The most common issue here in the old sets is bad solder connections--the problem is you have to get the entire chassis free and up so bottom of boards face rear of set---look to power supply---a lot of 2 and 3 lead parts there from heat come loose from the boards and also to the middle of the set on the middle board.


If you are not able to attempt this the set is too old for a shop repair in my view as many parts for it are no longer available.

Hi there!
May be power supply related (old capacitors),dry joints on the main board or dry joints in the video amp section. Check for loose or bad connections. Good luck,JUS004

You definitely have bad solder grounds. I have repaired a few of these. You will need a TV tech pull the boards out and resolder them. The worst board would be the one on the left [signal board, has rca jacks. rf connector]. And they may as well solder the second board. You will have a restored TV when completed. Thanks for asking and show a few hands of support!

I have a 32" RCA LCD tv , rlc3210 power input says

Is it hooked up with HDMI cable?

If so try unplugging the HDMI cable and re plugging the cable in, sometimes those cables work loose and if they are not tight, it will cause your screen to flicker. Happens to my TV once in awhile.

No color

Confirm to me the brand and model number AND if you have not tried it=unplug the set for a while and then power up and see if that helps.

Mitsubishi VS50707 - picture went out while TV was on. Sound still works. if i turn it off for awhile then back on, all three color tubes come on and flicker together for awhile before going out again....

The most common failure is the convergence IC's for what you are describing. They are large black flat-pack items mounted on aluminum, finned heatsinks. They will have numbers on them like STK392-110 or STK392-120. Yours may be different but most start with STK392-___. There may be some resistors that overheated and failed,... they are usually mounted near the IC's. They will be darkened towards the middle area. Google "Mitsubishi convergence repair kit" and you'll find suppliers who will sell you what you need , quite often with complete instructions. Here's the first one I found: http://www.tvrepairkits.com/xcart/home.php?cat=2638 This link is for your model number.

Mitsubishi VS-55609 distorted Picture Flickers

This is a convergence problem and not really a DIY Many amateurs try it to save money but end up spending more on it than a professional. There are dozens on here that managed to fix it for a day or two only to have it fail again.

cost of fix about $300.

TV works fine for a while, then the picture disappears.

I would just replace the TV, the parts are not going to be made to repair this. The set is just to old.

Pioneer PRO-FHD1 Plasma Monitor Start-Up Problem. We bought this Panasonic plasma monitor 16 years ago and it has never been serviced, so all parts are original, and the unit has never malfunctioned -- until about a month ago. The system fails to power on. At first a month ago this happened rarely. We learned to unplug for a few minutes to drain the caps, then re-plug, and the monitor would start normally. Now, we plug-in, turn on the main power switch, and the red stand-by light illuminates. When we press the ON switch using the remote control or onboard switch, the blue Power light comes on for about 6 seconds as the screen goes to dark grey, then back to black, with a power board double relay click audible. Then there is another single relay click and the red Standby light flashes 3 times, then pauses about 3 seconds and repeats over and over. The screen stays black. Now, if we repeat the de-power/re-power process many times, the monitor eventually powers on, and functions normally -- until the system is turned off and cools down for a few minutes. If the monitor is shut-down and restarted while warm, it usually re-starts normally. All of the caps on the Power Supply Module look normal except one that was very slightly bulged, which I replaced, but I suspect that there is another component failure on that board. I have also physically plugged/unplugged all of the wire bundles to the Power Supply Module, and tightened the mounting screws. I've removed the board and closely examined it in the process of replacing the one suspect cap. The board is labeled as manufactured by SanKen, with a part number sticker showing: AXY1148BE0606008931. I took some advice, and used a hair dryer to heat the area of my supply board with the suspect cap, and the monitor started normally. I let it cool, and it failed again. I re-heated it and it returned to normal! Another heat/cool cycle confirmed that there are a few more bad caps that need to be replaced. I'll let you know...
