Having problems with your Flat Panel Televisions ?

Answers :

That's a clear indication that you have a bad power supply in your TV.
If\012 you know how to DiY...I suggest you open your TV. Locate the power \012supply section, it is where the end of the power plug is connected. \012Replace all blown or bulge or leaked capacitors with same value. That \012will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board

After replacing blown capacitors...it should work again.

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Hope it helps

So I went to play a dvd by removing the HDMI from the back of the HD cable box and plugging it into my DVD player, then returned it back to the cable box when done. Then the volume would not work on the TV, a plug symbol appeared in place of the speaker symbol ...but the lines and numbers appeared for the level of volume. What am I needing to do for the volume to return?

Try to unplug the box for a while and then power it backup and let it reboot---never remove a HDMI connection with set/box on.You can if that fails call the cable company and have them reboot the box over the line. ... Sharp Aquos LC-45GD4U 45 in. LCD HDTV

Sanyo dp50747 TV turned itself on and will not turn on. The green power light located on the front panel lights up and the side panel off/on works but no sound or picture is shown. The front panel green light stays lit. The TV did this again about one month ago but I just turned it back on. Yesterday, it turned itself on and now does not turn on with the sound or picture shown.

When making an initial set up for motorola set box VIP 1003, the red light comes on, 3rd on the screen and the whole set up process begins over. Blinking yellow light circle turnes green and after the first two get green the third becomes red. Does it mean that the hardware has a fault, or there's something in "system function" menu that can be adjusted to resolve the halt on the software downloading for my set box?

My Olevia LT26HVX has suddenly lost color control. It has been set with color temperature on Middle for all the time I have used the set. Yesterday when I turned the unit on, the picture is hot pink or magenta with little blue and no green. If I set the temperature to Cool, the color switches to mostly lime green with solid blue areas appearing as black. If I set the temperature to Warm, the screen picks up more blue but has an overall muted green cast with no red. If I select "user" for color

I have a Verizon (Frontier) FIOS set top box model HD QIP 7100 1 and an LG TV model 42LD520. The power button on the remote control for the set top box does not turn off the set top box AND the TV simultaneously. The circumvention is to press the TV button and then the power button to turn the TV off separately. I'm thinking that the code for the TV is not programmed into the remote correctly. I've tried 1292, 0205, 0727, 0883, and 1205.

I have a Mitsubishi WD-73737 and when I turn on the tv the power light flashes very fast for a minute then stays a steady green and the screen is a solid blue. There is no sound as well. I have tried the system reset and it didn't do anything. I was given this tv, so I don't know how old it is. The tv will occasionally work but that is very random. The only item I have plugged in is an Xbox 360 with the component cables. The menu button does work so I know the screen still works.

Do you have the input turned on that you use the xbox for? Try different inputs as well. If you are getting the menu to come up, the blue screen is telling you that you don't have a signal being run through that particular input. ... Projection Televisions

I have a panasonic TH-C42HD18. Last night a fuse in my fuse box flipped so I lost power to the tv. I reset the fuse (in the fuse box) but now My tv will not turn on. Everything else plugged in to that outlet is working (ie: dtv, blueray) but no power at all when it comes to my tv. Is there a reset or something maybe?

I have an LG 26LZ5RV TV. I have connected it from the RF output of my Sky+ box (using a coaxial cable) to the "Ant In" socket at the back of the TV. The RF output on the Sky box is set to Channel 35 and the power is on. I know that the output is working, as I have tested it on an old portable TV with manual tuning. My problem is that I cannot get my LG TV to tune in to the signal, using either auto or manual tuning. I have used System "I" and tried setting the Channel to 35 then searching b

My wt-46809 Still has a good picture. It receives its signal from an HD converter box from Time Warner Cable. The other inputs on the tv however don't seem to work. I can't use my DVD or hook up any game systems through the various inputs. In addition, while the HD channels (1000 and up) work, channels 1-999 don't project a picture (only audio). I've never added any HD retrofit to the set, so I'm not sure if true HD is being projected or if the picture is just very good digitally clear SD.
