Question about Televison & Video
I took my Zenith tv in for repair last week. It smelled like burning plastic. It turns out I needed the transformer replaced and some caps replaced. I got it back and it works ok except I noticed the blacks aren't as strong and deep as they were before. What could be the problem? I checked all my connections and they were fine.
The tech did not reset the contrast

Testimonial: "Thanks for the reply. My tech guy is on vacation but I will bring this up to him. But now I have another problem with this tv: I noticed that the framing is a little off now. For example: you know how when you watch a tv and the stations logo is on the bottom right of the screen? CBS, ABC, MTV, whatever? Well, now this logo is cut off on my tv, I can only see about half of it. Also, when I watch a tv show or dvd in the widescreen format I noticed that the black bars at the bottom of the screen are slightly LARGER than the black bars at the TOP of the screen (if that makes sense). This suggests framing issues. Does my repair guy need to tweek something inside my tv?"

It definitely does not seem to be a problem with the Picture Tube. More like a cold solder. It is definitley not a job for a layman. Also, get a good technician to have a look, as locating cold solders is a labourous and time consuming process. It could also be possible that the main DC filter capacitor is getting dry, and may require replacement.

Im sorry to tell you my freind, these sets are so common for the tubes to cause this problem.. The repair guy should have told you that they shot the tube and there is no warranty on a repair such as this.. Do yourseld your wife and your wallet a favor. get rid of this set as they will string you along so far till you get fed up. Again no disrespect intended at all. Just some freindly insite. Good Luck Please do not forget to rate this thread.

After reading other postings, we figured out that it was the caption box, went to menu and turned it off.
Thanks for the great site, we wouldn't have figured it out without it !

Well that pop had something to do with the power components inside the TV frying. I would have to say there is nothing you can do to repair it as its dangerous to work on such things.
I wouln't waste my time bringing it to a repair shop they will probably tell you to just buy a new one.

SOURCE: My picture tube displays all
A thin horizontal line across the screen denote that the vertical swep or output has damaged, or there are some loose solder points to vertical output section. Loose solder problems are very common to the vertical output sections of most of the picture tube based TVs. Just open your Tv, and pull out the main baord out of it, which has the vertical output section circuit. You must have some knoldge in electronics to proceed. Locate the vertical output section. usually, this section will be composed of an IC, which will be screwed on to a metal heatslink, to radiate heat out of it when it works. Check whether there is any loose solder terminals at this section, especially look for it at the solder terminals of IC and other components around it.
It is very difficult to detect the loose solder points, as some of them may be so microscopic to detect. Just do, what we do at service table, with this type of fault comes to us. Just resolder most of the suspected solder terminals by applying a little more solder without making any sokder bridge short between adjecent solder terminals.
If this does not help you, check the input voltage to the vertical IC. If found OK, replace the vertical output IC. If there is no voltage to this IC, check the track that brings voltage to that IC. Usually, this voltage will come from one amoung the terminals of LOT [Line Output Transformer]. Check the track, rectifier diode, limiting resistor etc. This is really a skilled work, and you should have all tools for an electronic work, and a skill to detect the faulty component. OK
