Question about Standard (CRT) Televisions

1 Answer

Toshiba TZ55V61 Hi all, My TV has shaded text appearing lately, and I have been reading about it. It sounds like I need to replace IC's. Being not a TV tech but know PCs well, will this be something like replace them by pulling out and putting new ones? Will it require soldering? just wondering if I can do this and myself or a TV tech is essential? Kindly advise. Thanks.

Re: Toshiba TZ55V61

Hi, I`m assuming your saying the letters on the screen have different colors (red, blue, or green) shifted to the left or right?
If so try going into the menu and adjusting your "convergence"
adjustments, basically, move the red onto the green then move the blue onto the green and the bar turns white, if one or more of the colors doesn`t adjust either up/down or left/right then the convergence IC`s have failed, this will require removal of the board and unsoldering the old IC`s and installing and soldering in the new IC`s, questions? e-mail me back, BMW Rider

Vertical line

Check the deflection yoke connection cable for any loose contact at its connection socket at main board side. Unplug the connector out from the socket, and re-plug it back for at least tow times. Check the solder terminals of all connections to horizontal output. It will be best to re-solder all suspected solder terminals there. [horizontal sweep signals to the deflection yoke is absent now. Only vertical sweep is present now]

My 15 year old Toshiba Televisiononly shows a narrow horizontal band in the middle of the screen. Sound OK.

Hiii fairley,

You aren't specsificly dercribe yor tv set.
For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,'s can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

If flexing the board will "fix" the problem, then the most likely issue is poor solder connections on that board. Look for any connections that appear grainy or have rings and resolder them. The IC involved here is the vertical IC which will be a small flat IC attached to a heatsink. It may be marked LA7837 or something similar and have about 9-11 pins.

Try the resoldering and update this with your results.

No picture

Just increase the screen voltage slightly by turning the screen control on the LOT and if a horizontal line appears, check the vertical IC supply, and if everything is okay, change the vertical IC, it is not costly.
