Re: Panasonic TC-P42S30 Standby light



From their message: "It is extremely unlikely you need replacement diodes, for example. They hardly ever go bad - mostly when people try to desolder a leg from them to see if it is indeed shorted."...

Re: Panasonic TC-P42S30 Standby light



I took a quick look and they seem to sell a lot of individual components so it should be easy to add to a kit. Thanks....

Re: Panasonic TC-P42S30 Standby light

I messaged the company that was suggested. They don't carry the diodes or resisters. They also said that diodes don't go bad until people try to take them off the board. I really don't want to buy a kit and then have to buy another with the components the first one doesn't have. Does anyone customize kits with the parts you want not just what they think you need? I know that some parts will test out OK because they are in parallel but I'd rather pay more to have everything I may need before I start.

Re: Panasonic TC-P42S30 Standby light

Thanks Mr. Barton. I think I will replace all the 000 and the Q451. I found a magnifying glass and 401 and 402 are supposed to be 7.5 so I will replace those as well. Does anyone know of a kit with all of the below that you feel confident are a quality product. If any of you rep these I am asking you were not selling. Thanks again for any help.

I have been reading the board for the last couple of evenings and have found some good stuff but I want to get some input from you experts because I don't know Jack about electronics.

The TV is a Panasonic TC-P42S30 that only goes to standby when turned on.
After reading the forum I disconnected the SN board and got an 8 blink code.
I tested some of the components on the SN board (TNPA5349) and this is what I got:

SN 2 - .5 Ohms

Transistors - I tested back to each leg in diode mode
