Dead Panasonic TV TC-21SR10M

[echobase]

I owned a set of Panasonic TV TC-21SR10M. Recently the set went DEAD with front LED on and I tried to troubleshoot it. I checked almost every parts of the circuit board, from HOT to power supply section but found all major components were still OK. Can you help me on this?

Sincerely

Unfortunately it may be a minor component causing the problem- these sets have extensive protection built in - it may even be a faulty or out of tolerance comp in prot circuit- if you have led on you have 5v line still- it may be vert circuit, or audio circuit, or control circuit, or dry solder joint, or leaky semiconductor, or hi-esr capacitors, or s/c cap- you really need to take this set to an expert, or if you want to fix yourself, you will need a proper service manual, & the tools, equip & knowhow to fix- it could even be a faulty lopt or yoke- the difference between a n amateur & a professional is experience. Knowing what to test & how to. Safely.

I would agree with Neil, a lot of these sets have complicated bus IC's to work the colour, I've repaired a couple of these sets at great cost, only to have them bounce a couple of months into the repair warranty. The result is an irate customer and a costly bill. For some years now I no longer take Panasonic colour faults, it saves time and money.
