Yes they are bad, they are surface mount on the digital board. Board replacement is advised. They are not easy to change if trying to replace the capacitors.

Basic cable scrambled on ANT input but not PIP

it sounds like you have the common problem with these models. The poblem has occured so offten that toshiba issued a service bulliteen about it. There is a problem with a cuircit board called the Hypermodule its a signal processing board/ the ideal situation would be replaced this board but it has happen so much it may be difficult to find this ooard so this board can be repaird. The secound problem is to fix this board 11 very very small parts called capacitors need to be replaced. i have also replace these and only someone advance in solder should attempt it very small. twezers and magnifer. You can hire someone but it very labor intensive. Our shop charges 300 just in labor It can be fixed but I would adviise its just no worth it

Toshiba 57h81 location of hyper board and remove procedure

Hyper board is located directly behind the input board, this is where all the tv conections are, then they are two tabs soldered from the bottom of the board then it simply unplugs, But replacing all those capacitors on that board can be a little tricky, replace all 10up @16volt caps and that usaly repairs the board

Picture Jumps/flashes for first 5 minutes

There is a module called a hyper board that is vertically mounted near the jack panel. Inside the module are 10mf/25v capacitors they are grtting weak. The module is fully shielded and pluggs into a socket. the module has 4 tabs (2 on each end) that must be unsoldered before it can be unplugged. This repair should be done by a qualified technician. The caps are surface mounts and very small. Unless you have excellent soldering skills and a rock steady hand DO NOT ATTEMPT to repair this problem on your own.

Toshiba 57H81 picture bounces. Can't tell if horiz. or vertical.

Unstable picture, wavy, jittery, and loss of sync are a symptom of bad capacitors in the hyper module. The problem is worse when the set is cold, but when warm the sympton gets less or goes away. In the latter stages the problem never gets better even after the set has been on for hours. There are about 6 surface mounted caps (10mf/16) inside the shielded Hyper module. The module is vertically mounted behind the jack panel and can be unplugged from its socket after unsoldering the 4 anchor tabs on the bottom side of the PCB. This type of repair should be made by a qualified technician do to the complexity of chassis removal and expert soldering skills.
