During the servicing of a receiver whose chassis is not isolated from the AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in personal injury from electrical shocks. It will also protect the receiver and it's components from being damaged by accidental shorts of the circuitry that may be inadvertently introduced during the service operation. If any fuse (or Fusible Resistor) in this TV receiver is blown, replace it with the specified.

When replacing a high wattage resistor (Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB. Keep wires away from high voltage or high temperature parts. Due to high vacuum and large surface area of picture tube, extreme care should be used in. With the instrument AC plug removed from AC source, connect an electrical jumper across the two AC plug prongs. Place the AC switch in the on position, connect one lead of ohm-meter to the AC plug prongs tied together and touch other ohm-meter lead in turn to each exposed metallic parts such as antenna terminals, phone jacks, etc. If the exposed metallic part has a return path to the chassis, the measured resistance should be between 1MΩ and 5.2MΩ.
When the exposed metal has no return path to the chassis the reading must be infinite. An other abnormality exists that must be corrected before the receiver is returned to the customer. Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good earth ground (Water Pipe, Conduit, etc.) and the exposed metallic parts.
Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or more sensitivity. Reverse plug the AC cord into the AC outlet and repeat AC voltage measurements for each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS which is corresponds to 0.5mA. In case any measurement is out of the limits specified, there is possibility of shock hazard and the set must be checked and repaired before it is returned to the customer.

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. 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.
