Re: Pioneer lx6090 2 x flashing red light at start up
Another nice read with a positive conclusion. Cheers for that info Tom bout outside pins of the fets talked about as low to s/c due to the design of the circuit. One to remember.

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 ��....Leave a comment:

Re: No picture Bush BPDP42HD2
Another tv engineer is testing a set overnight tonight with full working set of boards and is gonna send them to me if they test ok. Its a bit of a head scratcher. I tested the original y buffer for shorts and it tests ok which makes me scratch my head even more. The tv has same fault with xsus disconnected. The ysus board supplys the xsus on this set so its possible the xsus has taken out the ysus or vice versa. Fets on the ysus board and the replacement xsus appeared to have shorts on at least 1. Anybody had a similar repair in where the psu board...Leave a comment:

Re: No picture Bush BPDP42HD2
Hi this is exactly what I got with my set as Ron77 said. I replaced all 3 boards resulting in the same fault. The plasma panel itself gone faulty then? £60 later in boards in outa pocket n still looking at an old 28"cry. One of those unlucky years am having. ��Leave a comment:

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 ?Leave a comment:

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...Leave a comment:

Re: New Members - please post your introductions here
Hi. Im 42. I started by ripping apart anything electronic that went faulty. Weither it was a cassette recorder, tv, amplifier, vcr etc it didnt matter. I had the bug to fault find at a very early age. 13 yrs old. Then was recognized by a company who found out i was repairing stuff for people for nothing. VCRs with mechanical faults, Cassette players with faulty lcd wakeup timers/alarms. I studied at college then done my time training as a bench technician then jobbed around the globe for agencys doing SMT repair work and debug...Leave a comment:
