Sony Wega KV-34HS420 shutdown

Hi guys... I'm having a problem with this unit. Just shuts itself down about every hour or so, (intermittent). I have opened the diagnostic screen and it reveals as follows..

2: +B OCP 0
3: +B OVP 0
4: V STOP 0
5: AKB 0
6: LOW B 1
7: H STOP 1
101: WDT 0
Serial: 9024519
Model: 35668810

Do you think I'm looking at a very expensive repair. Any help appreciated.. THX

Some of these look like past

Some of these look like past problems my friend.   Have you ever had a problem with this set before.  Cause if you did, this diagnostic screen holds the memory of all the problems .  Go here see how to reset this diagnostic screen, and when it happens again, see what it reads.  Im my opinion, it looks like a power regulator problem or a bad solder connection on the horizontal driver transformer or its circuit and or in the power supplys.  Good luck, and please let us know how you made out.   PS: read till the end to find out how to reset the diagnostic screen to factory settings
