This "cracked board" thing is almost 100% of the problems with the little micro TV sets I collect. Dirty pots....and almost ALWAYS some crack somewhere around the flyback. These little tiny sets get tossed and dropped alot, and the flyback is the one item with enough mass to cause a break in the board.
Little wires from some solder point North and South of the break will almost ALWAYS get the little bugger playing again. Put on your GOOD eyes when looking for these cracks. If in doubt....put your meter on the little beep/diode/resistance setting...and check for continuity between a North and South point of what you think looks like a break.
If you use little wires for jumpers....make sure they are insulated unless it's a very small low voltage jumper. Try and keep from bunching any of the wires close to eachother, especially around the flyback traces.
Very small sets....or anything you suspect was dropped, you have to check the CRT socket and anything like a "neck board". PULL the board from the CRT socket and see all the pins ARE there and not broken off...and then check for cracks on that CRT board. This is a good time to also make sure a drop hasn't broken the VERY end of the CRT off and LIBERATED the vacuum.
