Its probably going into protective shutdown ue to an over voltage condition in one of the operating circuits. My guess would be one of the regulator transistors or a leaky diode

I have a old 52 inch sony tv turns on but picture blinks off and on whats wrong


A lot of their older sets (both regular TV sets and big rear projection set had this issue).

In either case it may mean with age the MASTER SCREEN control/s need to be adjusted slightly up---if too dim a picture it will blink.

A model number would tell me what to try.

Models beginning with KP are large projection and ones with KV are regular sets.

I have a magavox big screen


Hello cce357,

This can be any number of things, here is a possible listing:

1) No High Voltage (check the IHVT or the trippler)

2) CRT filament transformer winding open (check the windings that supply voltage to the CRT filaments)

3) Video / CRT socket boards bad (highly unlikely but check anyway)

4) High Voltage power supply malfunctioning (related to problem #1)

This listing is a good starting point. I would suggest that you purchase a schematic to aid in testing the voltages mentioned in the 4 steps above. If you have a background in electronics then do the above, if not please ask a qualified TV technician to perform these steps.

Thank you,

I hope this helps,
