My son stepped on a remote control for a DVR. The Sony Trinitron Wega KD 32FS130 went blank. Now it won't come on, goes into standby mode, with the red light blinking four times. Any suggestions?

Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

The retuning process is as follows:

1. Press the [i+] button on the remote control to display the DIGITAL INFO menu.
2. Press the BLUE button to display the MAIN MENU.
3. Press the UP or DOWN buttons to highlight AUTO TUNING then press the OK button to display the AUTO TUNING MENU.
4. Press the RED button to start the auto tuning process for all available digital channels.
5. Wait for the process to complete.

If toy wish to CANCEL the auto tuning process whilst it is processing then press the BLUE button at any time.

How many times red light blinks when TV lost picture? There would be interval of 3 seconds in red light blinks so count pause to pause and let me know.

your video circuit is not working that is why you are not getting picture

This is answered on the sony support pages see
http://www.sony.co.uk/section/contact
and then enter 're-tune digital channels' in the search by keyword box for the explanation.
It basically needs a software upgrade which will be downloaded free if you've still got a freeview channel - but if you've lost them all you'll need help - anyway it's all explained by sony.
