Sony Bravia KDL52EX700 TV shuts down with 5 blinks

Note: My TV is a Sony Bravia 52" LCD TV (not available in device selection)

After being on for several hours (can be as long as 6 hours), my KDL52EX700 TV shuts down with the 5-blinks error. After several hours/days I can restart the TV again but it continues to shut down (almost as if it is overheating) after several hours.

I've done a Factory re-set but it still shuts down.

Using the Sony remote I was able to obtain the following error codes:

HFR_ERR, 170626113541 (error history; only one record), 10 (error count)

P_ID_ERR, no error history recorded, 12 (error count)

After a recent restart and a subsequent shut down, the error codes were the same as above and there was only the single error history recorded (i.e. no new failure date and time).

Any assistance would be very much appreciated regarding which component I need to replace.

Hello Dan,

Thanks for your recommendations. Apologies for my late response. I was unable to respond until now. I took off the back reseated all the cable connections and inspected the boards. Nothing obvious that I can see. I’ll try and upload the photos of the boards. If they don’t upload perhaps I can email them to you.
