Digihome tv has sound but no picture only coloured vertical lines

SOURCE: TLM 2619 MODEL-DISPLAY PROBLEM

Hi,

Hi,


The most common cause for the loss of picture is a bad Horizontal Output Transistor (HOT). but I would suggest you get a detailed estimate. I think that this would cost you about $60.

The horizontal lines means the vertical amplifier or deflection system has failed. There are over 100 components in this section and any one of them, or most of them can be at fault. However, the most common failure is the VOT or vertical output transistor (which is often buried inside a chip).

The repair will cost around $250 plus or minus.

FEW TROUBLESHOOTING STEPS YOU CAN TRY:

ONE: Do a hard reset (just to make sure there is nothing in the coding that is fowling things up). Unplug the power cord; leave it disconnected for 4 hours. That will restore everything to factory defaults when you power it back up.

TWO: Do the "whacking test" by banging your fist on a few strategic places to see if there are any cold solder joints or loose wires acting up inside the set.

If the above steps don't solve ur problem then I suggest you to go for a repair..

Goodluck..

SOURCE: Vertical colour lines on whole screen

The problem is that the panel has failed. Apparently this is a common problem with LCD TV's between 18 mths and 3 yrs old. If it survives over 3 yrs it is likely to last for a few years longer. The cost of replacing the panel is more than a replacement TV!

SOURCE: I have coloured vertical lines covering my Sony

I also have a 2 yr old Sony KDL32xbr4 that now has multi-colored vertical lines on the screen. I contacted Sony and they say they have "no known issue" of this sort for this model. I find this rather puzzling since I have found numerous postings on the web. They told me to try the factory reset. Whatever. Might as well have said "don't buy a Sony". 2 years! $1300 for a tv and it lasts 2 years! Makes me sick to my stomach.
