Subject: [TechAssist] JCV AV-27820 Dark picture - Brightness has no effect.
Hi,
This JVC has a very Drak picture. Brightness has no effect at all.
Voltages on CRT module are OK. Screen 402 volts, and is adjustabe.
200 volt siuce is 175 volts. CRT tests "very good".
Some resistors look overheated, and can't read the values on R526, R941, &
R544.
Working without a schematic. Anybody have anything on this one ?
Any help is appreciated, as usual.
