My 32'' sony wega blinks 5 times

The 5 blinks means a problem in the set's AKB (auto kine-bias) circuit. Sony TV's monitor the operation of the picture tube. When some kind of trouble has been detected, the TV blanks the screen and flashes the 5 blink error code. This may be due to problems in the video circuit, a bad picture tube, or adjustments that have changed due to aging of parts. There isn't anything I can suggest you try on your own to fix it. Because several things may cause the problem, and the proper tools and service information needed to troubleshoot, you should refer this repair to a professional.

Try unplugging the TV for about 10 minutes and then tunung it on again. Try a factory

To reset the TV to factory settings
Turn the TV on.
2 Hold down on the remote control.
3 Press and release the POWER button on the TV front panel. The TV will turn itself off,
then back on.
4 Release .

I'm assuming step 2 means hold down the power button.

Sony FD Trinition WEGA KV-32fs120 32" (no picture)

If the standby light is blinking 5 times then repeating, it is likely a problem in your picture tube or related circuitry. Other possibilities include the "Jungle" IC which takes care of the video, chroma and deflection processes and is a bear to replace. Either way, it could be an expensive repair.
