SOURCE: Black Vertical line about an inch wide right of middle - PFM-42V1 Sony

The problem is the actual PDP panel address chips blown or a faulty ribbon cable to the PDP or if your lucky it may be a dry joint - Tap the ribbon while the set is on very lightly on all cables with something plastic and see if the black line goes away - if so your lucky and its an easy but fiddly repair.

SOURCE: Multi colored vertical lines

Probably you need an optical block, but it would take a tech looking at it to be sure

SOURCE: A fine green vertical line displayed on the Sony Bravia 46.

Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

Central Air Conditioning


It sounds like a restriction in your ducting. Feel the A/C vents in the hot rooms to see if cold air is blowing out of them. If the ducts are restricted, then it is possible that the air conditioning coils are freezing up from lack of circulation. Inspect the ducts if you can to see if there is any restriction.

Note that even if you feel air coming out of the ducts, it could be ambient as opposed to cold. The best thing is to measure the air temperature coming out of the ducts. It should be around 20 degrees colder than the ambient air at the intake of the A/C.
