The reason you're not finding any bad caps is that's not the issue. If it was the set wouldn't power up then shut down, faulty caps don't cause issues like this. One thing that would have helped is the model number but I have a good idea what's causing your issue. When the set is powered on it goes through the boot log sequence, this is stored in the EEPROM that's located on the main board, chances are if you take a can of freeze spray and freeze the IC the set will power up as this IC isn't used once the set has powered on but it would only work one time but it's a way to confirm if this is the issue. If you have advanced solder skills you can order an IC and replace it for under 20 bucks, but it's not something easy to do without the skills or equipment, the other option is replacing the main board, however that may run more than it's worth so buying a new TV may make more sense

eBay probably, or perhaps India Mart? In reality, the set is unreliable and needs replacing. https://www.mouthshut.com/televisions/Akai-CT-21W9-reviews-925002638 https://www.google.com/search?q=akai+tv+model+gt-21w9+eht+replacement https://www.ebay.com/b/Akai-TV-Boards-Parts-and-Components/163768/bn_738967 ..

Thunder is just the noise. The damaging thing is lightning if it hits a power pole or your house. It causes a power spike of thousands of volts which damages every component inside your television. You claim against your power utility company with the complaint that they failed to regulate the voltage. You buy a replacement set. They may have small print that says it was 'An Act of God', in which case you claim against your home insurance. They often have a get out clause that you have to pay the first $1,000 of any claim. You need a new set.

Your main board is defective

try to look for this..

Could be time for a replacement power board, if they are still available.

Have you seen inside? Check for bloated capacitors. The constant on and off may be charging and discharging bringing them back too life. It may also be just bad connections either externally or soldering.

It's either a faulty power board, or a faulty switch board or an overheating issue and the set is going into protection mode. You need a television engineer to diagnose and fix https://www.fixya.com/support/r29790007-repairing_own_television ..

The applicable code(s) would be in the remote control, if it is compatible.

Attach the antenna to the appropriate connector on the rear

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...

is it working ,i want the code

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. Cindy Wells

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.
