Note: the companion document: VCR Power Supply Hybrid Regulators contains similar information for many of the common parts found in VCRs with linear power supplies.
Much more info on most of these parts can be found on the Net via Chipdir and other semiconductor reference pages. See the links in Sam's Neat, Nifty, and Handy Bookmarks. Consumer electronics sites may have some of the hard-to-find datasheets. For example, for Sanyo datasheets (STK), more info can be found at:
First, check for power to the Vcc or Vss (or whatever) pins. A large percentage of failures will be due to lack of power or incorrect voltages. The suspect device may or may not be at fault. In many cases, a fusable resistor has sacrificed itself possibly due to a short in the suspect part or elsewhere (or opened for no good reason).
However, note that the 'typical Vcc' or other supply voltages listed in this document or the device's datasheet may not be what your equipment actually uses. Therefore, a voltage that is moderately different than the one listed for the device may be normal.
Once good power is confirmed, test the inputs and outputs. Obviously, an oscilloscope is generally needed for these.
Where multiple identical devices are present, substitution is usually an acceptable troubleshooting technique but there is some risk involved as faulty circuitry can blow your 'good' part.

I did a ton of research myself only to find that if you want to replace an LA7835, LA7835-TV, LA7836, LA7837, or LA7838, you are better off using the LA7838 for any of them or paying more for an ECG7104 or ECG7039 instead of crosswiring a SK10085 (which does work. Philips lists the LA7820 listed as being replaceable by an ECG7084 but I have seen it listed elsewhere as an ECG7840 or another transposition of those last three numbers I can't remember.

(From: yonymar@aol.com). The STR80145 is used in computer monitors. It is called a "Hybrid Auto-Switch Module-Doubler". It allows monitors to operate at 110v or 220v without having to use a selector switch. At 220v AC the IC allows the bridge rectifier to function normally and pass the rectified AC to the filter caps, at 110v AC the bridge rectifier voltage is sent to this IC to be doubled to the equivalent of the 220v operation, automatically. The rest of the circuit operates as if the input were 220v AC. Pin 1: Delay Pin 2: T1 Pin 3: T2 Pin 4: Gate Pin 5: Common
