Question about Toshiba 55H70 55" Rear Projection Television
Whenever you walk close to the tv it goes out of convergence. I can adjust the tv but mother in law is 300 lbs and frequently moves around room as so tv mess up picture.
Solder connections to the convergence stk ic chips have developed ring cracks most likely. The chips will fail if not resoldered. The chips will be mounted to large heat sinks and have stk392-110 or similar marked on them. You will need good soldering skills or professional help is in order. The chips are prone to failure for this reason. Unplug the AC cord before attemping to open the TV . You will need to gain access to the bottom of the circuit board the chips are mount to. Unplug the electricity...did I mention to unplug the AC three times??? Yes ;)

If you have noticed that machine is vibrating when it
is running then the motor /drum suspension has to be inspected. Since these
fittings are located on the underside of the machine it is important that you
look for the noise with a good inspection lamp. Manually turn the motor and
drum and listen for the noise, if so the motor bearings, the drum agitator
shaft and fittings must be checked. Also the suspensions which include the
shock absorbers and springs, the body clamps must be checked to be in correct
alignment and not changed in position. Tightening of the mounting is also very important. Finally in most cases
a drop of OIL or smear of grease on the moving parts cane solve most issues.

The anti-shock poles offer internal springs that absorb the shock when you walk downhill. In most anti-shock poles you can turn off the anti-shock feature whenever you like. The anti-shock feature is recommended if you have weak or damaged ankles, knees or hips.
