Sounds like a bad panel, horizontal lines are almost never caused by a bad tcon

Have you chanced the regulator IC?

The BG-1S chassis has a BNC video input socket and a high impedance audio input socket. It was built in 1999 and I am sure we didn't have digi boxes then. You have a choice; Purchase a BNC/Phono to whatever socket in in your decoder/dvd thing or purchase a new TV.

Save you time and money on a tcon board. Chances are it's not defective, you have a bad panel, this has been a common issue on this model TV, will be intermittent with horizontal lines, unfortunately it'd not fixable. You can take the frame off and try moving around the connectors going from the panel board to the panel and see if that makes it have the horizontal issues, sometimes some glue can be applied for a temp fix.

This is not something for the average person to do. You need to be able to use a soldering iron. You need to be able to look at parts on a circuit board and identify them You have to order the parts and remove the old ones and install the new ones.

Is it possible the hard drive was deleted?

A blown capacitor or resistor, or an IC with a divot in the middle. https://www.fixya.com/support/r29790007-repairing_own_television ..

It amazes me how many people change boards not knowing much about fixing TV's or how the boards work and what each is supposed to do, such a waste of money. According to Sony service information you're getting the code for over current draw of the LED backlight circuit. Several diodes in the strip are bad, this set is edge lit it only has one strip with a defusing screen to spread the light. IF you can find a replacement strip that should fix the set but like most Sony parts they are expensive and hard to find in a lot of cases. If you find one another thing to watch for is getting the defusing screen back in correct or the picture won't look right, also the screen is quite heavy in this set and must be handled with suction cups, if you try to remove or replace it without them there is a good chance you will break the screen.

Bad disc or older player that does not recognize the higher-capacity/dual layer DVDs if that is what the movies are burned onto, most likely.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

Good luck finding parts for a 20 yr old set

Try a different tcon board

Chances of fixing the set are slim, I think you have a bad panel
