A lot of people on this site have this problem, including me. Usually a problem in the convergence board, requiring fixing (not expensive, really) or replacement (about $80 DIY). In my case it was a coolant leak.

I have a pth5498 when u plug it in tv doesn't come on just makes clicking noise no tubes light up or anything just sound and front power light....


There could be many items that can cause that symptom. However I always assume convergence on any rear projection which can easily be checked by unplugging the convergence amp board and then plugging in the set and press power , if the set powers up turn it back off, and you will know the convergence ICs and associated resistors on that board have failed. Although its easier to replace the board unless you have good soldering skills. I am pasting a pic of the board which is suspended above the main chassis just mark the wires then unplug the set from the wall first, but then unplug the wires from that board and then try powering up the set.if you need further assistance , respond to this same post slinteriors_21.jpg

The STKs are common and if you have an experienced electronics tech around they can replace them for much less money but the tech must have advanced soldering and IC exchange experience.

The STK ics, two of them, can be purchased on line for around $20 to $40 each.

http://www.partstore.com/GetModel.aspx?MfgName=Toshiba&BrandName=Toshiba&ModelNu...

Partstore has two models available - one for around $40 and another for around $55.

The part number is STK392-110 and if you google you can find them for as little as $6/each but I don't recommend the cheap ones as they are not reliable.

It takes a good tech around 3 or 3 hours to take the old ones out and solder in the new ones. Also, it is likely one or two resistors are burnt and will need replacing as well.
