Question about Sony KP-53HS10 TV

1 Answer

Sony KP-53HS10 lines flicker across screen

Lines flicker across screen with any input device (SAT, DVD), similar to RF cable being loose. Power down used to fix this but no more. Also Flash Focus convergence has to be done more often

    Thanks for the help. Unfortunately the flickering went away before I did what you suggested. I went ahead and did it anyway. The upright circuit board (perpendicular to the input connectors) that you suggested to remove was very secure in the slot. I was able to rock it back and forth but the center of the board remained secure. I did not want to force it out fearing damage. I blew out all the dust around it and on all the circuit boards and secured the Comb filter. Hopefully your diagnosis worked

Tap around on the circuit boards in the rear of the television. narrowed it down to the Comb Filter circuit board. It is the smallest upright circuit board behind where you plug in all your connectors. pulled it out cleaned it off, reinserted it

I have a Sony rear projection tv model # KP 53HS10 I need to connect to a Direct TV satellite box

Depending on the way that you want to do this, you can use a short coax to connect to the antenna input and the sat box. You can use component cables to connect from the sat to the set. If you do that you need 3 cables for video and two for sound. You can use svideo also and maybe digital audio.

Sony Bravia KVL-V40A10 - pixelated lines top and bottom of screen

Are these lines visible regardless of what device (DVD player, cable box) you are watching?  If so, then yes, it appears the LCD panel is failing.  If you only see the lines watching one device, it could be the cable/wire or the device itself.  Now it can also be the related input jacks too so connect the device to another input to be sure.

Sony vega 36" tv

Hello ladybaker,

This is possibly a problem with the low voltage power supply, or it could be a problem with the tuner. To test this out. What I need for you to do is to disconnect the cable from you cable TV set top box to the RF connector of your TV. Then I want you to connect either your composite or component video cables from the set top box to the TV and using the remote switch the input from the RF (tuner) to the composite input and note if this removes those lines. The select the component video input from the menu and note if this gets rid of those lines.

If the lines disappear for the composite and component video input test. Then the problem is in the tuner, if the lines remain then the problem is in the power supply or there is a video problem.

In either case after the test I would suggest that you have a qualified TV technician troubleshoot the TV and repair the problem. At least you will have input to tell the technician on whether the problem is in the tuner or the power supply/video section.

I hope this helps,

Thank you,

Non-HD picture issues

Sounds like you may have something generating interference, such as a bad cable shield on maybe a ground connection inside your tv. You might try moving the cables while watching the screen and see if the pattern changes. Double pictures on a screen can be caused by "ghosts", which means that you're getting two signals--- one slightly behind the other. Anything oscillating generating a radio frequency may radiate into your circuits causing this strange problem. Stargazer
