Question about Sony FD Trinitron WEGA KD-36FS130 36" TV
SOURCE: Sony Grand Wega KDF-E050A10
Authorized sony repair center told me the problem was the Q Box. Ever
heard of this? Part runs about 300 bucks. TV is out of warrenty as it
is 2 years old. Do you think it is worth it to fight sony and get them
to replace the part or just fix the TV?
Part Number is A1167541A, service rep called it a Q Box in the diag, however the web says its the b block assmy.

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 2X blink indicates that either the Horizontal output transistor is shorted, or the RGB amp is shorted (on the CV board).
The Horizontal output is probably the cause, and as a general rule, the flyback should be replaced along with the H-Out transistor. Good news is that Sony is pretty good about having parts in stock. In fact, a lot of times they will have the A board with all the parts on it for only a few bucks more than just the flyback, so you basically get a new TV (electronics-wise).
Any decent repair shop should help get the parts/do the repair for you if you don't have the electronic experience.
Hope this helps you...
