Since the TV is already quite old, it is difficult to find remote controls for it, AV . It is quite simple to do this - switching video signals is carried out using a microcircuit of the TC4053B type - to switch to AV mode, a logical zero is supplied to pins 9 and 11 (a transistor is installed for this purpose). We simply short these pins to "ground" and that's it...
FUNAI TV2000 frequent defect of the power supply unit. Large leakage currents of electrolyte 100 μF * 6.3 V,
the result is that it does not turn on from the remote control and randomly turns off (optional). Replace only
at 100 μF*12 v.
FUNAI MK6-7-8 . A sign of malfunction is a broken R2M and a torn N20 - they
must be changed. And now about what was not australia telegram data mentioned.If R2M is not broken, and the power module does not
start, then measure the electrolyte 220 μF-6.3 V. It either has zero capacity or the ESR will be increased.
Funai-MK7 . It is not necessary to change the R-214 processor that has become so expensive so quickly, but it can be
“cured”. To do this, it needs to be shielded from above, placed in a tin case (at least
made from a tin can) and necessarily soldered to the “ground” of the TV. The
processor power supply capacity (+5V) needs to be increased to 2000 - 4700 μF.
The processor should be restored to working order immediately, and in a few days the indication will also be restored.
Option two - heat the processor (without desoldering) with a hair dryer or lighter. If with a lighter - then for 30-50 seconds, if with a hair dryer - then at a temperature of 250-280 degrees, also for 30-50 seconds. Apparently, something is soldered inside the processor, but this method helps very often.
Then the most ideal option is to make it forced
