Usually with these types of TVs the fuse is located on a circuit board inside, often right next to where the power cord enters through the plastic case of the tv. If you are not familiar with electronics, I would not recommend replacing the fuse yourself, for safety reasons. See if you can get a professional to do it for you, or at least a friend that is familiar with electronic devices. Good luck! Der Strom

Try to resolder or check for cold solder on PC boards..if not, for your safety you have to consult it with electronic serviceman certified..

try search in google.com

check the H-out transistor..or the B+

Have you check the power cable connection the check the fuse

try using remote control

try hard reset unplug for hrs

Hi haydenjessa6,

Instead of toothpaste (although it will leave TV set minty fresh) go to your local glass shop. You know the place; where they replace windshields and sell windows and mirrors. They will have a powder polish that you can use and might only charge you a small fee for a small amount. You might find it at a local jeweler as well. Ask for "jewelers rouge" or "polishing rouge". Mix it one part to one part water and one part glycerin and use the polishing wheel on a roto-tool (Dremel).

Another product to try is an automotive polishing compound such as Dupont 7.

Of course all of this is assuming that this is a glass screen and not a plastic screen on a projection TV. Remember that if the scratch is too deep no amount of polishing will remove it...

Good luck,
Rob

Yes,Try website 1-800-remotes Factory original.To buy an exact remote.

Check the supply voltage for the IC sound or change the IC.

Chech the tuner

should be 1 of these codes :
0060 0579 0035 0036

hope this helps :)

PRESS DISP+VSM TOGETHER AND THE SERVICE MENU WILL OPEN.

horizontal over scan , one H.V. cap is out of tolerance in hoz deflection
Fair Cost to fix 75.00 could be a few leaky diodes to. in addition to the cap

To enter SDAM, press the following key sequence on the remote control
transmitter: 0 6 2 5 9 6 directly followed by the MENU button (do not allow
the display to time out between entries while keying the sequence).

Hello This is an indication that your vertical output stage is beginning to malfunction. It could be the vertical output IC or the vertical coupling capacitor. I would suggest using the schematic and an oscilloscope to determine if the signal is correct. You may have to replace the IC or the capacitor.

I hope this helps,

Thank you,

I have a 32 inch phillips tv that I bought from someone else and it has a child lock code on certain channels. How do I get this code off.

Your problem discription is not very detailed but certainly it sounds like the first place to look would be at the fuses if the set is completely dead. Good luck.

wepu, Buddy it sounds like you got a power supply problem. As you say the picture is all blue?? With no video or sound and the fact that the channel display is out is the first indication that i would guess this. Do you still have the owners manual that you got when you first got the set? Good, cause thats the only place i can think of where to look in case of service over in your part of the world as I did try!! Man I tryed but to no avail. No one has heard of this model but that dosent mean that it dos'ent exsit!.. If your a tech or know your way around solid state circuitry then you should have no problem finding the fault once you get a service manual from the service location in your owners manual. Now if your not a tech and a handy man ?? If I were you I wouldnt mess with the tv as theres over 25000 volts inside the set and i've seen it make a grown man cry. Man dont attempt the repair or troubleshooting if you dont have the right or proper tools and equipment!!! Good Luck
