Why has my sanyo flat screen television only got coloured horizontal lines across the screen?


That might be an issue with the TVs picture tube if it was not one of the LED or LCD TVs. Please get a technician changed it. If it was any one of the LCD or LED TVs, then it would be more expensive than you expect.

I have a calumet watch, and the band is getting dirty. Is there a way to clean the band?


Polyurethane Band
Polyurethane Bands, which are made of soft plastic, may turn hard after 2-3 year's use. Colour fading can also be seen.
If bands are kept wet and in highly humid locations or are exposed to sunlight for a long time, the deterioration of the bands may be accelerated in a relatively short period and some cracks may appear on the band surface. (This is called 'hydrolytic cleavage of polyurethane')
Kindly pay attention to the condition of polyurethane bands, which are often worn in such occasions as marine sports/outdoor activities
  • We recommend immediate exchange when your polyurethane band loses elasticity or develops cracks.
  • Semi-transparent/white/fair coloured polyurethane band may turn a different colour due to light/stain ( or sometimes may absorb colours from other materials). In addition, polyurethane bands have many small holes on the surface, which easily catch and hold stains/other different colour material. Thus it is rather tough to entirely clean polyurethane bands. Kindly replace current polyurethane band with a new one when you find extreme discolouration.
  • There exist some sorts of stains (like oil/cosmetics), which cannot be removed off. Smoking cigarette/long time use may turn the colour yellowish.

CAUTION!
Do not use solvent/chemicals (benzene/thinner/breach) for band/bracelet cleaning!

Signal degradation across vertical section of


This appears to be a common complaint on LCD monitors. Some LCD screens have control issues.
An LCD screen is the panel and a bunch of Line control chips wrapped around the outer edge. A problem with one line top to bottom or left to right is almost ALWAYS the LCD panel itself.
A problem with a fixed band (The band is in the same place at any resolution) is often the LCD but might be the signal driver chip (A large plastic pack with about 100+ leads). A person with a VERY small soldering iron might be able to resolder it, but they MUST know what they are doing. (board must be heated, lead free solder, eye like an eagle...)
If the band moves around or changes width, it is the signal chip or the power supply to it from the power board.
It can be software if there is a firmware upgrade. This takes a shop.

LCD monitor have Vertical lines and black colour become greenish


normally the 19" resolution can support up to 1280*1024, but if it comes with vertical lines in full screen, it might indicate the panel is no longer to work and probably it's time to replace new one.

Black colour displaying become greenish and narrow vertical lines


Most LCD monitors have a default refresh rate of 60 Hz. Older monitors also have limited resolution. Please check your display settings and ensure you're not using a refresh rate higher than 60, or a resolution higher than what it supports. If either one is the case, you're lucky the LCD still works.

Dark horizontal bands appear on projection


Your matrix is failing. If the unit is under warranty, send it back.

The matrix is the bit that allows light to come through of each colour. If its failing one colour won't get through. If the circuitry is failing, more than one colour wont get through.
