Question about Sony FD Trinitron WEGA KV-SW29M50 29" TV
Its start because of lightning.. After that day my tv get the problem...
The 2 blinks is a error code, it usually will NOT point to specific parts but will indicate area the problem is in, I would suspect it will be power supply related.
If you call Sony or a authorized dealer they can access the data base and see what it means-----almost certainly the set will have to go to a shop for repair.
I did in our shop recently have a Sony with a start up problem and when I found the code it pointed to 3 small parts in the power supply and said replace all 3 (about 10 dollar part cost) and when installed set worked fine.
This can be found and fixed, cost will of course be a concern.

Pls check following area.
Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

I know this isn't what you want to hear, but the problem you've described can't be fixed with troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.
If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please let me know if I can be of further assistance.

your tv has a power supply not working. plse take it to a shop and have it repaired.
ask the tenchnian to check the ht high tension voltage of 95-105 volts, if this is not been produced from the supply then that confirm it being fault.
he should check the semiconductor of the supply.
your supply will stay longer if you power it using a 115 volts on the in put of the supply not 220 volts. because 115 is the minimum and 220 volts is the maxmum.

SOURCE: Canno turn the tv on.
You probably have a main or high voltage power supply problem; the latter produces the 20,000 plus volts for the CRT and gets its voltage from the main supply. It's difficult to say which is at fault without a few measurements.
