My friend had a plasma tv and said it was expensive to repair when it
broke down.  Do these things break down more than regular television
sets?

Any help in troubleshooting this TV is appreciated. Fuse is good,
horizontal output is good. I have 154v on the collector in standby so
my power supply is good. I'm thinking Flyback or HV splitter. Thanks
for any help.

my sony dvp-ns41p dvd player from costco stopped working after about 1
months with a "can't read this disc" type of message and after takin

I am looking for a supplier of this part. MCM doesn't stock and two
are needed. I've found it from one supplier and they want $20 each
(their prices seemed high compared to MCM on equivalent parts). It is

out) for maybe half a minute - then it gives one big jump and then
it's okay for a long while.

graphics have static in them, is this normal. thanks

Hello group,
I am repairing a failed JRL-2000F HF linear amplifier. It employs 48
mosfet (2SK408 and 2SK409). The symptom was power unit shutting down
because it detected a short circuit in the amplifier boards. I knew

I have a Watlow F4 Temperature controller (full Part No. F4PH-CAAA001RG). I
want to connect a solid state relay to its "Switched DC" output so I get
zero crossing switching but I'm unsure if this requires a SSR with random or
Zero Crossing switching. The manual doesn't help:

Cut out in use then came back.
Next time failed to give output but owner noticed clip light in pre-amp
functioned as normal
Now I have it, I cannot induce it to fail.

Not sure if this is the best group for this.  I found several articles
on the process of using an ATX power supply and convert it to a bench
supply.  The problem I am having is that the wire color codes and pin
