Check the diode and transitor associated with this circuit. Mostly in the EHT transformer side. Better replace with a identical type. It is difficult to find the leakage in the diode.

Unless you rectify this, any number of times you replace the power transistor, it will immediately get shorted!

Lg 21 inch platron crt tv eht high ocilates,110 volt ok ,dt changed

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.

Give a special attention to its horizontal output transistor. Replace it, and check. Check this device for collector to base, or collector to emitter leak. Even a slightest leak, will cause sivere problem.

Sharp tv primo 21`inch turn on red light only

check your horizontal transistor maybe it's shorted replace horizontal transistor or maybe the fusible fuses are open check for open resistors at the horizontal section of the circuit.

SONY KP-61V90 tv will not power on, red light in front,

Its 2 times blink error code that shows +B volt supply (+135 volts) is shorted, most probably horizontal output transistor is shorted, replace it.
If you are good in soldering parts in circuit board then take out horizontal transistor, check it, found shorted then replace it with same number.

Horizontal output Transistor Q502 number is 2SD2578 and available in Part Store for $10
Let me know for further query, if any.
Thanks.

We had apower surge while watching tv. now there is no picture, but we can hear the program.

This could be the tuner damaged or a regulator damaged depending where the surge entered the set. Lighting will damage tuners while line power surges will damage regulaters and often horizontal output transistors along with sweep mode power supplies. Since you have audio I would suspect the horizontal output transistor first and check it from collector to base and emmiter for short with a digital volt ohm diode check meter. Check with diode check mode.
