My LG L246wp-bn has started having a start up problem. Standby light blinks on and off for a min or 2 then may or may not power up.If i unplug the power, it does the same thing but sometimes it will run. now it took 10 mins of power plugging to get it to run. Once running all is fine as long as it does not go to sleep mode. Cold or hot , same problem.

I recently fixed my LG L246WP-BN Flatron monitor. It had two bulging 3300uF 10V capacitors in the 5V section of the power supply. I made a complete repair tutorial video on how to fix:

Why LG L246wp not turning on or slow to start up?


Weak or almost dead power supply board. It can be changed as a DIY project. Google power supply and watch a youtube video. Really easy. Just unplug, removes ALL he screws on the back panel, unplug the 3 to 5 wire plugs from the board, remove the four screws holding it in place. Pop in the new board, replace wire plugs, install back cover. Plug into the wall and Press on button.

boards can be found on eBay, and tvpartsguy.com

look for the exact model number on the back of your tv first to match.

Standby light keeps blinking. tv wont turn on


If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Sony kds-r50xbr1 turns itself off and then green light blinks 52


I too have a Sony KDS-R60XBR1 tv and the issue that you are experiencing is due to one of your fans in the rear of the tv is not working.  The tv automatically shuts off in protective mode.  Make sure the POWER/STANDBY light is blinking and not the lamp light below it.  Is the power/standby blinking 4 times in red? If, yes then its a fan that needs to be replaced.  If its the lamp light blinking then you need to replace the lamp.  The lamp is easy to replace by ordering the lamp either from Sony for $250 or find it cheaper for approx. $150 from other DLP sources and replace youself by following your manual.  I hope this helps you.

Sony Triniton Wega Model KV 32HS510. After pushing the power button,the tv starts to power up, then the standby light blinks 7 times then pauses before blinking 7 times again. It continues to do this,...


This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.
