Question about Sanyo DS31520 31" TV
I've had this tv for about 7 years and just today the screen just had a white line in the middle of it. How could I fix it?
This is a fault in the vertical circuit. It can be either a bad solder connection of the vertical IC or a defective IC. If you can solder, you can fix this yourself. Open up the back and locate teh vertical IC. It willbe a small flat IC attached to a heat sink and be marked LA7841. Resolder the pins first. If that fails to resolve the problem, replace the IC. Please note that there may be capacitors in the circuit that need to be changes as well, but without the chip working, it will be difficult to determine which ones. Update this once the IC has been resoldered or replaced with the results and we'll continue if necessary.
