Bush IDLCD27TV006 fixed but Freeview crashing

[shepp]

hi, ive managed to fix the faulty power board on this tv, and now it works until i tune in freeview channels, then the tv starts to glitch and then freezes and i have to either turn the tv off then on, or change the input to scart or tv and it works ok but then when switched back to digital its still on the same freezed screen

would this be the tuner board(suspected) or could it be a main board issue, i dont want to order the tuner and it still not work, so anyone with similar fault could point me towards a solution

will crack open again later and take pictures of tuner and main board if needed

Vestel chassis? Reseat the connector from Freeview DVB board to the main board, on mine it was loose and causing random lockups.

tv works fine through SCART FREEVIEW BOX, ITS PERFECT!

but through tv(analogue) and Digital its like theres an issue with the tcon, glitching screen and menus glitching(see pics with the lines), but when through scart the menus are fine and picture is good(last picture)

ive checked all the connections and they seem fine, ive even tried wiggling when tvs on and its not done anything differant, im starting to think the main board might be knakered and thats why the scart works and the others dont

any ideas anyone?

Is it a Vestel?

Are all the PSU outputs ok?

Re: Bush IDLCD27TV006 fixed but Freeview crashing

how will i check that? numbers on the boards are all 05TA(071B power board) 059A main board, and tuner is 05TA092

ill check voltages now...

they all check ok 16V seemed a bit high....20V

but now ive powered it up without the aerial in it its ok no lines or glitching or anything

Vestel have "Vestel" written all over them.

If it doesn't affect SCART, the fault is with the main board, which could be tricky to source. You may sometimes find it by pressing on the larger processors on the board.

Re: Bush IDLCD27TV006 fixed but Freeview crashing

you got me thinking now tho....coz its got loads of G-Luxon caps on the PSU, so gonna try and get it to fault again then retest to see if voltages are all still there and try your pressing method

only thing written on main board is PROFILO TELR@ and the number

Re: Bush IDLCD27TV006 fixed but Freeview crashing

im thinking thats the way to go, probably message em before i buy to see if i can return it if it doesnt make any differance, but fingers crossed that whats up with it

Re: Bush IDLCD27TV006 fixed but Freeview crashing

what does MV stand for on the PSU connector? does it come from the main board or does it supply the main board from the power board? its bouncing around like mad when the tv glitches its only 0.7v when working but im guessing thats something to do with the problem

Re: Bush IDLCD27TV006 fixed but Freeview crashing

think im gonna replace all the caps first!

Re: Bush IDLCD27TV006 fixed but Freeview crashing

yes mate, but it hasnt made any differance

might just give up on this one and sell it for spares or repairs, because it was working fine a minute ago freeview and every thing and i cant get it to fault now, only thing now is the screen stays black for a bit before coming on unless you give it a tap(im guessing ribbons are loose on tcon) but im not stripping it down again tonight

Bad BGA or solder joint on main board... or loose connector...

Re: Bush IDLCD27TV006 fixed but Freeview crashing

whats BGA?

might take main board out and go through it with the solder iron
