Question about Konka Televison & Video

1 Answer

My 37" 720p TV was purchased at Zellers in summer/fall 2008. I have lost all video feed, however my audio is intact. The screen displays nothing other than illumination. I have tried various remote control options however I still have no video. All cables and cords have been reviewed, replugged, timed out etc. What do you suggest?

The tv has a video fault. If the whole image is still visible if you shoot a torch in it then the CCFL tubes (or their inverter board) that provide the back lighting have failed . If the menu is still visible then the fault is in the image processor. If the image is completely gone then the mainboard is defective.
The only way to know for sure is to open the tv and test the components. A good knowledge of electronics is mandatory, if you don't have it then call a repairman or take the tv to a shop.

I lost picture and Audio,I just replaced the Y sustain board and still doesn't work, what else should I do?


If you get a blue screen when it's on, try feeding in an external audio and video source, like a camcorder or VCR, and see if it displays. Check setup or input selection. If it's set to video or HDMI source and nothing is plugged in, you'd get a blue screen.

I cant get it to work on full screen


I am having this same problem as this one above (62HM95). The issue I'm having is that it will also not work full screen. I selected the 'Split' option on the remote and the picture on the left is fine... absolutely clean and perfect, with audio. The picture on the right is completely distorted in very strange colors (mostly constant variations of purple), with audio as well. You should note, that the same video information was feed into different imputes to select for the split. In other words, I feed the cable stream into the TV using the component video (Y B R) as well as the coaxial cable and selected both options for the purposes of displaying the same information side-by-side. On screen I selected video option four (4 for color stream HD) and option (0 for cable/antenna). If I highlight either side and select one of them (4 or 0) the screen goes full screen and I see nothing but one solid color of purple. I've researched the purple and they call it 'Electric Purple'. That is all I see... just the solid purple, with the audio. What I have also noticed is that, If toggle between imputes while in the full screen option and come back to either option (4 or 0) the image plays/appears OK for about 2 seconds then goes back to solid purple. I just can't understand why this is happening especially when the on-screen menu displays perfectly fine. I cannot enjoy this TV by only watching half of it in split mode. Besides the multiple replacement bulbs I've had to buy I've completely had it with this TV

Toshiba V231 UK VHS manual is lost. Since last week I disconected and then replaced to my Toshiba TV. I can not Autotune it back to play VHS recvordings. I get sound but the tracking just flickers up the...


Hello,

I believe you are using a RF wire Connecting a VHS, then searching TV station is an old way. I would recommend you use a RCA wire. By so doing, you won't need to tune any station on your TV. All you need to is select Source (AV) on the TV and the VHS would automatically display on your TV.

Below is what the RCA cord looks like:

walesarumi_111.jpg

The yellow stands for video (display), while the red and white stands for audio left and right (sound).

Purchase this cord from any electronics part store within your area, it's not expensive at all.

Look at the back of your TV, connect the yellow cord to "Video IN", connect the red and white to "Audio IN". Then connect the other end of the cord to Yellow: "Video OUT", and red or white to "Audio OUT", at the back of the VHS.

After the above connection, turn on the VHS, insert a tape, and press play. While the VHS is play, turn on the TV, select Source (AV) on your TV and your VHS will start displaying and you will hear sound.

I hope the above is clear. If you need further assistance, please let me know.

Regards.

Try using the Audio line out RCA jacks feeding a PC powered speakers to see if it does the same thing, If it is OK, then the problem will be in the power amp sections that drive the speakers.

When the tv is turned on the sound comes on but no video feed, not even the on screen displays.


you have to make sure you are on the same inputs for video and audio. for example if you are on video 1 but audio 2 and your monitor is set to video 2, you will only get sound.

I recently purchased an xbox, but because of the cable box, i dont know to to get video


Your cable box and TV should have RCA input jacks (Red, White, and Yellow) Red & White are for Audio and Yellow is for video feed...

HD Receivers & HD TV's are just slightly more upgraded with better video feed connections.
HD video can use three color coded RCA jacks for the video feed or a HDMI cable; if you can use the HDMI connection on your TV I recommend using that because it's less confusing to plugin the input cables. Try turning your TV to it's side to see what inputs you have available to connect your device to.

After you have it pugged your device into the input jacks press the "Input" key on your TV remote and power up the device.
Most TV's have more than one input, so you may have to cycle through the TV inputs by press the input key again until the video feed is displayed.
(If you don't have a "input" button on the TV or remote control you can try entering channel "00")

Receiver lcd display doesnot work


Does the 605 have the "pure audio" setting (my 705 does)? If that is selected, it cuts out the lcd display on the front.

Lost audio & video


You say that you lost audio and video but the screen is blue. That indicates that the majority of the circuits are working OK. To display anything on the screen the high voltage and drive circuits would be working ok. Try an input other than cable (the tuner input) and see what happens. If your unit works through those inputs then you have a bad tuner or matrix IC. If that doesn't give you any results then you probably have a microprocessor issue. The bad news is that Apex does not support their equipment so if the problem is not simple it will probably not be reparable. Good luck.
