[QUOTE="muso58, post: 300283, member: 244013"] hi guys , dont know if you can help .i'm trying to work out why my 50vj33 tv has stopped working . as luck would have it just as the 2yr guarantee runs out .i live i n spain and the only tv repair man i have near .cant do it as it wont fit in his workshop ! I am ok with basic electronics ,good at soldering components ( i decode car radios so i am into desoldering eeproms etc .plus i can check basocs like diodes & caps etc . I am hoping maybe this is a common problem on these sets and that someone may have the answer. i came in from work one nite & the wife had fell asleep with the tv on . I noticed when i walked in that it was off & the led on front was flashing ( it never did that before & has,nt since) I switched it off and back on & removed mainss from wall for 5mins etc & later over nite ,but still no joy .it seemed to have intermittent sound at first ,but all it does now is powers up . there is a low buzz coming from the ps board .I have checked the main capacitor as was suggested on another site & it is giving out 295v . this is all i have been able to do so far .i also tried to check the doide blocks ,and i think they are ok . a chopper transistor was mentioned also ,but i can find that to check .I checked the 7v & 11v outputs ,at the connection to the next board & they arent accurate ,the 7v was showing up as 10.5 v and the 11v was showing at more like 12v I have the wiring diagram that came with the set if it is any help . i think my next step is going to be the toshiba agent ,then next stop probably the bin ,when i get their quote :) any suggestions greatly appreciated Steve [/QUOTE]
