Re: Panasonic Plasma fault

I dont buy from monitor9 anymore. They sent me a 30 batch of fake FGD4536. Got my $ back . No hole, or divot in the middle.

Re: Panasonic Plasma fault

Attached you can find a service manual for the 42" version of the VT30E variant. Keep in mind that the E in VT30E stands for Europe, so yours may be a bit different in the power supply area (I imagine you do not have the European variant).
Schematic-wise it should be similar to what you have but do not take the data as 100% since I don't know what differences can be between them.
At least you can get a better understanding (if you have the skills) as to what does what and where/why.

Whos the Guy?

Look in the 10X picture attached by tvtimmy and you'll see "the guy" in the background as watermark...

Re: Panasonic Plasma fault

I get mine from......

Re: Panasonic Plasma fault

These are the ones I have used for years.

Look at mine haha. No hole and look at the shape.....
Im not going to use them.

The guy is the person where you bought it also from on ebay.

Re: Panasonic Plasma fault

You will need to use the original parts for replacement. Moreno, I told you to buy the fgd4536 from "the guy". I have never had a problem with any of them. I have a 55" up on my buddies wall, at his tavern, that is running 14 hours a day on max brightness. I can send you a pic of mine to compare to yours if you need.

Re: Panasonic Plasma fault

Dont know , you probably need the original ones.

I also ordered the fgd4536tm from monitor09 but mine look different from the originals....im afraid to use them.
Do you have a picture of your FGD4536TM? A non soldered one...

Re: Panasonic Plasma fault

Just found a couple of cracked ics r5207a and c08n25 the first tests ok still but the latter is open on all legs..are there any good or better chips to replace these bot with?

Re: Panasonic Plasma fault

anyone ever seen that before?

[boomtheroom]

Re: Panasonic Plasma fault

found a short on one of the white plugs that connects to the lower buffer board bit of stray solder was shorting 2 pins..removed that reconnected now i get this!!!

Re: Panasonic Plasma fault

Took the board out retested resistors, diodes ,transistors.. couldn't find anything so put back in and turned on .. now getting 6 red flashes?????

Re: Panasonic Plasma fault

That's the way to go. It would help you a lot if you find the proper schematic for your TV or board and check the values of the resistors against the schematic values.
Check all diodes and transistors, including those smaller ones that are not "power parts".

Re: Panasonic Plasma fault

I had a short private chat with @boomtheroom before he started this topic and I tried to help him since he had the same problem as me: bought a kit, worked for some time and blew up again.
I suggested the replacement with FGD's from monitor09 and he did that.

I support @Morenos83's advice to re-check everything on the board(s). It is very possible that you have some resistor or capacitor out of spec and it messes with the end result.
Also, don't forget to clean the screws, screw pads and TV chassis contact points as leaving any of them scorched will get you into trouble again, fast.

will do.. all the other boards seem to be ok ... no shorts. getting the power they should no bulging caps.. so will revisit the sc board

Re: Panasonic Plasma fault

nah replaced the cheap parts with good ones..still no go..

Yup but you used fake parts on the board which resulted in more damage to the board. I see you used the FGD4536TM to replace the bad parts.
The problem with bad parts is that they cant handle the load and literally blow up and take out other parts in the same trace.

In europe the voltage should be around 215V on the prong connector.

There are more parts defective on the board , could be a resistor but you need to measure every single part......
Could you check for shorts on the SS board?

[boomtheroom]

Re: Panasonic Plasma fault

any idea what the voltage should be at sc2?

[boomtheroom]

Re: Panasonic Plasma fault

The cheap parts that blew up did more damage to the board. I cant find that model number here in the USA to look at a pic of your board.

hers a pic
