangerous AC voltage inside the TV.

Picture and Sound flash from 'on' to a black screen


Hi, The problem lies within the unit. You have a hardware failure within the board. The power supply board needs to be repaired or replaced. If you are a handy person, you can easily swap the power supply board.. If not, bring it you to local reapir shop, they will find the parts and replace it for you. I wish I had a better solution like an easy fix for you. Sorry, but on hardware failure, there is no easy fix. Thanks, Mike
