Question about Samsung LA22A450 22 in. LCD TV

Open Question

Getting intermittent gray fuzz/horizontal black/white stripes

I have an old Samsung (about 12 years) that intermittently goes to either gray fuzz or horizontal black & white stripes with a static noise. This occurs when either the DVD player or the cable box is plugged in (I have a coax converter for the DVD player.)

Sometimes if I monkey with the cable, I can get the picture back for a few minutes. But even if it's tightly screwed in, it doesn't keep the picture for more than 5 minutes or so.

Since it's happening with both cable TV and DVD, I am assuming that there is something either wrong with the coaxial plug on the TV set or with a connection from the coaxial to another component within the set. The other possible contributor is that my two-year-old has been randomly pressing buttons and changed the settings. However, at a glance, the settings seem to be OK. (I lost the instruction booklet years ago.)

Thanks! About 2 days now, I'm experiencing horizontal white stripes and some colours going to gray fuzz. Some shapes are still drawn properly, but the shaded part of the image are filled with matrix-like image..
The tv is less than 1 year old, and I am assuming that it is caused by the coaxial cable or the coaxial plug on the tv, as I tested another one with the same result..
If it continues I will probably see the dealer for a support or an exchange.

You need to check the back light is still on when the screen is blank (check through the back).

If the back light is on, need to change the Powwer Board.
but,
no back light, need to change the inverter.

SOURCE: lcd tv hookup

Ive got 3 samsung tv's (lcd, plasma, DLP) and I use HDMI cables on all of them. Its the only way to get the full potential out of the tv. When you use the red/white/yellow RCA cables the signal is anolog aka "old technology". Component cables are good but HDMI is the best. HDMI is a digital signal and thats what all the components that go with the tv should be run on. If your dvd player does not have an HDMI output I would suggest getting one that has that output. As for the cable box most require you to upgrade to digital cable in order to get one with an HDMI output. If you dont want to spend the money on new components and run what you have now the picture will stay mediocre at best. Good luck hope this helped

SOURCE: 5-year old 32 in. Samsung which only displays a fuzzy gray image

It sounds like the T-CON board problem, you can try reseating the connector first, the board is mounted under the metal shield which sometime can be difficult to get to.
If you are going to DIY and have proper tools and know safety precaution then please read on:

Note:
using an optional snap on wire harness adapter will simplify the wiring. Most snap on
wire harness adapters have already converted and color coded the wires from the auto
makers in dash wire harness to match typical aftermarket radio wire colors.
** The wire colors listed in the chart above are typical for these vehicles during these years
but may not be the exact colors for this vehicle. This is another reason to use a snap on
wire harness adapter. **

Grey cable in dash


Hi again,

Appreciate the update and additional information. If I understand it right, your vehicle then has two connectors at the back: 1 big black/red/gray plug:
  • Yellow/light Green - always ON B+12;
  • Yellow/Black stripe - ACC B+12 goes to the IGN switch;
  • Black - chassis/ground;
  • Blue - remote trigger for add-on amplifier (if connected);
  • Blue/Red stripe - illumination (can go to parklight switch).
and the 2nd smaller gray 8pin plug:
  • White/Red Stripe Right Front +
  • Brown right front -
  • Green Left Front +
  • White/Orange Stripe Left Front -
  • Light Blue/Black Stripe Left Rear +
  • Yellow Left Rear -
  • White/Blue Stripe Right Rear +
  • Light Blue Right Rear -
Cheers.
