My daughter threw a toy at the tv. The TV is not cracked but the is a splash colour on the screen. can it be fixed/


Hi, Unfortunately this is a crack internally, the spalsh of colour is the Liquid Crystals running through the cracks, the cracks can be very fine and not visible because of the spread of liquid. this can't be fixed, it would require a new screen which could be very expensive if you can get one.

you could try claiming on household insurance if it covers for things like this.

Hope this helps.

I have a 37" BENQ LCD(model # DV3750), I was watching the tv and it poped then would not turn on. I called a tech and they told me it mabe the power supply, so i took the back off the tv and looked at the...


I have the exact same part burned at the bottom. I just used a long nose plier and bend the bottom so it touches the print board circuit. It works. I guess I could also use a soldering iron to fix it. But will see if this temp solution works or not.

Blown power supply


If it's possible, install a small computer style fan and direct the air stream over the power supply. You should then get another 10 years out of it. Unit needs ventilation and cooling air. Hopefully, it isn't installed in tight quarters.

CRT TV Screen Colors Off


The tv needs degaussing (demagnetizing) unplugg the set tonight and then plug it and turn it on in the morning. You should hear a a "bonk" noise when the set is first turned on after being cold- this is the internal degausse circuit working and it should fix your problem if you don't hear the "bonk" sound or it does not fix your problem call arepair shop to have the degausse your set and possibly fix the internal degausse circuit.

When monitor dims and goes black i turn it off , hit the bottom left side (near the BENQ logo) turn it on again and it works ..

This works every time for me . But after a while it switches off again , could be 5 minutes could be 5 hours . Its random

Philips Magnavox ts3258c101:service manual for free anywhere?


I couldn't tell you where to find a free service manuel as it seems these days every ones looking for a buck for what they offer, but as for fixing it it is possible that the switching board ( the board that houses all the function switches ) is cracked. You can remove the board by removing the 1/4 inch screws and find the cracked section by visually inspecting it. With a soldering iron , solder and some bear wire, you can patch the broken board. After repairing the broken connections, apply some epoxy glue on the back of the board where the crack was and reinstall the board after the glue drys. It should work fine after the minor repair.
