Sanyo tv st-21ms22b cant turn on with remote red light blink once and nothings happen.


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

My Sanyo DS32225 worked fine for about 20 hrs.,then NO Picture at all. The sound works fine and it will change channels but not even the menu will come up on screen. Whats up?


they are two things to check, the power supply has a voltage of 90-110volts which triggers a line transformer to oscillate,
firstly check that voltage if that voltage is there then check the line transistor.

Model: CM21AF8A


the picture is produced by the following,
check the power supply, making sure that a high voltage is produced of about 90-110 volts, which later triggers a line transformer to oscilate.
a power supply is suppose to be checked expecialy semi conductors and diodes, also fusible resistors be checked make sure that the switch is okay power is passing through it.
