Question about Sony FD Trinitron WEGA KV-34HS420 34" TV

Sony FD Trinitron WEGA KV-34HS420 34" TV blinks 7 times

I am interested in any known HV problems that would cause the relays to cycle and end in led blinking 7 times when the set is powered up. Is this only an indication of HV in excess of 33KV?

Where can I get a copy of the schematic?
Thanks

Yes this is normally an indication that the HV has exceeded 33,000V. The first thing to check is the rgulator circuit. If you plan on attempting this repair yourself, please udate this and I'll look up the specifics.

If you need the service manual, perform a Google search. There are a number of sites that have the manual available for sale. I am not aware of any free site that would have it. THe cost should be around $10-$15.

Do a google search for SONY LED BLINKS and select the second choice in the list. This is a known problem with these tv's it will require the two 18 pin IC's replaced on the D power board.

Hello maymet,

This sounds like the HV protection circuit is cutting off the TV due to a high current event in the set. This could be a problem in the High Voltage section of your TV (Horizontal output transistor, Integrated High Voltage Transformer, and y of the deflection components, and or the CRT in cases of shorts).

I would suggest that if you do not have a background in electronics, you should have an experienced TV technician troubleshoot and repair this problem.
This is due to the nature of the dangerous voltages that are present in the television.

I hope this helps,

Thank you,

Seven Blinks: High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into shutdown. Check power supply and horizontal circuits.

The power supply board is failing. There are twi integrated circuits in the horizontal drive circuitry that have to be replaced. The original integrated circuits are the same type and you will see written on each..."MCZ3001D" and need to be replaced with Sony # 670581001 or the "D" board with those parts on it needs to be replaced. The cost of the entire board is high-about $375.
