When power on, no picture or sound just blinking red standby light. Three blinks then pause three blinks again etc. and again as long as power applied. Remote can still cause set to go standby with solid red standby light but then when try on again just get the blinking red light. I have no service manual or schematic yet but was hoping that someone would know what the problem is. Any ideas?

3 blinks is short protection on this model---98% chance one of the two STK-392-110 Convergence chips it uses has shorted.
If you unplug set and look inside you will find two black chips that have that number printed on the front of them in white letters. Right in front of them you will find about a dozen light blue resistors---most are marked 2.2 ohms---look if you get a chance---if even one of those resistors is white in the middle (discolored) you have found your problem.
Both chips and any bad resistors need to be replaced.
The repair involves getting at the parts and replacing them--the chips each are mounted side by side on metal heat sinks with fins--each has 18 pins.
Most shops get 300 or more for this repair but the actual parts cost if you or someone you know can do it is under 30 dollars.
I have START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR IN THIS SET. I got a notice from a lady who used them to fix the same set you have---she saved the set and a lot of money.
The instructions tell you everything you will need and how to do the repair----clearly I do not know how much skill you have---it involves soldering etc.
If you want the instructions I will post them here for you to look at and copy/ paste them. Once you read them you should know if you can do the repair------they are my own instructions based on doing this repair hundreds of times.
I will also post a photo here showing what the chips look like.
Repair takes me about 1 hour; if you are doing it for the first time it will take you longer.
I also know the best place to get the chips at reasonable price.

sounds like you have a intermittant thermal condition and this could be the regulator IC the video jungle/sweep Ic. Anything in the switching poewer supply or sweep curcuit. This is a hard one unless your there with a meter and a schematic to measure voltages when the set goes out then you can use a can of freez sprasy to lightly spray on the supected part. Sorry i cant be of more help. Good Luck

You goingto need to replce the powersupply inside www.partstore.com should have it or preorder it for you from the manufacture i think there around $150 they could be cheaper. Another option is Ebay. thanks for using fixa.com please rate.
