Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television
I believe I fixed the solder pads and the tracers that were damaged, I tested the set and still have the three blinks for the convergence board. I've read up a little on using my multimeter and was wondering if you could reccomend any resources that would give me enough detail so that I can begin to check the components that lead into the chip, I have the manual, schematics, a multimeter and most importantly time. Im currently not confident on how to test them safely with out creating a cascade of new problems. Also there are four 2.2Ohm (i think) resistors in circuit to the IC that have a slight browning around the center (not the indicators bands), other resistor with the same markings do not, I don't believe the brown to be excess flux, is this an indicator that the resistor is shot? Again any feed back is useful, I know this is a large task to take on for a novice so any basic info or refrence material would be appreciated. Thanks again, matt
P.S. - this TV is quickly becoming my white whale.
Yes those resistors are open. If you remove 1 leg of each of those resistors out of circuit then test them you will find that they are open, replacing those with the same rated flameproof resistors should solve your problem. You can contact me at firstname.lastname@example.org and I will send you some Ebooks that will give you some basic instruction on electronic repair. I have a wealth of information and I dont mind sending you whatever can help you learn electronics. Its a fascinating field.
