2. High Voltage leak and Hissing noise from a badly soldered connection or worse no silicone end caps to protect and shield the solder joints.
3. lamp is fit inside reflector placed inside lcd and closed but not a good fit and when attempt to make layers of internal sheets sit properly the lamp will break from wrong positioning.
4. badly soldered connections spikes of solder or week connections can cause the pink wire to detach from the lamp even when lcd reassembled.
5. Bits of debris from shattered lamp inside the lcd after reassembly and test with inverter to power up the lamp shows small to large glass's plastic or dust sandwiched in the different layers of lcd most laptop LCDs have 6 layers and the Glass panel.
6. Layers of plastic film inside the lcd can melt from badly soldered connections, one diffused clear sheet 2 sheets clear plastic diffusers one dotted sheet one large perspex panel which the reflector sits on. and a white sheet of plastic reflective back
7. smudge marks on sheets from handling or touching sheets, also 2 sheets are made with hard to see lines grooved to the surface of both sheets if touched will distort the finished lcd display when powered up to windows, or will scratch.click to enlarge

It is generally better to repair
than to replace for a number of reasons. Typical CRT monitors life is 10,000 to
20,000 hours and LCD’s 20,000 to 30,000 hours. All it takes is a tiny component
to render a monitor useless. Until the tube, Fly-back high-voltage transformer or voltage inverter fails it would be wise getting the unit
repaired. Repairing would make your company ecologically friendly by reducing
the amount of computer waste in our landfills. All monitors and laptops contain
potentially dangerous heavy metals. Lastly, repairing will save you money over
buying a new monitor.

If your LCD power’s up with a red tint a orange tint or a pink tint then you will need a new Backlight fitted into the LCD panel and tested with the right electronic equipment, if it powers up flashes then goes off and blank replacing the inverter with a new one will not change the fact that the lamp is not the correct load anymore for the inverter PCB thus just because your LCD powers on then goes blank or flickers then goes off in our experience is a bad Backlight or sometimes less often is a bad inverter transformers secondary winding. The inverter is built in with a small Like controller IC sensing the lamps impedance feedback volts and load any wrong effect will simply place the inverter powering your Backlight into self protect mode or simply put will turn itself off. remember to place new end caps on the glass ends or you may get hissing or interference on the Thin film transistors that sit in each squarepixel on the surface of the glass panel.
