Question about HP Televison & Video

2 Answers

Sony model 51-ws510, Picture is drawn in from top to bottom in the middle of the screen (keystone) all images are on the screen but distorted. I think it might be the high voltage block assy, but before ordering it I need a pro's view on the problem. The sound is ok. Thanks, gary johnson garydj10@gmail.com

    Tbanks, the serial number is 8733955. Should I order the service manual for the set before replacing the ic's? I have looked at the boards from the back but couldn't identify the ic's visually. As I look at the set from the back I see 3 boards, the vertical one where the power comes in, and two large boards laying flat. I do appreciate the assistance. Thanks again, Gary

No this is a convergence issue. Try auto convergence if this doesnt work. Try manual convergence. If that doesnt work then its your IC chips.

    Thanks for posting picture and it really helped to understand the tv problem.
    It is failure of convergence out ICs and if you have little experience of Tv repair and solder work, you can replace these ICs.

    And if you don't wish to do it yourself, you can replace complete board.

    I think it would be nice if you get related service manual from any online part store.
    service manual would help you to find part location, board location ect.

Sony Bravia flat screen TV when turned on has black screen. Green light on the bottom is lite up, electric plug is plugged into house socket, no picture only black screen.


If audio is OK, the fault is with its backlight section. If audio too is absent, the fault is with its digital main board. If you wish to get more details visit the site linked here. Pull up older posts.

WHY DID MY VIORE SCREEN RESIZE TO SMALLER SCREEN


Screen size depends on the broadcast signals aspect ratio, the TV adjusts for that automatically, the picture can have no bands or be banded top and bottom or on both sides.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
