Hi Magic - Hope yoiu have some majic for me?! 4 yr. old Triniiton just went out and I have a pregnant wife (37 weeks) that can really do nothing now buy hang-out on semi-bed rest - and I really! need a TV.
Same issues as everyone else. No warning - pop and no power on. I have heard D-Board replacement, capacitor replacement, etc.
At 250+lbs this is not something that I relish pulling out of the built-in mount and dragging to service? Any suggestions or help?
Called Sony and got the Authorized Service rep. It was becoming obvious that I was going to need a part and most likely a D-Board and it is not worth my time to pretend like I could install it without a lot of cussing and frustration.
$220 for the D-Board part and $260 labor to install (I still have to move the behemoth out of the built-in wall unit!!). This solution on carries a 90 warranty on parts and labor so.....if this happens again - well... let's leave that polite discussion for another time.
(PS - turned the TV on this morning and it powered up??!!?? Now I am afraid to turn it off again)

Your power supply board is dead, do you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
no ....the tube will end up after 20 yrs in 10 yr old sony... it is worth if u fix it. randomly going black means...horizontal driver trans former is the problem..or any loose contact with the 110 volt supply to that transformer,,or any loose contact with line o/p transformer.. (horizontal driver transformer may be gone then tv behaves like this) if any other parts gone tv wont come back.... there may be a loose contact call a service pro..
This could be a scan amplifier failure, and there is a loss of high voltage to the CRT. Part of the power supply may have also failed. In these sets, if the CRT emission goes low in emission, or the CRT goes defective, the bias supply to the CRT will go in to protect.
An experienced TV service tech can troubleshoot the set and give you an estimate for service. Considering the age of the set, the cost of service may not be worth it.
The 6 or 7 blinks usually indicate a problem in the horizontal circuit. Since the TV recovered once, the problem is most likely to be a bad solder connection in that area. If you can solder, resolder any connections on the board that appear grainy or have rings. That may resolve the problem. If not, update this and we'll look elsewhere for defective parts.
