Sylvania 6632LG 32 in. LCD HDTV - Answered Questions & Fixed issues

The inverter board needs replacement. You can get the inverter board at the following link www.tvrepairworld.com

you have a short, most likely on the front side of the power supply.

Sounds like a bulb.

Check power supply board and inverter board for faulty solder connections and visually inspect electrolytic capacitors for signs of stress or failure. Bulging tops, black or brown crusty material oozing out of them, are the most common. Replace those that are visibly faulty with high ripple current types. If that does not resolve it, the next step is to test the transistors in the 24 volt section and inverter section primarily. Recapping the power supply 24 volt section is prudent regardless of physical appearance of the electrolytic capacitors.

Please look at the on screen setup/sound setup.

It is your power supply, if you replace it. It will take care of your problems, The power supply is weak.

When you press the power button do any front panel lights come on? If so, turn out all lights and then turn on the tv. See if you can barely see a picture or any light in the background. LCD tv's work about the same as conventional flourescent lighting. Each light has a ballast (transformer) and when it completely charges up you have light. When the transformer starts to go bad you get flickering of the light or no light. On LCD tv's you can find capacitors on the power supply that when they charge up the back lights power on which shows the picture. If the capacitors are too weak or shot then the back lights do not come on leaving the screen dark. If this is your problem take it to a repair shop or have a technician come to your house and fix it. Hopefully this is all it is. You can also try to hold your power button in for about five to 15 seconds to see if the tv resets. How old is the tv?

If it is a CRT TV.

Plz check inside the TV mostly rectifier Diodes, Capacitor , transistor in the powersupply section would have gone short or then Flyback transformer or Flyback Transistor would have gone bad.

to test your remote get your digital camera turn it on and point the remote at the camera you should see a the remote
light up on the screen if not then you need a remote and you can get a new one on the Funai web site . that who makes your set good luck

The power supply may have gone out, that is the first place to look, look for blown fuse, burnt parts, bad capacitors.

Please post back what you find.

These flat panel tv's all have a problem with bad leaky capacitors. look for any capacitors ( round cylinder shape with a metal top) that have the top rounded over (bulged up) that part would be bad.

I too had this problem. I read some posts on this site about how to repair it, and low behold, they worked! I took the back off of the TV, and the first thing I found was the fuse was blown. With my meter, I checked the first 1N5406 rectifier diode after the fuse, and found that it had shorted out. Then I had to learn to desolder the diode, which I learned about on Youtube. I bought a pair replacement diodes at Radioshack for $1.49 and four replacement 125 volt 4 amp fuses. The whole repair cost about $5.00 and a few hours about learning about electronics. The TV works great! Good times!

on the back of your tv there will be an input marked VGA or PC input. connect your cpu(computer) to this input just like you do to your existing monitor. then use your tv remote to select pc or vga input as your source for video. mch

hi
I had the same problem but i found a solution
look all what you have to do is to hit the screen with your hand a few small hits and it will get back to normal.

there is an internal problem and that will need a tech to get into the set to repair it, most likely having to replace the board that controls the colors

are you able to get video using a dvd input??

please check if its a signal fault of video boards fault

Went to tech support for Dish

go there hit support the right the model # in the box

you can get a fire that is in .pdf format if you need the software to open it go www.adobe.com download adobe acrobat reader the hole manual can be printed or just consulted on the pc !

try a diffenrt outlet if it still bunrs of a different fuse! could be the fuse not big enough for the different appliance on the circuit !


i would suggest take it to a tech it could be a problem in the tv that could cost only a few $ to fix !!!!
against trying to much to plug it in and out you could burn transistors or other expensive part of the tv!

since the only thing you did was move the tv i would say you have a loose solder connection inside the set. you can unplug everything from the tv and unplug it from the wall for a couple of hours. see if that helps
