Having problems with your Flat Panel Televisions ?

My television is two and a half years old, and therefore outside of the warranty period. All of my HDMI inputs have stopped working, but the other video and audio inputs work fine. I have tried disconnecting the power supply and restarting, but they still do not work. Any advice on what could be wrong and how to fix it? I'm not afraid to work on the unit myself, but would also be interested to find out how much it might cost to fix.

  1. Try using a new HDMI cable, unless you have verified that your current HDMI cable works on another television.

  3. If this does not fix your problem, I would recommend taking the television to a TV Repair Shop. It is possible that the HDMI inputs have worn out, or the input control board may be at fault.

I have a Sharp Aquos 40E67UN. We came home yesterday and although the TV turns on and our directv box turns on, the tv just has a blank screen where you can go to different inputs, but none of the hdmi inputs work. I also tried hooking in my DVD player via 2 different hdmi cords to make sure that it was the direct tv box that was the issue, but the DVD wouldn't work either....just a blank tv screen (but its on). Any ideas on what could be wrong? I can change the channels, the remote is still

Sylvania LC260SC8 LCD TV has no picture. It displays white & black vertical lines on the middle to left had side of the TV. Audio still works fine. I swapped out HDMI cables, tried using the component inputs, hooked the co-ax to the TV instead of the cable box, tried 2 different video inputs all with the same issue - no picture, only audio works. Is there something that can be done to fix the TV? I love this TV. It's only 3 years old. Thanks for the help.

For some time now, my Samsung DLp rear projetion tv (HL-R4667W) gives a "no signal or weak signal" on all inputs. After being on for a perdiod of time, which seems to be lengthening, it will pick up the HDMI input. It still is hit or miss with other inputs, such as Component or RCA. I don't know much about the inner workings of TVs, but am assuming this is some type of input board issue or something. What is the problem and what kind of part would fix it? thanks.


Yes it is a board malfunction. The source of the problem in your case is the "Digital Board" which contains all the tuners and video processing circuits. Replacing it would resolve the problem. If you would like to fix it yourself, take off the back ... Samsung Flat Panel Televisions

INTERMITTANT failure of the I/R sensor? sometimes remote will work properly, othertimes remote will not work nor will manuel chanel up/down on/off buttons on set itself. i had a service agreement and brought it to the only service in my state, 90 min drive each way, they could not find a problem, as soon as i plugged it in it failed to work, now service contract has expired. still continues to be an intermittant problem. What parts might i consider replacing?


I don't think it's the remote nor the I/R sensor that's bad. It might be a processor problem on the control board - need to troubleshoot further. Since it is intermittent, I believe it's a cold solder connection on the board. You can inspect the boar ... Venturer PLV31220S1 22 in. LCD TV

I have a Blaupunkt IS 70-33VT PIP TV. It has worked perfectly since 1994 and the picture and channell changing are still good, but the sound only works when the volume control is being increased. The local tech says parts for older sets are impossible to obtain and they are not worth the effort. I would really like to prove him wrong and believe I have enough ability to replace a component if I can discover which one. Any advice you can give will be greatly appreciated.
