Aqui está o esquema de um modelo Panasonic SA-AKX54 muito semelhante: https://www.electronica-pt.com/esquema/audio/panasonic-audio/panasonic-sa-akx54-23004/ Nas páginas finais, há uma lista de componentes com a posição da placa e seus valores.

Como ele não encontra esses componentes e assumindo que a falha esteja nessa placa, a vida não é complicada e substitui a placa inteira: https://produto.mercadolivre.com.br/MLB-763555773-placa-inverter-led-driver-m1950d-m2250d-m2350d-m2450d-m2550a-_JM

Mude diretamente a saída integrada STK433-070.

O problema é que há uma falta de tração no rolo direito do videocassete para avançar e no lado esquerdo para buscá-lo. O resultado é que a fita é empacotada dentro e ejeta o cartucho com parte da fita enrugada...

Check your rectifier bridge 1st, then also the Transistor and the Source Control Circuit.

Check the SMD components in the area of this Integrated Circuit and the Inverter Windings.

It is a backlight failure, check the voltage of 12 Volts from the source output to the inverter and also the state of the transformer. Here is the Service Manual: https://www.manualslib.com/manual/768465/Dell-E153fpc.html

To unlock the OSD, press and hold the [img]buttonhttps://cdn2.yoreparo.com/uploads/imagen_post/0003/94/17a6dbf50615619f23265181eb755f2ee0e0ca72.jpeg[/img] OK in the monitor menu for approximately 10 seconds to unlock. You can do the same to block the OSD again.

Here the scheme of a very similar Panasonic SA-AKX54 model: https://www.electronica-pt.com/esquema/audio/panasonic-audio/panasonic-sa-akx54-23004/ In the final pages there is a list of components with plate position and their values.

Since it does not find those components, and assuming that the fault is in that plate, life is not complicated and replaces the entire plate: https://produto.mercadolivre.com.br/MLB-763555773-placa-inverter-led-driver-m1950d-m2250d-m2350d-m2450d-m2550a-_JM

Directly change the integrated output STK433-070.

The problem is that there is a lack of traction on the right reel of the video cassette to advance and on the left to pick it up. The result is that the tape is bundled inside and ejects the...
