it depends if its just that input or the whole tv itself if it works on other inputs it may not be to bad to fix, but if its the tv itself it depends on how old it is and how much you paid. it could wind up costing quite a bit. so take all those things into consideration. it might just be time to upgrade
Usually, the L01-1 chassis most common problem = weak
capacitors, such as C2455.Could be C2425......47mf/25v...
Check all caps around horiz drive xformer = an ESR meter

If your TV uses the CTC 203 chassis or similar one, you more than likely have a loose solder joint on the horizontal output transistor base circuit. It's a little inductor (coil covered with red epoxy about 1/2 in. long). If this coil opens up or stops making connection, you lose the horizontal drive pulse to the horizontal output transistor thus causing the screen to go black due to the loss of high voltage.
