Need resistor help

Re: Need resistor help

Sorry for all the stupid questions I'm a noob just trying to diy my tv since money's tight so can't afford a new tv.

Re: Need resistor help



So based on the info these should work to replace my two blown resistors.

Re: Need resistor help

Are you sure that MOSFET is not also shorted out, or the circuit that drive that MOSFET is not bad?

[Fordman]

Re: Need resistor help

No I don't. WhenI plugged in and turned on seen the flash abs pop of the resistors so just thought only that bad.

Re: Need resistor help

You better check all those parts in that section.

[Fordman]

Re: Need resistor help

Ok I'll check that out before I order parts. Think these are a better match than the others lifted.

Re: Need resistor help




I checked the Q16601 mosfet it checks out fine what else do I need to double check

Re: Need resistor help

Ok I'm stuck on what way to go need more help. I followed this flow chart and unplugged ss11 and ss33 tv doesn't stay on. So per chart removed sc2 and sc20 and now got 6 blinks. So next is to remove all 4 screws from the su/sd boards plus the three connections. Then jumper sc50 and if tv stays on sc is good and su or sd bad but if still no good and 10 blinks it the sc still correct.

Re: Need resistor help

anyone find a replacement for this resistor..go the same problem

any luck finding the r601 resistor replacement?

Re: Need resistor help

If your tv is model TC-P50S2 then I believe you have to put 16 in front of the numbers on the SC board. R601 becomes R16601, D618 becomes D16618, Q601 becomes Q16601.

If this is correct then R16601 is a 1 ohm 0.33W resistor

I would also check all the above components which may well be damaged.

See page 82 of manual

If your tv is model TC-P50S2.............

Edit
I see the resistor values have already been resolved in an earlier post which I missed.

hey thanks for the reply
my tv is a P50vt30z if that makes a difference?

Re: Need resistor help

tested the resistor ang get this reading.. does this mean its not shagged?

There's probably more damage to the circuit than just one burnt out resistor. The board number looks like TNPA5335 BG. If you do a search on this site there is tons of information about this board which appears to be a difficult one to repair.
It would suggest you start a new thread with make and model number and pictures of the board and also any blink code.

ok whats you thoughts on my resister reading?

That resistor shows in the repair manual as:
R16601 D0GF1R0JA047 M 1 OHM,J,1/3W
Your reading shows 20.38Mohms, so it's broken. Mohm stands for Milions of ohms...
I am sure you have more than this simple resistor to fix, there's a reason it blew up like that...
Here's the manual for P55GT30. Maybe it's useful...


Usually the variants ST30, GT30 and VT30 are very similar but not identical.
And yes, dick_barton is right, you want to "read" 16 in the schematics for all parts, ie. resistor marked R601 on your board is named R16601 in the schematics and the tables after that (bill of materials).

Re: Need resistor help

That resistor shows in the repair manual as:
R16601 D0GF1R0JA047 M 1 OHM,J,1/3W
Your reading shows 23Mohms, so it's open.

Hi yea i already replaced 6 transistors tv worked for a few hours the a loud pop ....now flashing 6led flash codes so replaced those same transistors again then noticed that resistor..

[boomtheroom]

Re: Need resistor help

could i use a 1ohm 1/2 watt resistor in its place?

Re: Need resistor help

Just yesterday I saved my TV (TX-P42VT30E) from 7 blinks of death by replacing those FETs.
Did you get the transistors from a kit? If you did, most likely you got some fakes.
It happened to me too, bought a kit, replaced them, TV worked for about one hour then they blew up.
Then I got them from a local Panasonic authorized service for about the same as the price of the kit, put them in and now my TV is alive
