Re: Bush BPDP42HD3

hi i have a small squeel. its like a transistor failure on the y sus board. my tv is exact same model as yours. picture no sound. was on when it happened. faded out then black. checks i have done as on switch on as follows are:
VE - ysus
voltage increases and u hear the crackle of the panel switched on then the little squeel of a component and volts drop out away to 0.

VA - ysus
does the same. voltage appears then drops out to 0vts. The tv stays on with sound present.

the psu board
when xsus and ysus unplugged the VS voltage still drops to 0.

im stuck and ordered a ysus buffer and ysus board. going to order an xsus board aswell at some point and will fit them all at same time. ruuning low on funds right now. im now paranoid that the psu board might have a fault. but the tv stays on . so im assuming its ok. the relay clicks 2 times when its switched on. the logic board does a slow flashing sequence. when this happened out of a stab in the dark coz it was cheap i tried a new logic board but still the same. so far spent £40 on it and still to get an xsus board for it before fitting the 3 of them. Ide appreciate any help and input. right now im watching the footie on a bulky 28" crt gutted

Re: Bush BPDP42HD3

I received a y buffer and y-sus board today. Im waiting on a x-sus board now. Ive been going thru the forum trying to accumulate as much info as I can on diagnosing this fault. When i receive the x-sus board im going to replace all 3. Can somebody help tho. Is it most likely that the psu board is fine since it switches on ok and stays on ok and doesnt trip or anything ?

Re: Bush BPDP42HD3

Still stuck with this fault. replaced 3 boards. no gaurantee that the boards were actually good tho coming from ebay. Can i do the forced pattern test on this set with the logic board?

Re: Bush BPDP42HD3

Got 3 working boards from same guy who was even good enough to test them on a set overnight before he sent them to me. Y buffer, ysus and xsus boards. Tv fixed now. 3 previous sellers sent me faulty boards. talk about being led up the garden path with different faults!!! This is a horrible set to work on. Pointless chasing and replacing faulty components on each board coz they sustain multiple faults usually stemming from blown fets. Best replacing the 3 WITH known working tested boards. Can watch rest of euros and Wimbledon now on a decent screen ��. Job done.
