SOURCE: Philips 42PF7220A/37 42'' TV (LED flashes red 7 times)

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

Panasonic tx-55as650b TV red led flashes once repeatedly - inverter circuit?

Hi Jimbo, generally this issue is from defective LED lamps, the inverter is shutting down because of over current because of shorted LED's. All the main board knows (the board that issues the error codes) is the inverter shut down, it has no way of knowing why.

Sony CRT TV type:DRC-MF DR34M69, long time to ON, LED stand by blinking red and green, how to solved this problem? Thank You.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Red drained out of picture

The red transister on the CRT socket could be at fault. there is 3 transisters on the socket check for the voltages on all 3. If the red is high unplug the socket and see if it normal if not the transister or circuit feeding has a short. If low the same case seneral applies and a resistor feeding the transister is defective or the transister itself is at fault
