I seem to have some

I seem to have some difficulty finding the correct PICO fuses, probably because I don't know what I'm looking for. I find TONS of 125v rated fuses in both 3.15 amp and 5 amp, but none of the voltages involved even approach this. (Ok, obviously I know nothing about electronics!) Can someone please advise what type of PICO fuses (voltage rating as well as amps) and perhaps where to find them?

p.s. Larry, I also emailed you directly at the advice of the gentleman who runs that parts website. Sorry if that was intrusive.

I do not worry about the voltage only the current. I do however always use a high voltage then what is in the unit. But always the SAMe current!

Finally got it done... worked

Finally got it done... worked like a charm! In my case, no blown PICO fuses, just the ICs were bad. Replaced the ICs, (sounds easy, but it's a pain in the.. ummm... neck!) powered it up and the picture was perfect. I had to solder the ICs with the board still attached at the high voltage cable- couldn't get the doggone thing off... but it worked out ok.

I chose to ask YOU because

I chose to ask YOU because you seem very knowledgeable and helpfull !! I have an AVION LTV-320

 LCD TV (Model name/# is LU32a1a3). It was given to me as a partial payment for some money owed 

to me, anyhow, long story short there is no power cord nor a mannual. I have searched everywhere

for the power cord and can not locate it! Not even a website for this brand of TV to ask for parts and

accessories! Do you have any clue as to where I begin my search! Thanks a million! Danielson

Hey Larry i have a question

Hey Larry i have a question for you . Its about a Mitsubishi WS55315 . My problem is the green power light comes on at plug in . Can't turn it off as power button has no effect . Also no pix no sound either . I have noticed i have the 12v and the 5v lines . I am assuming the processor is bad . Have you seen this problem. I am a tech but have no service manuel on the model nor have i seen this chassis before . Thanks for any info you might have as i see your a mitsubishi guy who knows alot about them . James

Hi

Hi
I am having similar issue, where colors do not align. After using your instruction above, it stops at the grid (after pressing 6). Not sure what you mean by white cursor, I do not see any. I have also noticed that the convergence issue going away late in the evening. Please help.

replace the convergence iC's

replace the convergence iC's before making any major change in the adjustment or i could be really hard to adjust whn the set is fixed propely, the adjustments are there to do minor shift changesdue to aging parts, in the convergence NOT any major change in the convregence, replace the IC's first.

It seems you are the only place to get real help. I read through all this and understand it. I just replaced the IC's and am able to move the curser now. But it just moves the lines and not on the picture. How do you move the colors around? It said in a counter clockwise direction from the center out, but move the lines to what? When I do move the lines, the light greenish yellow 6
