HOT - BU808DF Enrolled in repairing TV Vestel VR2106TF. Chassis 11AK30A11. The defect of this - in stand-by mode BP quietly ' yelps, and the operating mode everything is normal. At the autopsy it was found that the filter capacitor C -827 4700mkf x 16 volt outlet BP vspuchen and it unstable voltage 22-24 volts.

Amazingly, the CTR360 Maestri Two Professional broke in as well as! Rukovodstvo po remontu i ekspluatacii ford focus 1.

When the TV set in working mode it stable nine volts. And the TV is working properly. They tried to replace the C- 827 to a new tank 4700 microfarads at 25 volts - the effect is the same, only now unstable voltage on C -827 from 30 to 33 volts. And in operation again everything is normal stable 9 volt. While others stress how?

Verify the OS - and its optocouplers stud. Show do not forget to put a Q804 and D801 near optocouplers, already two cases for this month The repairs came from a broken back for repairs came from a broken back BU808DFI in high parts.

After replacing the earned but the food at 135 instead of 115V?. BP collected at 44608r40. Des Lombards litas in the primary and optocouplers but without results. He left in the duty room nanoparticles, uprom again croaked BU808DFI in the duty room, when it replaced again 10.2v, listened to him, but he barely audible hush ( in the duty room ), and the collector napruga changes 10.2 - 10.4. Working day and night can work. Vnaydenoy in nete scheme B + = 150V - perhaps it should be for a 51 pipe?

Javascript: emoticon (' [ندعوك أو لمعاينة هذه الصورة]' ) who face, tell me, pliz. Thank you in advance. Check, and better replaced right away cond 10mkf in the basic chain BU808.

The transistor die only in the duty room and not immediately, but since it does not work prikopatsya. Also it was like BU808DFI in JVC AVK14T3. And Litas everything changes, such as required, and 808 normal set (of the same party and with a normal resistance to b -e - in other TV work ) and heating was weak in the office. And fly, too, only with a long work in Dej. Never understood what it was.

And there is resistance in the collector circuit penultimate stage picking (somewhere found on the boards ). Flew only in Dej. All done on line. It will soon have, probably, bring it.

Only in the night. Even probyval device put on the collector, after 3 hours, when I came kurnut - dead skunk. I could not tolerate 5 min. And also in the night. In the duty room heated? Hush pitalka in the case when dry Konda of B + or a small container S817 ( necessary to select manually for each apparatus individually). In the duty room transistor must not die - the only reason - spontaneously switched briefly to the operation mode from power surges - the reason, I think, be found in the piping SCR MCR22 - very often, this scheme becomes unstable.
