Where i get the EHT of Akai Tv
EHT or Extra High Tension is the power supplied to the final anode of the cathode ray tube.
The EHT is traditionally generated by the line transformer from the flyback pulse of the line oscillator/amplifier.
The generated high frequency high voltage current was from the outset rectified by a thermionic diode (eg. EY51, EY86) but by the late 1960s/early 1970s technology brought high voltage diodes and semiconductors rapidly replaced the old technology and the output from the line transformer then typically fed the anode via a semiconductor voltage doubler.
The rectified EHT was originally smoothed by a high voltage oil-filled capacitor but that was soon deleted in favour of spraying the outside of the CRT with a metallic paint and grounding it. This became the high voltage smoothing capacitor with the glass of the CRT being the dielectric and the final anode the positive pole...
My Akai has lost a much watched channel overnight. I have tuned the channels, but still unable to recover. What else can I try?
Check if the channel is off-the-air due to an issue at the transmitter. After a severe storms, some local stations lost their transmitter because the tower fell. More often, the transmitter hardware can fail. One station repeater near me had an interesting period where it didn't get the incoming signal from the primary transmitter.
Check that your antenna hasn't shifted to point away from the transmitter. Reposition the antenna, if needed. If you have an amplifier on your antenna, check if that has been damaged. If it has been damaged, replace it. My household found that the antenna/splitter became a filter for one VHF channel when damaged by a lightning strike. The check was to connect the antenna to one TV without the amplifier.
The other common issue is interference. Has there been construction in your area that added a large building between you and the transmitter?
I hope this helps.

How do i fix my akai tv stuck in startup screen
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.
