Re: 1996 32" Sony Trinitron Suddely looses power
The most common problem for what you've described could be a failure of the HOT (horizontal output transistor Q502 which also includes the following components as well.
Q601 & Q602 (2sc4834)sony p/n#8-729-019-49
R607 (sony p/n# 1-202-933-61/ [email protected]/2 W)
C615 (sony p/n# 1-136-759-11/ .039mf/630v)
So common is this type of failure that Telematics used to sell a kit with these parts as a primary repair for this type of failure.
The HOT, both vdr's, the resistor and mylar cap are not expensive, the but installation and testing is quite involved. These may not be the only parts in solving the problem and if you're lacking any skills or equipment to make these repairs yourself I'd strongly suggest having a reputable shop do the job for you... It shouldn't be too costly and quite a number of shops may have the parts necessary on-hand. This model sony is a good Tv and the repair would clearly be worthwhile.

The TV circuit may have detected a problem within its parts. You may have to check some leaking capacitors in the board or loose solders or burned components just to make sure. Normally leaving the TV unplugged overnight should reset it.
as set is dead
the problem is in power supply or horizontal section.
though it is a simple &less time taking.
but if you have no TV repair experience, or any experience tracing circuit flow with a schematic, call in a tech to assist you with this repair. This tv set is not the place to be experiementing inside of. You probably have bad capacitors and transistors in the power supply or the sweep power supply.
The most common problem with TV was the failure of the Horizontal Output Transistor, this will also damage 2 transistors in the power supply and a resistor in the power supply also. (From memory): Horizontal Output location # Q501, 2 power supply transistors Locations Q601, Q602, and resistor Location R607. Also solder the Horizontal drive transformer, you can find it by following the circuit board from the base of the Horizontal output. Some models used an IC instead of the 2 transistors in the powersupply, it will have six legs and check like 2 transistors. Good Luck.
