Question about Proview PA40JK1A 40 in. LCD Television

1 Answer

Is it possible for just one iput to go bad? When I turn on the tv, sometimes the screen stays blue and there is a continous popping sound. I'm thinking it is only my HD input because I can still switch to HDMI input and watch a movie from my DVD player. Can I get this fixed?

Hello,
The reason you have a popping sound is because there is a component that is being bridged on a panel in the television, which could be on the HD part. This can be as a result of excess heat in the unit melting off some lead and causing it to be bridged and causing some problems.

Yes you can get it fixed and yes you can have problems on just one the HD input only.

Take care

    Thank you for the information. I should have mentioned it is intermittent, although it went from random (months ago) to often (I have to turn it on and off 4 or 5 time to get it to work). I see tuner boards on ebay, but I may just need to call a repairman to know which board it is.

    one will not be able to tell the particular panel to replace except it is assessed properly.
    So it is a good choice to have a repairman run a check on it so as to tell which board needs replacement.

    Good luck

TV picture goes out after 10 minutes of viewing with popping sound


It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.
Thanks,

47LG70 - PICTURE WENT OUT. STILL HAVE SOUND. HEARD A POPPING NOISE WHEN PICTURE WENT. TV IS ONLY 1 1/2 YEARS OLD. ANY IDEAS WHAT MAY OF HAPPENED.


I have had the same problem off and on with my 47LG70 for months. When the "popping" noise happens, the blue light in the corner stays on, so I know the tv is still on (sometimes I still have sound, sometimes I don't). Sometimes the screen goes black, but other times it is blue. If I turn the tv off then on again, it might stay on for seconds, minutes or hours. It's been very frustrating.

This seemed to happen right after I got my new Comcast box, which came with an HDMI 1.3 cable. I read somewhere online that this tv might not be compatible with that cable, so I unplugged it and am using component cables again. I just did this today, so I don't know if it will work, but so far the tv has been on for 30 minutes with no problems.

I'm pretty ignorant about HDMI compared to component cables. I imagine I will not get as good a picture with the component cables, but I am willing to sacrifice quality if I can just get the darn thing to work. Mine is also only 18 months old.

Hope this helps. If it doesn't, maybe someone else out there can help us both.

Sounds like the picture tubes are failing,common on sony. do you notice any thin horizontal lines? You mite get lucky and be able to adjust the voltages. Remove back cover and look inside to see which tubes are lighting up.The front panel below the screen will come off and behind it is a small access cover.remove it. there you will find the voltage controls (its a plastic square with 6 knobs). 2 knobs for each tube, 1 is focus the other is the voltage labeled "screen". they are marked so look closely. Green is always in the middle but sometimes they flip the controls for red and blue so pay attention to which you are controlling .slowly adjust screen voltages to see if you can get it to stay on. If you over do it those thin horizontal lines will pop up and the tv will shut off again. If you already have lines back off the voltage by turning knob to the left slowly until they diappear. If that seems to fix it but the problem but it comes back later, then the tubes are shot. good luck!

Het Big AOT-

Sounds like the screen drivers for the blue and green projection CRTs sre possibly going south, or it could possibly be the CRTs(picture tubes) themselves going bad, although it would be highly unlikely for two tubes to go south at the same time. My money would be on the control circuits (screen drivers).

The easiest way to troubleshoot this problem would be to obtain a can of circuit cooler from an electronics supply house and determine the area on the motherboard where the screen drivers reside; then turn on the set and let it heat up until the problem occurs, and then carefully spray (one at a time) the components in the screen drivers area. When you hit the faulty component (probably a chip), the problem should clear --- until that part heats up to failure point again.

Determine the part #, obtain a replacement part, replace it and hopefuly the problem will be solved.

The last time I encountered a similar problem in the real world, it turned out to be a cracked circuit board, and all of the intermittently broken circuit lands had to be bridged by resoldering over the cracked area... a tedious and time consuming process.

If the set is still covered under warranty, let Sony fix it... any attempts by you could void the warranty!

Hope this helps and good luck! Keep us posted as to your results...
