Check state of capacitors related to the ABL circuitry starting from those located close to the flyback transformer. Also check for resistor out of range in the same area.

My television has no video, only audio. It has been sitting there untouched for 3-4 months because we can't use it. Any suggestions on why this happened?


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Screen is incredibly dark, as if it was burned; cannot adjust color, tint, brightness, etc. When we bought the tv, it had a beautiful color, but now...


The LCD back light has blown, to buy a replacement you will have to visit the naxa site and see if they do spare parts, or can give you a contact number for repairs. Because it is a small lcd changing the back light might be tricky, it might be worth taking it to a repair store to see how much it would cost for the repair.
I hope this helps a bit, sorry i cant give any more info on how to get a replacment part.

The picture tends to get really dark during dark scenes. Can hardly see faces or details. Goes back to normal during brighter scenes.


the only thing you can do is adjust your brightness, contrast, sharpness controls. every station is different especially the sound is louder on some channels and lower on some.

Need adator for DTV converter box.


The converter box needs an antenna, but not the one built into the TV. In fact, you should get an antenna designed for the new DTV broadcasts to get the best reception. There are a number of styles and they start at under $10.

To connect the converter box to the TV, you have a couple of options. You can use the channel 3 or 4 output from the box and connect the cable to the TV external antenna jack with the appropriate adapter. Or, since this TV also works as a monitor, you could use the converter box video and audio outputs instead. If the TV has a single A/V input jack instead of separate audio and video jacks (the usual case), Radio Shack and other vendors sell the adapter cable you'll need. One might have been supplied with the TV.

POP and noothiing


yes it can still be fixed! the pop sound you've heard maybe came from a blown capacitor in the vertical deflection circuits. this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
