Question about Televison & Video
I have two TVs both started showing a thin compressed picture in a horizontal line across the screen. I have used different cable outlets, disconnected all my other equipment but the problem persists. My smaller (and older) Sanyo will occasionally work for brief periods but there is nothing consistent going on. Cable guys came out and said it is electrical interference...what now?
If you have intermittent line horizontally across both tv screens then there is likely to be bad solder connections on the vertical ic's of both of them. This can be fixed by taking the back off with quarter inch nut driver and carefully sliding the chassis out and turning it up to see the solder side. I don't know the location numbers but the vertical ic will be mounted on a metal heat sink and the connections will be in a row. Sometimes you can see the bad connections. You may need a magnifying glass. I recommend someone who has experience soldering electronic circuits. No solder bridges etc. This is for intermittent (works sometimes) problem on vertical ic. If the line stays then the chip ic is bad along with a 1 ohm resistor off the flyback high voltage transformer. From what you described you likely have bad connections. Hope this helps
