SOURCE: vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

SOURCE: When I turned the tv on only vertical lines appeared

I talked to a Samsung support helpline and it needs to be taken to a service center for repair.

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00

Won't power on


my d52w19 chassis itc222 as posted most of the time wont turn on and the green light flashes three times every time it makes a small noise. sometimes it does turn on and you hear a little pop and the tv fires up.  latley there is a really high pitch noise that will slightly change pitch if you move the tv or put slight pressure on the top or botttom rear part of the chassis. thanks for the help as I have seen that this has been posted before without mention of the high pitch noise.

Won't Turn on anymore.


The high pitched squeal you refer to comes from a faulty component called a capacitor ... these store power in a circuit to compensate for AC or alternating current, thus allowing an appliance to operate continuously.

The component itself is relatively inexpensive, and would take around 20-40 minutes to isolate and replace, hence it would be relatively cheap to fix.

Having a repairman take a look and explaining the noise as above, would help narrow down the complaint.

The display is faint because of the lack of constant power getting to the display.

Black screen, high pitched squeal


A set that has only a 1/2 inch bright line through the middle of the picture, from left to right, has a vertical output IC that is not working correctly. If the 1/2 inch line is in the middle but going up and down, then the horizontal yoke circuit has stopped working. These are problems which should be looked at by a qualified tech, but if the set was purchased 6 months ago then it should still be under the manufacturer's warranty.
