TV red led lights up but no sound or picture need manual
The Hitachi LE49S508 red LED lights up when the TV is in standby mode. The LED will be off when the TV is on or has no power. If you haven't tried the front panel buttons, check if the TV will turn on when you press the lowest button (Power) on right side of the TV. If this works and your remote doesn't, you may have a problem with the remote or the IR receiver. (You can check the remote by having someone take a picture of the front of the remote when you press a button. There should be a flare of light visible in the picture.) If your current source is a PC, make sure that the computer is on and hasn't gone to sleep. Otherwise, the TV main board is not getting power from the power supply or not responding correctly to the commands.
Sears Parts Direct has the owner's manual for the LE49S508 here: https://www.searspartsdirect.com/partsdirect/user-manuals/le49s508-hitachi-parts-manual .

I hope this helps.

Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.
SOURCE: TV does not turn on, blinking red LED
Problem is a bad audio IC esp if your are reciving 11 blink code
if it is a 5 blink code replace Crystal 1h00 On Ssb new part number is 24225430 1397
SOURCE: No Picture & No sound. Red LED, Green LED, Red LED.
If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

I found this solution from SONY's website.
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
I hope this helps.
