Hitachi 53uwx10ba turns on & off when off red flashing light/clic

Same problem. Replaced both convergence ICs about 5 months ago. Worked fince since then and just recently no sound, no video, blinking red on front panel and clicking sound. I suspect that the ICs went bad again and blew a resistor or two. I used cheap Chinese ICs instead of the Sanyo ones and thing this is why. I'll be looking at it again and post solution.

RCA 52inch Model R52WH77 HDTV

may i suggest reading the ariticle the fl231 problem in my tips and tricks section of my profile. YOu MAY have a 5 dollars 30 minuter fix. Determine if you have the convergence option under the setup option of the customer menu. if you dont then congratulations you have a simple fix. i you do have the convergence option and the autoconvergence then you might have other problems. and will have to troubleshoot further. If so ill talk you through some more. THIS set has NO stk convergence ics. my feeling is the fl231 which i see alot on this perticlar model at the shop

The two convergence ICs labeled STK392-110 are bad . Likely the resistors that go with them one or more are bad too.
If you have patience can use a ohm meter, solder properly and have good vision. You can fix this problem .
Parts can be found at . Good luck, maicomasher

JVC AV-48WP30 will not give a picture

Replace the convergence IC`s again using original Sanyo chips (STK 392-110 or STK 392-180). Make sure to use plenty of heat sink compound. Coat the entire back side of the chips. Also look to see if any of the low ohm resistors are burned. A shorted chip will cause the thumping sound and the set will shutdown. I am guessing that you used generic IC`s as a replacement. They are cheap and the leggs fall off when you apply too much heat during soldering. Dont wory about the CRT driver or the deflection board, they are probably fine.

Convergence and wavey picture problem

Actually you have 3 problems. The two that you listed and the third which is: Apex does not support their units. Ask anyone who has tried to get any service. Your problem sounds like a bad digital convergence box. I fix this problem several times a week but on name brand sets. Cost is usually less than $100 for the part. Some problems with Apex equipment can be fixed if the part is a common off the shelf part. That is not the case with your problem. Apex equipment is cheap for a reason. All posts that I have read say that they do not last long and you can't get parts. That has also been my experience as a technician. We don't even accept Apex units for repair anymore. Next time spend the extra money to buy a name brand unit and it will more than likely be repairable.
