Re: Bush BPDP42HD3

If at least they said "untested" but most in fact seem to claim the boards as fully tested.
I buy from some other suppliers who actually say their parts are untested and offer free replacements (tell you to keep the bad board), they are at least honest!

Re: Bush BPDP42HD3

Can i ask you what there trade name is?

Re: Bush BPDP42HD3

Parts4u.me.uk is one of them, forget the name of some others.
I am going to, at some point in the future, build a search engine for finding TV parts...

Re: Bush BPDP42HD3

Hello,I have all good reading from the psu with y-sus and x-main disconnected
Vs-207.6v
Va-55.2v

If I connect back both the psu starts cliking and the voltages drops .

If I connect just the Y-sus with the ribbon from the T-con disconnected and the X-main disconnected I have constant reading from Vscan -193.6v and Ve-91.1v

If I connect the ribbon from T-con to the Y-sus with the X-main disconnected the voltages drops.

This mean the X-main is faulty or the T-con board ?

Re: Bush BPDP42HD3

You will need to replace at least X-main & Y-main, maybe even Y-buffer

Re: Bush BPDP42HD3

As Tom points out all three board could be faulty? with this model it has been found that a bad X will damage a Y , a bad Y will damage an X and bad buffer will take X and Y. So you now need to check each one for shorts, and when you replace them check replacements for short as well, as a lot of the boards come from damaged screen sets, not testing can lead to damage to you once good boards. the best way is to replace all three with known good working boards. also check old posts for PS42Cxxx models as these use the same boards Flocko

Re: Bush BPDP42HD3

From the picture wich pin to use to check the buffer board please.
1.GND
2.GND
3.Reset
4. 5v OUTL
5. GND
6. GND
7. LE-2
8. OC2-A-2
9. OC2-B-2
10. OC1-2
11. CLK-2
12. GND

I think one is any GND ???

Re: Bush BPDP42HD3

Check out You Tube Tom has a how to test plasma Y buffers, that will show you what you need to know, have you found anything on the X or Y ?

Re: Bush BPDP42HD3

I found x-main shorted at Q4007 and Q4001 both have RJH30E2 on them ,I ordered 2 pcs from ebay for £2.75

I checked the Buffer board and I have found shorted IC .
GND used pin 1 and found on the second connector from the top off the Buffer board and I think IC number 3 is shorted to GND because a couple of pins have continuous connectivity.

Re: Bush BPDP42HD3

That's a good price I don't pay a lot less from China (40p each), but then again X board only £10. So will you be replacing buffer IC or getting another board? whatever way you go make sure that it is clear of shorts before you power the set up, as any shorts will take you back to were you started, and we have seen this over and over again.

Re: Bush BPDP42HD3

I changed the 2 shorted RJH30E2 on X-main ,I got another Y-main but mine was fine as-well.

I order another buffer board from ebay -£15 with different PCB NO but working with bush and samsung . PCB no :LJ41-08594A
Checked and was ok-no shorts on.

Before to connect the buffer board I checked all board and had good readings .

Connected the buffer and TV WORKING for the last days on.

Thank you flocko ,TOM66
