Hi Vinny,

When the standby/timer light is blinking, this indicates that there is a fault with the TV usually in the power supply section. First you need to check if the output voltages from the SMPS is good or not.

Hi Mike,

In that case it could have burn or shorted some components in the connector area. I suggest that you trace to that circuit and check if there is any burn component or component that is extremely hot.

HI mike,

Do you mean it was working fine until you accidentally connected the cable the other way round and now not working?

HI George,

If the tv can run on av mode and only can receive 2 channels then you have to focus on the tuner part. if all the cable and connector found to be good then try replace the tuner and retest. Sometimes channel problem also could be due to corrupted eeprom data.
