Thanks God for the internet and thanks for the service like this - proffessional solution on time.

About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

The downloaded quality was as good as the orignial

This is a great and complete Service Manual for the Sharp GF8585HB. Giving full and detailed technical insight. Good to find these manuals online.

Everything was ok with the manual. If I have a small complaint, is that I ordered it during the weekend and I think you guys were closed. But I did receive it late Sunday. I will surely order from you again

IMPORTANT SERVICE NOTES
Maintenance and repair of this receiver should be done by qualified service personnel only.
SERVICING OF HIGH VOLTAGE SYSTEM AND PICTURE TUBE
When servicing the high voltage system, remove static charge from it by connecting a 10K ohm resistor in series with an insulated wire (such as test probe) between picture tube ground tag and high voltage lead. (AC line cord should be disconnected from AC outlet). 1. The Picture tube in this receiver employs Integral Implosion protection. 2. Replace with tube of the same type number for continued safety. 3. Do not lift picture tube by the neck. 4. Handle the picture tube only when wearing shatterproof goggles and after discharging the high voltage completely.
X-RAY
This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions and servicing may produce potentially hazardous radiation with prolonged exposure at close range, the following precautions should be observed: 1. When repairing the circuit, be sure not to increase the high voltage to more than 25.5 KV, (at beam 1000µ�) for the set. 2. To keep the set in a normal operation, be sure to make it function on 22.4KV±1.5KV (at beam 800µ�) in the case of the set. The set has been factory - adjusted to the above mentioned high voltage. Always check the high voltage if there is any possibility that it might have changed as a result of the repair. 3. Do not substitute a picture tube with unauthorized types and/or brands which may cause excess X-Ray radiation.
BEFORE RETURNING THE RECEIVER
In addition to the above checks, the following safety checks should also be carried out before returning the unit to the user. 1. Inspect all leads and dress to make certain that the leads are not pinched or that hardware is not lodged between the chassis and other metal parts. 2. Inspect all protective devices such as non-metallic control knobs, insulating fish papers, cabinet backs, adjustment and compartment covers or shields, insolation resistor-capacity networks, mechanical insulators etc.
