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...

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.

First try checking the "auto off" function. I am not familiar with Akai TVs so this advice is very basic. Use the 'Menu' button and find Settings, (It might also be listed as Set Up). Go into this section of the settings. There should be a feature listed as 'Time' or 'Timer'. Set this to Off.
Your other option, if it is a brand new TV is to contact the store you bought it from and ask their advice.

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.

On my Akai LCT2715---- Ok, I had the same problem with locating USER MODE (even called Akai service HELP and that person didn't know anything)!!! even tho we looked through manual just got TV back from putting $184 in Capacitors repair (PUT IN NEW NICHICON CAPACITORS) from the standby button not woking just flashing from the Power Supply gone bad plus 2 main capacitors other than power supply that were bad. Works great now. For the USER MODE look on the remote in the bottom black area repeatedly push the P.MODE. You should have full function to adjust all in menu list WE DID.

Try restoring it to factory settings. I found these instructions and hopefully they'll help you to disable the channel lock problem you have -

Hi Roger, your Akai PDP4290 TV, is a Monitor, does not bring antenna or cable input
To be able to use it as a Channel Television, you must use a Decoder of some Television service and connect it to one of the inputs that your Akai has
I hope you can solve the problem
Greetings Franco Dosil

Hola Roger, tu televisor Akai PDP4290, es un Monitor, no trae entrada de antena o cable
Para poder usarlo como Televisor de Canales, deberas usar un Decodificador de algun servicio de Television y este conectarlo a alguna de las entradas que posee tu Akai
Espero puedas resolver el problema
Saludos Franco Dosil
