Replace the horizontal output transistor (Q502) and check the electrolytic caps in the vicinty, unsing an ESR meter. PLEASE NOTE THAT THE TV TUBE MIGHT BE CHARGE WITH ABOUT 27,000 VOLTS.

Hello

Blinking of standby light in Sony TVs are fault indications. You just count the exact number of blinks occurs at a time after switch it ON. Switch it ON and OFF by its front panel power switch, and not by the remote control handset. Do this for at least four times, count the number of blinks, confirm and inform me. I can then locate the fault section of your Tv, seometimes even to the exact point of fault too. OK

Happy New Year

RC codes for ge-24914-d to control sony Trinitron TV KV-27S42.


the codes for sony are 0128, 0013, 0002, 0071, 0380, or 0152
1) Make sure the tv is on.
2) Press and hold the set up button till the red light on the left hand corner stays on.
3) Then press tv then release quickly so that the red light flashes once. (its pretty quick so pay attention).
4) Then enter one of the four digit codes and the red light will turn off.
5) Then press channel up.
If it goes up u have the right code. If not start from the begining (holding the setup button down) and do the same steps for each of the codes, one of them should work if not u have to do a code search. Follow steps #1, 2, 3, and 5 but on step 5 press it repeatedly (for up to 300 times and it says that on the instruction manual) until the device can be controled. The red light blinks then stays lit
6) press and release mute to install the code. The light will go off.
