zenith plasma Z50PX2D
Hi, problem is 6 vert lines the width of the screen. Lines are filled with round white dots, also static in sound when dots vary. Anyone know of this problem? -
zenith plasma tv. the model is Z50PX2D.pix problem
hi, i have a zenith plasma tv. the model is Z50PX2D. i really love this tv. as of late its coming on with 6 vertical lines of white dots. they flicker, the audio seems to affected also with static sounds. all other aspects of the pic are good. i have good color, and no other problems with picture. can someone help? thanks. -

o.k. thanks a bunch, guys. -
HP8540P computer
hi, when I plug headphones into the jack the main speakers continue to operate, no sound from headphones. my question is do I have to enable the headphone jack somehow in order for it to work? or is this a hardware problem? -
soldering ic
hi all, on some ic's there is a heat sink on the bottom that is soldered to the board. my question is, can I just apply heat sink compound to the bottom of the ic instead of soldering it? -
explanation of terms
hi all, need to know what the following terms mean: dissipation factor, tan delta, dielectric absorbtion, v loss, memory effect, soakage? also can anyone of these cause a defective capacitor? thanks. -
Re: cap testing
nice meter. $90 bucks, ouch!!!!Leave a comment:

Re: cap testing
hi, I made that one too. but for some unknown reason couldn't get it to work right. if anyone makes a successful build plz let me know.Leave a comment:

Re: cap testing
hi rugger, being an ex service tech for Philips, I accumulated a bunch of defective caps. I saved them. my experience has been that this cap checker lcm3 caught everyone of them. both for hi esr and low capacitance.Leave a comment:

Re: cap testing
let me say there are literally hundreds of pages (forums) written about this meter. I thought somewhere I read that what it was. i'am probably wrong. it can't be series z. what do you think of this meter? worth the effort?Leave a comment:

Re: cap testing
hi, I thought sz might mean series impedance? I think your correct about memory being important in design.Leave a comment:

Re: cap testing
hi, I think sz is referring to leakage. the lcm meter I built shows memory on a scale of 1-99. is the lower value indicative of a better cap. if not important parameter why show it?Leave a comment:

Re: cap testing
hi, does it measure in circuit. under 300mv output?Leave a comment:

Re: cap testing
hi, the meter I built is a Hungarian design. it measures memory, leakage and tan delta along with esr. great meter but kind of tough to get built. has some very critical components. anyway I'm adding an attachment where you find details. use google to translate.

cap testing
hi all, I recently built a esr meter. I need clarification on two of the parameters it measures. 1) memory effect. 2)sz value. also what values of these two would render a capacitor defective? thanks.
